Suggested April 2024 How To Fix Ethernet Problems After A Recent Mac Security Update

As my colleague Christian reported on Saturday, some Mac models have been plagued by non-working Ethernet ports after installing a new security update outed by Apple. Although a lot of modern Macs don’t even have an Ethernet port, many models still carry it and many people still love using a wired internet connection because it’s faster, more reliable, and more secure than a wireless network.

The security update, known as “031-51913 Incompatible Kernel Extension Configuration Data 3.28.1,” reportedly blacklists the Broadcom BCM5701 driver used by the Ethernet port that comes standard on many Mac machines.

Fortunately, there’s a light at the end of the tunnel for anyone experiencing issues with their Ethernet ports after installing this security update. Apple has issued a support document on Sunday that notes how to fix the problem. In this tutorial, we’ll go over the steps to fix the problem yourself.

How to fix your disabled Ethernet port

Since those of you with a disabled Ethernet port after installing the latest security update will probably want to get it up and running again, Apple has provided a fix for you.

The first thing you need to do is check to see what version of the “Incompatible Kernel Extension Configuration Data” you have installed on your Mac is. Apple says that if you have version 3.28.1 installed, you’ll need to install the updated version, which is 3.28.2, to fix the problem.

There are two ways to do this – 1) connect to a Wi-Fi network to circumvent the Ethernet port altogether so you can install the update that way, or 2) if you rely on Ethernet, and cannot connect to a Wi-Fi network, you’ll have to roll back your most recent update so you can download the latest security update instead.

So with that being said, the first thing you need to do is check to see what version you have. You can do this by:

2) Opening the “Software” section, and opening the “Installations” section.

4) Looking for “Incompatible Kernel Extension Configuration Data” in the list.

If the latest version you see is 3.28.1, then you need to move on to the steps below. On the other hand, if you see version 3.28.2 in your list like you do in the screenshot example below, then you’re already good to go and you have no further actions to take.

How to fix the problem if you CAN connect to Wi-Fi

If you’ve determined that 3.28.1 is the latest version on your system, you can fix the problem by connecting to a Wi-Fi network and downloading the update over the Wi-Fi network instead of via your now-broken Ethernet connection.

Apple notes the following steps to get yourself all up-to-date with this Incompatible Kernel Extension Configuration Data debacle via Wi-Fi:

1) Launch the Terminal app from the Utilities folder found in your Applications folder, or from Spotlight.

2) Copy and paste the following command into Terminal, then press your Return key on your keyboard.

sudo softwareupdate --background

3) Enter your system password when prompted, then press your Return key on your keyboard.

4) Quit the Terminal app and restart your Mac from the  Apple menu in your Menu Bar.

That’s all there is to it. Your Mac should now have the updated Incompatible Kernel Extension Configuration Data and your Ethernet port should be up and running again.

How to fix the problem if you CAN’T connect to Wi-Fi

If you have no Wi-Fi network at home, or your computer is too big and heavy to lug around to someone else’s house to connect to Wi-Fi, then you’ll have to take a different approach. This is because with the latest security update, your wired Ethernet connection isn’t going to let you connect to the internet to check for updates.

If you fall into this category, you’ve got a little more work to do. Fortunately, Apple still has a fix for you, and with a little bit of patience, you can get your Mac connected to the internet again. Just follow these steps:

1) Restart your Mac into Recovery Mode, then move on to step 2. If you’re not sure how to do this, we’ve got a great tutorial on how to restart into Recovery Mode.

2) Once you’re in Recovery Mode, you’ll want to select “Disk Utility” from your OS X utility list.

3) Select your main boot drive from the sidebar  list in the Disk Utility app – by default, it should be Macintosh HD, unless you’ve changed it.

6) Quit the Disk Utility app and launch the Terminal app while still in Recovery Mode.

7) Enter the following command in Terminal, then press the Return Key on your Mac. Enter your password if you’re prompted to.

rm -rf “/Volumes/Macintosh HD/System/Library/Extensions/AppleKextExcludeList.kext”

Note: Replace “Macintosh HD” in the command above with the name of your boot drive if it’s named anything different. The rest of your command will be the same.

8) Quit the Terminal app and restart your Mac from the  Apple menu in the Menu Bar.

9) When your Mac starts back up normally, your Ethernet port should work once again. Now you need to install the latest update that fixes the Ethernet problem and gives your Mac the latest security updates. To do that, Launch the Terminal app on your Mac, enter the following command, and press the Return key on your keyboard.

sudo softwareupdate --background

10) Enter your password when prompted, then press the Return key on your keyboard.

11) Quit the Terminal app and restart your regularly Mac from the  Apple menu in your Menu Bar.

Once your Mac boots back up, you should be up and ready to rock again with not only a working Ethernet port, but also with the latest security updates. Sure, it wasn’t as easy as simply connecting to a Wi-Fi network to fix the problem, but it wasn’t that hard, was it?

Wrapping up

Hopefully you were able to just follow the steps of connecting to a Wi-Fi network, but fortunately Apple had a solution for those that still don’t use Wi-Fi in their homes. After following this tutorial, you should now have a working Ethernet port once more!

8 Pro Tips To Fix Iphone Contacts Disappeared After Ios 16 Update

Charmed by a plethora of eye-catching features, you upgraded to iOS 16 hoping to explore all the goodies including the full-on Lock Screen customization, Lockdown Mode, and the ability to create a private photo album. However, right after the software update, you were left scratching your head as all your contacts went missing.

Relax! This is the sort of issue that has existed on iOS for years. So, you should not panic as there are some viable solutions to fix iPhone contacts disappeared after the iOS 16 software update issue. And that’s exactly what I’m going to discuss in this in-depth troubleshooting guide. 

First off, it would be apt to figure out the causes of the problem as it makes our task of retrieving the missing contacts a tad easier.

Many a time, it’s the sluggish iCloud syncing that triggers the issue. And if your internet connection is also below par, the problem gets further compounded, thereby leaving you with a chaotic address book.

Beyond the ill-functioning iCloud syncing, you can also put the blame on a miscellaneous software glitch and wrong configurations. Having taken each possible cause into account, we have discussed solutions that can help you recover all the disappeared iPhone contacts.

While there is no doubt that iOS 16 is a massive upgrade, it’s not perfect in any aspect. Even though the latest iteration of iOS is still a work in progress, issues related to Face ID in landscape mode, unsend iMessage, and edit iMessage have cropped. That’s not all, the unexpected app crashing, depth effect Lock Screen wallpaper not working, and the rapid battery drain has also already got a fair amount of traction To help you easily deal with such problems, we have created a separate guide about common iOS 16 problems and their solutions.

1. Leave Your iPhone Alone for Some Time

Yeah, you got that right! It takes a while for iCloud to sync the entire data. Hence, you should give the cloud storage service enough time after the software update to do the job without any hindrance.

If the total size of the files is large, it will take a significant amount of time for iCloud to sync them. During this time, ensure that your iPhone is connected to a stable Internet connection. 

Besides, I would also recommend you connect the device to a power source. Since overheating and rapid battery drain are common phenomena post the software update, you shouldn’t worry about them either. After a while, everything will be back to normal. 

2. Restart Your iPhone 

When you are up against a common iOS issue that arrives out of nowhere, you should never fail to try a reboot. 

On your iPhone with Face ID: Press and hold the volume up/down button and the side button at once. Then, you need to drag the power off slider to shut down your iPhone. Now, wait for a few seconds, and then press the side button to restart your device.

On iPhone with Touch ID: Press and hold the side button and then drag the power off slider to turn off your iPhone. After waiting for a few seconds, press the side button again to reboot your iPhone.

Once your iPhone has rebooted, go to the Contacts app to check whether or not your missing contacts are back. If it has come back, you are good to go!

If your iPhone contacts are still missing, try turning off/on the iCloud for Contacts app. Many users who faced this issue have found success with this solution. So, it would be worth giving it a go as well.

Next, choose the “Keep on My iPhone” option to keep all the previously synced contacts on your iPhone.

Next up, restart your iPhone. When your device has restarted, navigate to the iCloud setting and turn on the toggle for Contacts.

Next, ensure that your iPhone is connected to an Internet connection. Then, wait for 20-30 minutes, and check if the disappeared contacts have returned on your iPhone.

4. Ensure That iCloud Can Fetch New Data Automatically 

Another reliable hack that you should give a chance is to allow iCloud to fetch new data Automatically.

Additionally, be sure the Push is selected for iCloud and the Automatically is checked as well.

If the missing contacts have not yet been returned to your iPhone, there is a good chance that the issue could be due to a software bug. And the best way to deal with such a situation is to update the software. Thankfully, Apple doesn’t take much time to get to the route of a prevalent issue and provide a workable fix. So, chances are pretty high that a quick software update might be waiting for you. 

Note that your iPhone must have at least a 20% battery when connected to a power source. Otherwise, the device needs to have around 50% battery to be able to update the software. 

6. Sign Out of Apple ID and Sign Back In

Now, we will sign out of Apple ID and sign back in. At times, you can resolve certain issues related to iCloud by just logging out and logging back into your account. So, we will give it a chance as well.

Open the Settings app on your iPhone and tap on the Apple ID banner/ profile.

Now, scroll down and tap on Sign Out. Then, make sure to keep a copy of all the important data like contacts, calendars, and more before signing out.

Next, wait for some time and then sign in using your Apple ID and password.

7. Reset All Settings 

You can count on factory Reset to resolve frustrating issues like this one. Well, I can say it as factory reset has been able to rescue me on numerous occasions. Keep in mind that a factory Reset will erase all the existing settings on your device but it will keep entire media and data safe. So, you shouldn’t worry about losing your important data.

8. Last Resort: Restore Your iPhone As New

If none of the solutions have worked in recovering the missing contacts, it is time to go for the nuclear solution. You guessed it! This time, we will completely erase the iPhone and restore it as new. But before going for the kill, ensure that your iPhone is securely backed up. If you haven’t done it yet, do it beforehand.

Restore Your iPhone Without Computer

For faster backup, connect your iPhone to a power source and ensure that the device is connected to a stable Internet connection.

Once your device has been successfully restored, set it up as new. During the setup, iOS will allow you to restore the most recent iCloud backup.

Restore Your iPhone With Computer

Connect your device to your Mac/Windows PC and select the device.

There you have it! I hope all the disappeared contacts have returned to your iPhone. But before you kickstart a gaming spree or go for binge-watching, make sure to share your thoughts and the solution that has worked for you. Besides, it would also be awesome if you could let us know any other viable tips that can fix this frustrating iOS issue.

How To Avoid Problems Getting The Windows 10 Creators Update

However, this is not your typical quality update that you get every month, the Creators Update is a big update. Technically, it’s a new version of Windows 10, and during the installation there are a lot things that can go wrong. At least initially, it’s expected that devices may come across errors and unknown bugs due to the fact that there are many different hardware configurations, and building a new OS is a not an easy task.

In this guide, you’ll learn a number of things you can do to avoid errors and other problems during the Windows 10 Creators Update installation. Whether you decide to use the Windows Update, Media Creation Tool, or Update Assistant to install the new version of the OS.

Create a full backup of your device

While installing a new version of Windows 10 should be a straightforward process, sometimes the installation may fail and the rollback process won’t work.

You should spend the extra time to create a full backup of your system to go back to the previous installation if something goes wrong.

Ensure enough storage space is available

Perhaps one of the most common problems is no enough space on the hard drive to complete an upgrade of Windows 10. Usually, you will see this problem on low-cost devices with limited storage capacity and older computers.

To prevent storage problems, make sure that your device has at least 20GB of free space available for the download and installation. If you don’t have enough space, it’s possible to use the Settings app to delete temporary and other unnecessary files. Alternatively, you can also connect an empty USB flash drive with at least 8GB to 16GB of space that Windows 10 will automatically use as secondary storage to successfully install the update. 

After the upgrade, you can use this Windows 10 guide to clean up the hard drive and reclaim disk space.

Remove security and non-essential apps

Sometimes security software could be the reason your device is failing to install the upgrade. If you’re running an antivirus, other than Windows Defender, or other security software, make sure to disable or temporarily uninstall the software before proceeding with the upgrade.

Older programs designed for previous versions can also cause compatibility problems, as such make sure to uninstall any software that make cause issues during the installation. You can always reinstall them after updating your device to the Windows 10 Creators Update.

Disconnect non-essential peripherals

Sometimes installation problems can be caused by a peripheral that is not compatible. To avoid any issues, you may want to disconnect all unnecessary peripherals, like printers, webcams, especially storage media (e.g., USB flash drive and external hard drive) connected to your computer — just use the essentials: network adapter to connect to the internet, monitor, keyboard and mouse.

Export important settings

It’s been known that sometimes after an upgrade, Windows 10 reset some of your settings, including privacy and default apps settings. If you have a particular configuration, make sure to note them before installing the new version to avoid problems.

Dealing with error messages

There are countless errors that can appear during an installation. If you’re having issues during and after the upgrade process, note the error code or exact message, and use your favorite search engine to research the problem. Typically, errors on Windows 10 are sometimes common problems with easy fixes. You could also find out that it’s actually a problem with Windows 10 that Microsoft is working to fix.

For example, an error that begins with 0xC1900101 (e.g., 0xC1900101 – 0x20004, 0xC1900101 – 0x2000c, 0xC1900101 – 0x20017, 0xC1900101 – 0x30018, 0xC1900101 – 0x3000D, 0xC1900101 – 0x4000D, 0xC1900101 – 0x40017) is usually a driver error. If you see error 0xC1900208 – 0x4000C indicates that an incompatible app installed, and it’s blocking the upgrade process. And error 0x80070070 – 0x50011 (0x50012 or 0x60000) typically means that your PC doesn’t have enough space available to install the upgrade.

You can contact Microsoft on Twitter (@WindowsSupport) to get quick help, you can contact the company directly, or you can take your computer to a Microsoft Store to see if anyone can help you.

Stop blocking feature updates

If you’ve previously configured your PC to defer Windows 10 feature updates, the Creators Update won’t download and install on your device.

In the case, you used the Group Policy editor to defer upgrades, you also want to make sure to undo these changes.

Disable network metered connection Reset Windows Update

Sometimes, you may not be able to download new updates because Windows Update isn’t working correctly. You can always try to reset the Windows Update components to fix stuck updates trying to download and install. If this doesn’t fix the problem, you can use the Update Assistant to install the Windows 10 Creators Update.

Install the Windows 10 Creators Update manually

You can use this guide to do a clean install of Windows 10 with the Creators Update.  However, if you prefer to do an in-place upgrade of the new version to keep your files, settings, and apps, you can use these steps:

Select the Upgrade this PC now option.

Once the setup wizard takes over, and it’ll proceed updating your PC. It should be noted that during this process, nothing will be erased, your computer will be kept intact with all your settings, apps, and files.

If you selected to keep Nothing, once the installation completes, you’ll need to go through the out-of-box experience (OOBE) to finish setting up your device.

This video will walk you through the upgrade process to get the Windows 10 Creators Update installed on your device:

If you’re not ready to deal with possible problems with the Windows 10 Creators Update, remember that you can defer feature updates until a later time, or you can use this guide to rollback to the previous version of the OS.

How To Fix Battery Problems In Iphone 7

So, you got a brand new iPhone 7 and have been playing with it day in and day out. It’s fresh and novel, and you just can’t get enough of all the new features – both in the hardware and in iOS 10 – that are not at your disposal. You’re having the time of your life until you realize that your brand new iPhone isn’t lasting as good as you expected it to. I mean, Apple claimed that the A10 Fusion chip is more power efficient and the battery is also larger, albeit marginally. Still, with all of that, how come you’re having your phone’s battery dying out halfway through your day?

In this article, we’ll look at some of the methods that you can employ to improve the battery life on your iPhone 7 and fix common issues that might be there. Please note that while we’re talking specifically about the iPhone 7, the tips apply to pretty much any iPhone running iOS 10, so they’re worth a try even if you don’t have the latest that Apple has on offer.

Do you even have a battery issue?

Before we go into how to fix battery issues, let’s first establish that you actually have an issue with your battery life in the first place. A lot of times, users report terrible battery life right off the bat on their iPhone or after they’ve updated to a newer OS version. In reality, whether it’s a new device or a major software update, the reality in most cases is that we’re just using the device a lot more. Trying all those new features and gimmicks results in longer screen-on times, which eats through the battery pretty quickly. Also, if you’ve updated an older iPhone to the newest iOS version, Spotlight will end up re-indexing everything, resulting in a pretty taxing load on the processor and high battery drain.

If the above isn’t your case, continue onto the tips that we list below.

Check your battery usage

Disable certain iOS 10 features

With iOS 10 on the iPhone 7, there are a lot of features that Apple added to make things more convenient. While they’re pretty nifty, then can take a toll on your battery, and disabling some of those might improve things for the better.

1. Raise to Wake

2. Connectivity features

iPhone 7 comes with a pretty full connectivity package, and you might not need all those features on at all times. For instance, you may not have a Bluetooth accessory paired at all times, in which case you can simply disable Bluetooth. Likewise, if there’s no WiFi available, it might help to turn off the radio. Also, if you’re in a poor cellular connectivity area, turning off LTE would be a good idea. Another thing you can experiment with is turning off AirDrop unless needed.

There’s no central location for all of iOS’s connectivity features, but most of them can be toggled via the Control Center that you can access by a simple upward swipe from the bottom of the screen.

3. Motion and Visual Effects

4. Siri Suggestions

5. Use (or don’t) Auto-Brightness mode

In reality, users have reported mixed feedback on this. Some users have had great battery life with Auto-Brightness on; others say it killed their battery life altogether. Experiment with both and pick the one that works best for you; just know that this option is there and you should play with it for optimal results.

Manage your options better

Many battery saving tips would recommend that you turn off a lot of features like Background App Refresh and Location Services. We disagree with that wholeheartedly. What’s the point of having a smartphone if you turn off a bunch of all those things that make it smart? Hence, our recommendation here is better management as opposed to outright disabling.

1. Background App Refresh

iOS 10 comes with a Background App Refresh feature that basically lets certain apps refresh and update even when not active so that when you load the app, it always has the most recent and updated data available without loading times. This is great, except that the default behavior of iOS is to allow every app to have this feature enabled, wreaking havoc on your iPhone’s battery.

2. Notifications

Notifications is another thing that you can micromanage to gain better battery life. By default, a vast majority of iOS apps will ask to send you notifications, but you don’t need notifications from all of them, do you? Perhaps you can survive without getting notified by a game, but definitely not without email notifications. The general rule is, if you don’t need to be notified by an app, don’t let it.

You can manage all your notifications by going to the Settings app and then Notifications. Go into each app that you don’t want notifications from, toggle off “Allow Notifications”.

3. Location Services

Here, first look at the list of apps and if you see something that shouldn’t be using your location, stop it. You may also select which apps can always access your location and which can only when you’re using them.

Oh, and while you’re here, do turn on the Status Bar Icon, as that will give you a much needed visual indication of when your iPhone’s GPS has been engaged.

4. App Closure

Use Low Power Mode

If all of this didn’t help, iPhone 7 and iOS 10 come with a Low Power mode that automatically kicks in when your phone’s battery hits 20%. In this mode, certain visual elements are disabled, background activity is halted and the processor on your iPhone 7 will clock down a little bit to reduce stress on the system. If you’re experiencing poor battery life, you can manually enable this mode as well. Simply go to Battery settings and toggle on “Low Power mode”. An indication of this mode being on is the battery icon turning yellow instead of the regular green (or orange or red, depending on battery level).

Restore your iPhone as New

So, you tried everything and your iPhone 7 still won’t last you long enough? Before taking matters to Apple, it won’t hurt if you restore your device and start fresh. Connect to iTunes in Recovery mode and restore the device, and set it up as a new iPhone instead of restoring from a backup. In some cases, it is possible that a bug had carried through your backups for a long time that is making matters worse. Setting up as a new phone will eliminate that chance and let you know whether it’s something on your end or with the device, after which you can make a better decision of which course to take.
