Suggested March 2024 Airdrop Says ‘Waiting’ But Never Sends, How To Fix
You can use AirDrop to send or receive items on your Apple device. You can share files such as photos, locations, URLs, or documents with people nearby using AirDrop. AirDrop only works with Apple devices. When you AirDrop a file to another device, there are three steps: It will first say “Waiting…,” then “Sending,” and finally “Sent” once the file is successfully sent. Usually, AirDrop file transfers occur almost instantly. However, sometimes you may notice that your file may never pass the “Waiting” step and never connects to the other device. The receiving device never gets the “accept / decline” message. AirDrop says “Waiting” and then fails. In this article, I explain how you can fix this problem.
In AirDrop, there are two parties: sender and receiver. It is important to understand that this problem may be caused by the sender’s or receiver’s device. Thus, the following steps should be followed on both devices. Before you do anything, ensure that both devices are running the latest version of iOS, iPadOS or macOS.1. Is AirDrop restricted?
The first thing to check is Screen Time. It may be that Airdrop is turned off.
Tap on Screen Time.
Tap on Content & Privacy Restrictions.
Tap on Allowed Apps. You will be asked to enter your Screen Time passcode. Enter it.
Ensure that AirDrop is enabled.2. Off, Contacts Only or Everyone
There are three basic settings in AirDrop:
Receiving Off: You won’t receive AirDrops.
Contacts Only: Only your contacts can see your device.
Everyone: All nearby Apple devices can see your device in Airdrop.
These settings are available:
Review these settings on the receiver’s device:
Ensure that AirDrop is not set to Receiving Off.
If the receiver AirDrop setting is “Contacts Only,” ensure that your contact info is found in the Contacts app of the receiver’s device. Furthermore, both the sender’s and receiver’s devices should be signed into iCloud. And lastly, the sender’s Apple ID email or phone number needs to be present in the Contacts app of the receiver’s device.
If your contact is not in the Contacts app of the receiving device, they should set AirDrop to Everyone. Try selecting Everyone. If this fixes the problem, then this means that you probably do not have a connection issue. Check that the contact details are stored accurately, and check that the sender or receiver is not blocked (see number 5 below). If the contact details contain any outdated info, update them.4. Check connections
To establish a proper connection between the two devices, ensure that the following are true:5. Blocked contact?
If any of the sender’s or receiver’s emails or phone numbers are blocked, it may cause this problem. Check your Blocked Contacts to ensure that the sender and receiver are not in the list on each device:
If you (yes, you may have blocked yourself mistakenly) or the recipient is blocked, or if you are blocked on the receiving device, unblock it.6. Time Zone
Ensure that the time zone settings on sending and receiving devices are set correctly. You may want to turn on the Set Automatically option so that your device will do that for you. Here is how:7. Reset network settings

Immune cells are like the Hatfields and McCoys of our bodies–once wronged, they never, ever forget. This is how we gain immunity, and it’s why vaccines work: Immune cells develop a memory of an invading pathogen, and they build an alert system to find and fight it should it ever return. But a new study by Stanford researchers adds a new wrinkle to this long-held immune theory. It turns out immune cells can develop this memory-like state even for pathogens they’ve never met. This may come from exposure to harmless microbes — or the memories may actually be borrowed from other, more experienced cells.
The findings could help explain why babies and small children are so susceptible to infectious diseases. They haven’t been exposed to enough ever-present, mostly harmless pathogens yet, and it’s the constant scuffle with these bugs that gives adult T cells a sort of cellular precognition. “It may even provide an evolutionary clue about why kids eat dirt,” said the study’s lead author, Stanford microbiologist and immunologist Mark Davis. Kids are drawn to dirt because they’ve got to expose their fledgling immune systems to something, to help build up their defenses.
Davis and his coauthors studied a group of T cells called CD4 cells, which are the same ones targeted by HIV. CD4 cells hang out in our bloodstreams and stand sentinel, sounding the cellular alarm when they spot something that doesn’t belong. There are two basic classes of CD4 cells: Naive cells, which haven’t been exposed to a particular bug and might take a while to mount a response, and memory-type cells, which have done battle with a pathogen and are on the lookout for it again. The memory cells can prompt action within a few hours, while naive cells might take days or even weeks–meanwhile, we’re sick.
Decades ago, Davis discovered that CD4 cells reshuffle their DNA when they divide, which basically creates an army of T cells that have very specific pathogen-recognizing abilities. According to this new paper, this ability might also help them recognize pathogens they haven’t even seen yet.
The researchers looked at blood samples from 26 healthy adults and figured out which T cells were responsive to which pathogens. About half of the cells looked like they were in the memory state, meaning they would have encountered a particular pathogen in the past. But then Davis and his colleagues did some tests and found out those people were never exposed to those diseases. They also tried this on newborns, using umbilical cord blood, and found the babies’ cells were naive.
To test this further, the researchers took two adults who hadn’t had a flu shot in five years and gave them the vaccine. After this dead-virus invasion, which is designed to give CD4 cells a new memory, the patients’ CD4 memory cells proliferated. But interestingly, some of them were awakened to “remember” different bacterial and protozoan cell structures, which had nothing to do with the flu.
How do naive cells accomplish this microbial memory generation? It’s all about the environment. People are constantly exposed to countless bacteria, fungi and viruses, everywhere all of the time. T cells might act like they’re reacting to something they’ve seen before–maybe the bacteria’s proteins look similar to that of a harmless bug, and the cell is fooled. Or maybe the actual memory cells reshuffle their DNA when they replicate, which gives new cells specific properties.
“The pre-existing immune memory of dangerous pathogens our immune systems have never seen before might stem from our constant exposure to ubiquitous, mostly harmless micro-organisms, in soil and food and on our skin, our doorknobs, our telephones and our iPod earbuds,” Davis explains.
So maybe drop that Purell habit and don’t worry about the billions of bugs, most of which aren’t harmful, that surround us all the time. They might be giving our immune systems a head start.
The research appears this week in Immunity.
There may be an evolutionary reason why kids are inclined to eat dirt.
In the absence of reliable figures from Apple, it is not much more than conjecture to say that AirDrop is likely a feature often neglected by the average iOS user. The gut feeling persists though, simply based on day to day observations, and it is a tenable position to take until proven wrong by Cupertino or another reputable source. The file transfer protocol is indeed handy for the transfer of heavier media files (e.g. videos, photo albums), but often only becomes relevant to us when we for example have upgraded to a new device.
Next to sheer transmission speed however, there are other notable areas where AirDrop has the clear edge when it comes to sharing all kinds of material from your iPhone. The AirDrop icon has now fully permeated the sharing tab in iOS 10’s user interface and that is for a good reason: it is without fail going to be more nimble than iMessage, Mail or other contenders, often actually skipping steps that would throttle the process elsewhere. Such being the case, here are some unique scenarios where AirDrop excels on your iPhone and why you should try to embrace the feature more regularly.Sharing Safari links
When added to the UI a few years back, many users must have wondered who on earth would want to AirDrop a Safari website. If not in practice, at least in theory the answer should be: everyone. A tap on the share icon in the bottom bar of Safari, followed by a touch on your friend’s circular icon is literally all it takes for the receiver’s iPhone to automatically pop open the page in question. By way of contrast, sharing a link through iMessage or any other app means sending out a link first, which for the recipient most often means switching to such app, hitting the link, then being redirected to Safari. What sounds like no big deal is nevertheless a perceivable difference when you try it – AirDropping links is super speedy and swiftly eliminates a step between sending and opening.Sharing Contacts
Similar to the Safari case, sharing Contacts is fairly straightforward and has probably been executed a couple of thousand times worldwide since you started reading this sentence. Alas, it is just as certain that only a small fraction of these contact cards have been transferred by means of AirDrop.
Why is that unfortunate you ask? Because the AirDrop mechanism once more is superior: sending it via iMessage and the like implicates opening iMessage and touching the card, which will subsequently pull up the contact and ask you to Create New Contact or Add to Existing Contact. After choosing, you are prompted to edit and save the card. Contrary to that, accept the Contact card via AirDrop and you will have the simple option to Save the card in the top right corner. Done.Sharing Apps
Just like with links in Safari, sharing an app (either via the App Store, or 3D Touch on iPhone) through AirDrop cuts out the intermediate step of having to physically open the link on the receiving device. Hit share, tap the recipient’s bubble and watch his or her iPhone jump from the home screen straight to the recommended app. It’s as effortless as it gets and straight up cool.Sharing Podcasts
This section should probably be titled Did you know that you can share a Podcast? instead. Anyways, you can. And if you ever feel the need to, try to use AirDrop if circumstances permit. In line with the previous examples, sharing by means of AirDrop eliminates the middle man and circumnavigates any other app that would merely dispatch a link. If you want to make sure the Podcast of your choosing is for sure looked at by the recipient, AirDrop will take care of it. If accepted on the receiving end, the phone will directly launch the Podcast’s page.Apple Music Albums and Songs
While only pertinent to Apple Music users, this is again the most direct, cheeky and almost intrusive way to impose your musical whims on your friend’s device. A shared album is going to make the recipient’s phone jolt straight to the album. Even better, share a song via AirDrop and if accepted it will immediately start playing the track. If you and a buddy hang out, you can now be the DJ of his or her iPhone… right from your own device. Needless to say how this beats out sharing via iMessage!

In April, I wrote a blog post, “Domain Names Have Become True Commodities”. It’s now June and the market for Domain names is still rising in prices. It’s much like the housing market two years ago, not quite as hot and profitable yet, but there are a lot of people making serious money from domain names.
Duncan Reily of TechCrunch reports on the domain name market in his post, “Domain Sellers Party Like Its 1999”. The last time domain names were this hot was 1999-2000. It is now 2007 and the market is back.
The announcement of chúng tôi on sale in the market has sparked major interest in not only web business aspect, but also the domain itself which I believe is a big part of its price tag estimated at around $300-$400 million dollars.
Reily reports, “Last week some $10million changed hands at auction for domain sales, with 16 domains being sold for 6 figures. Free Credit chúng tôi & Credit chúng tôi sold together for $3million, although as the DomainTools Blog points outYour browser may not support display of this image. this was at a relatively low multiple of around 7x yearly earnings. chúng tôi sold for $1.8 million and even chúng tôi raised $135,000. The exuberance in the market even extends to the spam infested .info domain, with chúng tôi selling for $17,000.”
Many people who don’t follow the domain market, which is much like a real estate type of market, are wondering if they should hold on or sale their domains. “Ultimately it’s up to the market to decide the value of anything; however the domain sales market appears to be outperforming the established site marketplace,” reports Riley. Personally, I would put any domain you may have of value in the market now and see what the market would estimate it at.
Over $10M worth of domains sold in Moniker’s Live Auction last week in New York. Here is a list of some:
Why the iPhone will never be free
Back in August of 2011, I wrote an article entitled Why the iPhone 4S will be Free. As it turned out, the iPhone 4S was not “free” until the release of the iPhone 5s. The iPhone 5S is “free” right now here in 2014, if you close your eyes and pretend you’re not paying for it in your monthly bill to your mobile provider. The concept I spoke of back in 2011 is dead, now, and I no longer consider said concept to be a possibility for Apple.
This week there’s a rumor that the iPhone 6 might be “free” upon release. Don’t trust anyone who suggests they’ve got some inside word on how Apple will deliver the iPhone 6 in an entirely non-traditional way with wireless carriers.
Tradition will hold. If the iPhone 6 is offered for “free,” it will be done in a way that’s very, very similar to the company’s lowest-tier iPhone in any given set of three. At the moment the three iPhone models available to the public through Apple are the iPhone 5s, iPhone 5c, and iPhone 4S. These three iPhones have pricing tiers which will be basis for the release of the next iPhone or iPhones.
The reason I use quotes around the word “free” for the iPhone 4S is that customers still be pay “full price” for said iPhone with their mobile data carrier. The price is tied in to the monthly bill they pay for services, even if they can’t see it separated from the rest of the cost markers.
T-Mobile USA has tried to clarify this mysterious mode of business – to a certain degree – in the recent past. T-Mobile’s most recent model for smartphone sales show potential users exactly what they’re paying for their phone in the long and short-term.
If T-Mobile USA doesn’t offer a free iPhone off-contract, there’s no such thing as a free iPhone. T-Mobile USA does not and likely will not offer a free iPhone any time soon.
Motorola is making a big effort to kick the cost of a new phone down to the bare minimum with the Moto G and Moto E. Given the iPhone’s speed of evolution away from its origin, a free Apple-made smartphone might never exist.
Instead we’ll have to rely on a startup to create an ecosystem in which a free smartphone could potentially exist. This company would need to provide near-impossibly simple means for brands to push their apps to their operating system. They’d also need to find a way to profit from those apps, and they’d need some big-time funding to create their “free smartphone” in the first place.
Do you know of anyone aiming to push a free smartphone to the market? Even if you’re reading article this several years after it’s been published, I’d love to hear from you. Let’s have a chat – on these free phones, if at all possible.
Study says human age limit reached
Research released this week suggests that human lifespan expectancy has reached its limit. Scientists lead by Xiao Dong, Brandon Milholland, and Jan Vijg have concluded that improvements in survival with age “tend to decline after age 100.” These researchers have concluded that maximum lifespan of humans “is fixed and subject to natural constraints.” Sorry, Ricky Bobby. You’re not going to live to be 245 or 300 years old.
Using population data for more than 40 countries around the world, these researchers have shown that those countries have been having a decline in late-life mortality since the 1990s.
Survival improvements since the 1990s for people age 100 and up, meanwhile, seem to peak – peak at around age 100, that is to say. Diminishing gains, dropping life.
Image above: “Professor X” from upcoming film “Logan”, captured by James Mangold, via Twitter, “Taken w/ Leica S 007 Summicron 100mm, ISO 3200 1/250 ƒ3.4”
It’s not as if attempting to save people’s lives might not possibly lead to a person living longer than the maximum age these scientists suggest. Maybe. But chances are, they’re right, and humans cannot live beyond 125 years. Total. No matter what.
“Demographers as well as biologists have contended there is no reason to think that the ongoing increase in maximum lifespan will end soon,” said Jan Vijg, Ph.D., professor and chair of genetics, the Lola and Saul Kramer Chair in Molecular Genetics, and professor of ophthalmology & visual sciences at Einstein.
Vijg is senior author on the paper published on age this week. “Our data,” continued Dr. Vijg, “strongly suggests that [maximum lifespan] already has been attained and that this happened in the 1990s.”
The International Database on Longevity was used by this team to find “maximum reported age of death” for people verified as living at least to the age of 110 between the years 1968 and 2006. They also limited their search to the four countries with the largest group of longest-living humans.
Between 1968 and the early 1990s, age at death continued to increase. In the year 1997, the still-oldest-person to ever live (ever documented, that is), died at age 122. She was Jeanne Calment and she lived in France.
Facts / Conclusions before and as a result of this study:
• USA lifespan expectancy in 1900: 47
• USA current lifespan expectancy: 79
• Average maximum human lifespan today: 115
• Oldest living human: Jeanne Calment, died in 1997 at age 122
• Absolute maximum human lifespan: 125
• Probability of person living to absolute max lifespan: 1 in 10,000
“Further progress against infectious and chronic diseases may continue boosting average life expectancy, but not maximum lifespan,” said Dr. Vijg.
Dr. Vijg also offered a suggestion to those individuals and groups working now to increase lifespan beyond any we’ve yet seen in humans. “Perhaps resources now being spent to increase lifespan,” said Dr. Vijg, “should instead go to lengthening healthspan—the duration of old age spent in good health.”
