This hardcover version of this book, “iOS 15, iPadOS 15, macOS Monterey, tvOS 15, and watchOS 8 for Users, Administrators, and Developers”, includes full color images throughout the entire book.

Apple is on a yearly cadence for releasing new operating systems. Despite all of the troubles of 2020 and 2021, Apple has continued this cadence. This year’s releases of iOS 15, iPadOS 15, tvOS 15, watchOS 8, and macOS Monterey are somewhat lighter on new features that one might expect. However, the new features the operating systems have are big changes.

The biggest change is with a new Focus system, which will allow you to customize how your iPhone, iPad, and Mac all function when you need to concentrate on a particular type of task. The iPad has seen a significant change with the ability to place Widgets on the home screen. This will create a whole new experience, particularly with the extra large widget size.

For developers there are significant changes with Swift’s new async/await pattern, a whole new button system for customizing buttons, and a new continuous integration service called Xcode Cloud. Xcode itself has some improvements like inline commenting and the ability to review, merge, or close pull requests.

SwiftUI, Apple’s Swift-only UI framework has some enhancements with a new refreshable modifier, new button options, a new primitive called AsyncImage.

These topics just barely scratch what is covered in iOS 15, iPadOS 15, tvOS 15, watchOS 8, and macOS Monterey. The information within will provide details about all of the new features of each operating system and has something for everyone, no matter what level of expertise.

Strange Issues with two different iPads with Cellular

2011 2nd Generation iPad and 2017 2nd Generation 12.9-inch iPad Pro

Over the lats six months or so I have had to debug a couple of interesting issues with iPads, in particular iPads with cellular on them. The two devices were an 2nd generation iPad and another was a 2nd Generation 12.9-inch iPad Pro. Let us look at both of these, starting with the 2nd generation iPad.

2nd Generation iPad

2011 2nd Generation iPad

The issue that this iPad was exhibiting was that it would start randomly saying “Activating iPad”. The issues as intermittent and would do this upon reboot as well as when waking the iPad up.

Rebooting it would not fix it, as it would still give the same issue. Sometimes, letting it sit and attempt to activate would allow it to work, at least for a while. Before it would just be intermittent and happen occasionally, but starting in May it would do it consistently.

While sitting and pondering it for a bit, I came to realization of what was happening. The 2nd generation iPad had a 3G modem in it. The reason that it started doing it consistently in March was because the T-Mobile 3G service began to be shut down in March.

The fix for this was quite simple, remove the 3G SIM card from the iPad, and it works perfectly fine now.

2nd Generation 12.9-inch iPad Pro

2017 2nd Generation 12.9-inch iPad Pro

The second iPad that has been having issues is a 2nd Generation 12.9-inch iPad Pro from 2017. The issue started with the iOS 15.0.1 update. Updating to iOS 15 on this device was no problem, but starting with iOS 15.0.1 it would no longer update.

The update would download, but upon trying to install it, it would get stuck on “verifying update”. No matter how long I let it sit there, it would not do anything. I tried updating using a Mac, through Finder, but that also did not work. The same thing would occur, it would just sit there and spin at the “Verifying Update” window. I could reboot the iPad, and try again, but it would not do anything differently, just the same results.

Now, being the Apple nerd that I am, the fact that it would not update bugged me to no end. So yesterday, I wanted to really figure out what the issue was. I had tried doing some searching online previously, but everything that came up would lead me to a bogus solution.

That is, until this thread (available at https://discussions.apple.com/thread/253245929) came up from the Apple discussions forums, why it did not appear the previous times I did my searching, I do not know.

The first solution suggested to “Insert a SIM card and then do the update”, and after inserting a SIM card, and re-trying the update, it actually worked. The second most helpful suggestion on that thread indicated that simply removing the SIM card tray would fix the issue. I did not try this second solution, because the first one worked. It should be noted that the SIM does not need to be an active one, just any compatible SIM card would work.

Obviously, there must be an issue with iOS 15 and verifying an update on a cellular iPad Pro when there is no SIM card in the slot. It is not yet known if the same thing will happen when updating to iOS 16, or if Apple will actually fix it. It seems like these types of issues wait until major versions to be fixed. At least there is a workaround that does indeed work.
