Apple has today released version 26.5.1 of the iOS and macOS platforms, bringing a fix for an issue with wired charging on iPhone 17 and iPhone Air devices, as well as a fix for an issue that could cause Macs with the M5 chip to unexpectedly shut down when content filtering extensions were in use.
As iOS 26.5.1 and macOS Tahoe 26.5.1 were not distributed to external testers prior to their release, and in the case of the former, is only available on iPhone Air and iPhone 17 series devices, we do not have any information on whether they contain any accessibility fixes for blind, deaf blind, or low vision users at the time of writing. However, as these updates appear to have been released to address a small number of specific issues, we do not expect them to contain any such fixes.
Release Notes
iOS 26.5.1
This update addresses an issue for a small number of users that may prevent wired charging on iPhone Air and iPhone 17 models when the battery is nearly drained.
macOS Tahoe 26.5.1
This update addresses an issue for enterprise users where Macs with an M5 chip could unexpectedly shut down when using certain content filtering network extensions.
How to Update
iOS 26.5.1 is available via Over-the-Air Update (Settings > General > Software Update), via Finder on a Mac with macOS Catalina or later, or via iTunes on a PC or Mac with macOS Mojave or earlier.
Before updating, we strongly recommend making a full and complete backup of your device (either locally or in iCloud, depending on personal preference). This will ensure that, in the unlikely event that something goes wrong during the update process, you will have a current backup on hand in case a device restore becomes necessary. Also, if using OTA update, we recommend plugging your device into a power source for the duration of the download/installation process, so as to prevent the unlikely event of your battery going dead during the update.
To install macOS Tahoe 26.5.1, choose System Settings from the Apple menu, select General in the table, click Software Update in the scroll area, and click the Update Now button to begin the update process. If other updates are available, you can click the Info button to see details about them and select specific updates to install.

Just check and nothing. 16 pro max. Hope is not just for the 17 and up. Long live cats and Chicago.
iPhone 17 and Air
From looking at Apple's Security Releases page, it appears 26.5.1 is only available for the iPhone 17 and Air models. Everyone else will presumably have to wait for 26.6.
iPhone Air and 17 series only...
According to the below article, iOS 26.5.1 is only for the iPHone Air and 17 series to address a wired charging issue specific to those devices. Doesn't look like it'll be coming to anyone else.

Interesting. I didn’t get that from the block post.
That’s interesting. I didn’t get that from reading the blog post. It said that it was addressing that specific issue for those devices, but it didn’t seem like it would only be available for those devices. That’s good though and I don’t have to do it. Perfect.
Update only available on iPhone Air and iPhone 17 series devices
iOS 26.5.1 appears to only be available on iPhone Air and iPhone 17 series devices, while macOS Tahoe 26.5.1 appears to be available for all Macs capable of running macOS Tahoe, regardless of chip. The article has been updated to clarify this.
OK, thanks that makes sense
Thanks Tyler, that makes sense. I checked on my iPhone SE and it said that my iOS was up-to-date. Well, now I know why. :-) Thanks for clarifying that for us.
