How to install beta via OTA?
  1. Enable Beta Updates (Settings>General>Software Updates>Beta Updates)
  2. Check and sign into the right Apple ID to access beta
  3. Select which beta you would like to receive (Public/Developer)
  4. Hit "Back" and pull down to refresh
  5. Do an encrypted backup or iCloud backup before installing the beta from release build
  6. Install the beta
If you no longer wish to receive beta updates:
  1. Turn off the Beta Updates (you can also sign out of your Apple ID to unlink your developer account)
  2. Wait for the next public release or follow the guide below to install the IPSW release build
Troubleshoot: Sometimes, the beta update will not show so you may need to enable/disable Airplane Mode or restart your device before rechecking for update.

How to install beta via IPSW on Mac?
  1. You will need to install either Xcode beta or MobileDevice.pkg which can be extracted from the Xcode beta (tap with two finger or right click to Show Package Content>Contents>Resources>Packages>MobileDevice.pkg - this will work on older Macs that do not support the latest macOS or Xcode beta)
  2. Do an encrypted backup in Finder in case you need to restore your device
  3. Hold down Option + Check for Update and select the appropriate IPSW file for your device (whether you're updating to a newer/beta firmware, reinstalling the same firmware or downgrading to previous firmware while retaining all your data) downloaded from Apple using your free developer account. Note: You must have an active internet connection as it will check the IPSW signing status before it will proceed with the update.
  4. Enter your iPhone passcode once prompted to proceed.
Notes/Tips:
  • Always keep a backup in case you need to restore your data if you restore your device
  • It may be better to close all apps before installing the updates and/or turn off your device for about a minute or restart a few minutes after your device is updated
  • You can also manually select the IPSW if you are restoring your device using Option + Restore iPhone. Restore will wipe all your personal data which you will need to restore your backup either using iCloud backup or Finder/iTunes backup
  • You do not need to install the MobileDevice.pkg from each Xcode beta version unless Finder does not recognize the new iOS beta
  • There is no MobileDevice.pkg equivalent to iTunes for PC which would require a new iTunes to support new/beta iOS
  • If you receive a new iPhone, you can connect to Mac to update or restore your device to the latest iOS before setting up your device.
  • You can also use the Recovery Mode/DFU to update or restore your device by manually selecting IPSW

Edit2: That is a pile of security fixes.
Indeed it is, just like I expected. I guess unless the battery life is disastrous or there is a memory leak, updating to iOS 17.6 is highly recommended.

EDIT: seems like even today’s Monterey update, which is macOS 12.7.6, comes with a ton of security fixes, including one affecting APFS file system. Not bad for one of the last security updates of good old Monterey.

Still nothing on Apples site of what the update fixes.


Edit: Fixed

I think you answered my question - thanks!

17.6 is available in Intune so was able to install it on mycompany phone (iphone 14) and also installed it on my iPad pro 11” M1.
Might be placebo or that the iPad had a restart when installing, but it feels smoother and more responsive that i remember it. Could be that I haven’t used it for a few weeks and forgotten how well it works.

Will wait for a day or two for my daily driver (13 pro) as I need confirmation that some apps are fully compatible with 17.6

I've just installed it, so we'll see how it goes, but normally it should

In the update's list of patches, I spotted fixes for two security flaws that allowed access to tabs in private browsing without authentication, as well as to the hidden album in Photos (again, without Face ID) ; so like someone above, I'd highly recommend installing it!
 
15 pro max... IPSW on Windows like I always do, and this time it "bricked" my phone. It failed 3/4 the way through the update and my phone was stuck on the apple logo. DFU restoring as I write this

Edit: I'm fairly familiar with restoring and such from back in the day of jailbreaking and how things worked... It took me 3 hours to get my phone back up and running. Multiple failed restores, different cords, different ports, different pc entirely. Once it was back on it would not activate, after multiple times I finally got it working by doing a full restore again, then resetting the phone via settings to remove the icloud lock, then restoring my backup... ugh!
