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

iOS 17.6 RC or 18 Beta 4
Stability or fun, that’s the question here.
Click to expand...
I’ve participated in the last probably 5 beta cycles for the upcoming iOS version, starting with as early a build as I could get my hands on but this year I’ve sat it all out so far. I keep debating whether I want to jump on the iOS 18 train or not…I think I’ll wait until beta 5 to see how things are looking and decide.

I’ve got a regular 15, so no AI stuff for me, though I am highly looking forward to a few of the smaller QoL features they’ve finally added, that I’ve been hoping for for years like scheduled message sending, text formatting in iMessages and icons not locked to the grid. Decisions, decisions!

I thankfully chose the 15 Pro last year but honestly… until we got all the options that Apple has shown in their keynote we’re close to iOS 19 and the 17 iPhone models. It will take time and I’m still sceptical of this will really work as presented. 3rd party apps has to be updated as well that the AI can „read“ and understand what has happened in these apps, what kind of informations has been shared and so on.
For me in Germany it will take even longer due to the language and especially the EU regularities.
So honestly I don’t think you will miss that much with your regular iPhone 15 and in 2025 you will probably upgrade to a iPhone 17 model. Not that much to miss until then most likely.

Not directly iOS, but watchOS 10.6 finally fixes the regression that doesn't allow you to invoke a Siri shortcut simply by raising your wrist and speaking. Before 10.6, it would listen to it and then just kick right back to the watch face; it only worked if I said "Hey Siri" or "Siri" beforehand.

Installed 17.6 RC and everything seems fine. No stuttering at all, running smooth on 12 Pro. 👍

Many thanks to everyone! If battery life isn’t worse than on 17.5.1, I will update to install 17.6 from 16.6.1

Are there any tangible benefits to this update or is it just under the hood stuff?

Exactly. For someone that works in IT and that has always been an early adopter of a lot of novel technologies (one of my favorite phones was the Palm Pixi, and I’ve owned phones running every flavor of Windows Phone), I am feeling rather “meh” about all the AI hype.

On one hand, of course I have just a little bit of FOMO about not getting the AI features on this phone because it’s the new and shiny, but on the other I know that Apple’s AI will take another year or two to fully develop and mature so as you said, iPhone 17 will be the target.

18 is adding features that I have been personally hoping for for quite some time (T9 dialer, finally!), so I’m excited for it as is. I’ve also been considering grabbing a Moto Razr as a 2nd phone to play with and dip my toes into the foldable world as I have no hands on experience up to this point minus the leashed ones at Best Buy…
