Spoiler: How to Install beta via OTA/IPSW [Guide]

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

Seeing some weird stutters that I haven’t in the prior betas.
Hopefully no more of those once things settle down.

Yes, seeing them as well, more so on my iPad than my iPhone.

OTA or ipsw?

 

[BriceApp]

OTA. I just restarted my iPad. Going to see if that clears it up.

Restart didn’t clear it up. Seems to studder when opening folders on the home screen.

 

[iOSBry]

Seeing them too on my iPhone 15 Pro; really bad.

Did a hard restart after my normal network reset after the beta 4 install and still seeing them.

Did a hard restart after my normal network reset after the beta 4 install - still seeing them.

I only see it when expanding/closing folders. Are you seeing it anywhere else?

 

[iOSBry]

I only see it when expanding/closing folders. Are you seeing it anywhere else?

I had ten app updates after the beta 4 install and was doing them and swiping on the Home Screen, opening/closing folders, and launching apps was really stuttery. Don’t believe I’ve ever seen it this bad.

Seems to have settled down after the app updates. Will keep testing.

 

[christian.terra]

only saw the stutter once since updating, but now seems fine. there is sometimes a slight delay at times when opening a folder tho..

 

[jazzzyJeff]

Opening folders have gotten better but now I see crazy stuttering when long pressing apps like Settings and then tapping elsewhere to go back. Happens almost every time.

Don’t remember any beta being this bad in recent years.

EDIT: Added screen recording.

not seeing that at all - maybe just needs more time to settle.

 

[Banglazed]

Public beta is out

 

[James6s]

Beta 4 has given a boost to performance on my 15PM. Happy & It feels like it should now! Battery life tbc.

 

[iFone88]

No stuttering my end consistent with what others have reported.

Notes widget issue fixed

 

[jazzzyJeff]

3+ hrs since installation and the stutter while long pressing app icons is still present on my 13P.

Reinstalling via ipsw proved no better.

 

[Cobold]

Something is off with the performance like waking up the CPU from sleep or so.
Try this: open a folder. Leave the folder open and don’t touch anything for 7 to 10 second. Then tap anywhere outside the folder to close it: the animation is totally messed up and stutters like crazy!

Can reproduce it 9 out of 10 times on my 14 Pro Max this way, but random stutter appearing throughout the system with beta 4.

I just switched back to beta 3 via iTunes. Couldn’t stand it.

 

[jazzzyJeff]

I'm seeing the same stutters on tvOS 17 beta as well. Something's really wrong with these betas.

Can second that this is duplicable going about it as outlined above.

 

[James6s]

Just checked the folder opening/closing stutter and I have this also on my 15PM. Tried screen recording but when recording the stutter doesn’t happen and it’s smooth! Lol.

App opening times and animations however are much better on this beta.

 

[jazzzyJeff]

Downgraded to b3 after those unbearably annoying stutters and now no more stutters.

Fingers crossed this doesn't carry over to RC next week.

 

[BriceApp]

Submitted feedback to Apple.

[Reeneman]

Animations are terrible in this beta 4.
Hopefully this will improve after everything settled down a bit.
Otherwise hoping for a fix in the 17.6 final.

 

[phrekaru]

It's an issue with promotion, activating limit frame rate helps with the issue

EDIT:
Went back to b3 😅

 

[SumYoungGai]

Started seeing stutter on 15 Pro Max as well, even after letting it settle all day. Reverting back to b3 with IPSW now

 

[James6s]

The stutter when tapping the screen to return an open folder back to normal size is still there this morning. Shame as everything else is spot on with B4. Feedback sent.
