Spoiler: GUIDE: How to install?

To get the beta over-the-air:

1. Enable Beta Updates (Settings > General > Software Updates > Beta Updates)
2. Make sure you’re signed into the right Apple Account
3. Select which beta you’d like to receive (public/developer beta)
4. Hit "Back" and pull down to refresh
5. Back up to a computer or to iCloud
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 Account to reset this setting)
2. Wait for the next public release or follow the guide below to go back to a release build

Troubleshooting: If the beta doesn’t show up on your phone, try turning on airplane mode, then turning it back off, or restart your device.

How to install using a Mac?

1. You’ll need the Xcode beta itself or a MobileDevice.pkg somebody extracted from the beta (click with two fingers or control-click), then choose Show Package Contents. Go to Contents/Resources/Packages. - this will work on older Macs that do not support the latest macOS or Xcode betas)
2. Back up to your Mac or to iCloud in case you need to go back to another version
3. Hold down Option, then click on ‘Check for Update’/‘Restore iPhone...’ and select the IPSW file you downloaded from the Apple Developer site. Note: You must be connected to the internet to complete the restore.
4. Enter your iPhone passcode if you’re prompted to do so.

Notes/Tips:

• Always keep a backup in case you need to restore your phone
• Restoring wipes your settings and all data on your iPhone
• You only need to reinstall MobileDevice.pkg if your Mac stops recognizing your iPhone
• There is no MobileDevice.pkg equivalent to iTunes for PC which would require a new iTunes to support new/beta iOS
• Upgrading to a newer iPhone? You can update using your Mac before setting up the phone

Woo!

 

[WilliApple]

Apple fr be using indie dev app release schedule

At least it's out.

Uhh I hope this is just the indexing cause my Air is a stuttering mess after installing this.

Update: looks like it was my air getting hot and throttling with the update. It’s now a bit smoother altho the lag from the widget page to Home Screen is even worse now and still hitches everywhere.

 

[papbot]

Nothing appearing yet.

My air has no stuttering after the update

Exactly the same on my 16 pro. Very disappointing

 

[thatJohann]

My Air is def still stuttery. Little hitches everywhere when scrolling. So bizarre. Feels way worse than 26.0.1. Hope it’s indexing stuff slowing it down because this is a big downgrade.

 

[papbot]

I had to toggle off/on Automatic updates for it to appear for my ipad.

 

[Ron21]

The visual glitch with app icon border outline when closing the app is back in this build

NVM, resolved after reboot.

Never had any stuttering problems on my air. Its bin running great on the beta

Haha what? Why?

 

[MacQwé]

Installing on Iphone 13. Beta 4 was okay-ish

 

[Artemiz]

Blank wallpaper bug after installation came back in RC.
Thought it was resolved in beta 4 but Apple being Apple I guess.

 

[william16promax]

Can someone confirm if the tinted glass toggle still present ? Don’t want to update from beta 4 if it’s not

 

[mariuskv]

It’s there

Still there.

 

[Lounge vibes 05]

Automix is still busted for me.

 

[william16promax]

It’s there

Fantastic, love most parts of iOS 26 but the tinted toggle makes it look better to my eyes

 

[mariuskv]

I went tinted when they added the option 😂

 

[TimAppleObamna]

The border redraws??? I thought that was finally fixed

 

[Dust-by-Monday]

Why are some of the beta 4 fixes being reversed in the release candidate? That’s so weird

 

[TimAppleObamna]

General iOS 26 question, does anyone else NOT have these shiny borders that move? Mine are fixed and I thought they move as you move your device.
iPhone 13

 

[adrianlondon]

Not fixed:

- Shortcut action "Turn on/off Always On Display" will crash if AOD is already in that state
- Can't create stacked widgets on the Today View screen (have to create elsewhere and drag them over)

Overall I'm happy with iOS 26.1, but then I'm one of the few who likes the new design, it seems.
