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

Nice. For all iPhone models still running iOS 18. Will update later tonight.

 

[Hans300]

19 builds newer than 18.7.7 …?

 

[Tmarto]

Hi everyone, I have a question. Has anyone installed this new version and would like to hear their opinion? Thanks in advance.😊😊

 

[addamas]

And once again have to scroll down to choose iOS 18 update…

Happy to see 18.7.7 was not last one on iPhone 11Pro

 

[katbel]

Every device in our house had the opportunity to update to iOS 18.7.8 but my phone 14Pro
Even an iPhone 16 that is newer than mine could do it
Why?!
@Tmarto Anyway all working well and no issues to report

I'm still running iOS 17.7.2 and consider finally - teeth grinding - to update to iOS 18.7.8, which is astoundingly still offered as an update path from 17.7.2. You'll only have to scroll waaayyy down, to see the option.

Anyone still here, who did the jump to 18 from 17 and is happy about that? I'm very cautious, cause I really don't adore 18, but seeing 26 performance (and look!!) on older devices, I finally consider updating to 18, to continue to use my 12 Pro - which I really like on iOS 17.7.2! 👍

Please give me a push... 😉🤣

Meanwhile I gave in and updated to 18.7.8 - thereby cleaned out the mail and photos app.

Wise decision about update! iOS 17 is full of holes, only iOS 18.8.7+ and iOS 26.4+ are for now safe for banking etc.

Also 12Pro works great same as my 11Pro?

One serious backlash I just noticed:
For inexplicable reasons the iCloud backup on iOS 18 is much bigger than it was on iOS 17, although nothing changed on my phone data wise. The rumors that successive iOS updates "eat up" your iCloud storage seems to be ultimately true! Just got a message from iCloud that the storage is nearly full - damned! 🤮 🤮 🤮
