I have the ISPW but tried to install GG in UTM and "an error has occurred" popped up right as it was starting the installation. Attempting to install on an Apple Silicon laptop, FWIW.

How do I fix this?
 
I used UTM to install MacOS through their script, which installed Sequoia, and then went to mrmacintosh.com and downloaded the file there. It all went pretty smoothly.
 
You need to download Xcode 27 and from it install MobileDevice.pkg & CoreTypes.pkg
They are in /Xcode-beta.app/Contents/Resources/Packages/MobileDevice.pkg & /Xcode-beta.app/Contents/Resources/Packages/CoreTypes.pkg
As of writing, Apple has not released them separately, as it usually does.
Download Xcode 27 from https://developer.apple.com/xcode/
