Hello there !
Newcomer to the SketchUp world and Pro subscriber since a few days ago.
The desktop version runs fine on my brand new M2, but wouldn’t start on my Macbook Air M1. The app doesn’t open, becomes unresponsive after just a few seconds, while using 100% CPU. I saw similar testimonies in a number of other unresolved threads here. Both my Macs run on latest 13.3 Ventura OS.
The only workaround I found was to start the app in Rosetta mode, even though the app is supposed to run natively. This behaviour is the same for both SketchUp 2022 and 2023 versions on this computer.
Any idea ? Happy to provide more info.
Thanks !
Louis
Do you have any extensions installed? Is SketchUp 2022 and 2023 both in Applications?
You could try running SketchUp in Terminal, and see if that then shows more error messages. Open Terminal, which is in Application/Utilities, and paste in this line to run SketchUp:
/Applications/SketchUp\ 2023/SketchUp.app/Contents/MacOS/SketchUp
Does it then run? Otherwise, what messages are put into the Terminal window? You may need to set Get Info back to not using Rosetta before doing the test.
Hey Colin ! Thanks for the quick reply. Indeed, it does run fine when launched from the Terminal. I have a bunch of extensions installed since I work as an audio engineer and web developer.
I’d be happy to solve the underlying issue, but since I always have a Terminal window open, I honestly wouldn’t mind launching SketchUp via a command 
EDIT: Forgot to mention that both apps were in the Applications folder when ran.
It’s possible macOS quarantined SketchUp at some point. In Terminal you can run this line, then see if SketchUp opens normally.
xattr -d com.apple.quarantine /Applications/SketchUp\ 2023/SketchUp.app
Perfect, it worked 
Thank you so much !
