Offline simulator v.3.3.0 shuts down on Mac.

Hello,

I also have a MacBook Pro M1 2021, under Sonoma, version 3.3, and for me, works correctly.

Have you tried downloading and installing again?

Hi! I've tried that multiple times, erased everything connected to the software and also tried downloading it on an ext hard drive. Nothing worked so far... I've read that many others have this issue, but I haven't found a solution yet. 

Yep, checked all those. Nothing seems to flag any problems. The ColorSourceLauncher has access to my folders and my security level allows apps downloaded outside of App Store. 

Ok that’s curious!
Try creating a new "Test" session and launching the application.

That helped! My guest session shows no problems at all... What would you say is the solve?

This may be a folder permissions issue caused by an Eos installer that ends up blocking CS from writing to its persistent storage.

Some older versions of the Eos installer had a bug that they would create the ETC show and persistent storage folders with the wrong permissions, so that Eos is the only application that can write there. Updating Eos won't change this as the installer only sets permissions if it creates the folder.

If that's happened then Eos works just fine, it only affects the other ETC applications like CS Offline, Concert etc.

Make sure the "owner" of these folders is your user, and not "system":

• $HOME/Documents/ETC
• $HOME/Library/Application Support/ETC

Note that Library is a hidden folder so you'll need to use command + shift + . to see it in Finder

Indeed, as Richard says, it is an authorization problem.
The easiest way is to go to the "library" folder as indicated and delete everything ETC
$HOME/Documents/ETC
$HOME/Library/Application Support/ETC

Amazing! This worked! Thank you both so much for the help :D
