I installed Titanium on my Mac, it runs fine under one user account but crashes immediately on startup on the other user account.
Crash details can be found here:https://appcelerator.lighthouseapp.com/projects/25719/tickets/374-titanium-crashing-on-startup
Any tips appreciated - thanks!
I found out that it is a permissions problem, you need to make everything in the /Library/Application Support/Titanium writeable by the user you want to run as.
I copied all the owner permission to group, using something like this and it solved the problem:
chmod -R g+u /Library/Application\ Support/Titanium
I have this problem too. Please fix because I want to install on other developer iPhone. I need another user account to prevent iTunes mixing.
