Hey all,
I have a 2011 mac pro that I was only able to use safemode to play CoH. After reading through the various threads I did the following which fixed the issue for me. I can now play 32-bit beta or in the 32-bit link as well.
1. I trashed the CoH folder in my applications folder. I also had another icon for CoH in that folder, which I trashed as well. I left the rum folder alone.
2. I then started rum, selected 32-bit and tried to launch CoH. I had a big error message that said it couldn't locate the game files, so it started redownloading everything, including the Wine files.
3. After everything downloaded, I pasted in the beta manifest to see if that would work - it did.
4. I pasted in the safemode manifest to see if that still worked - it did.
5. I finally tested the normal 32-bit mode link to see if that worked now - it did.
6. Just tested 64-bit mode link and that now works as well.
So trashing the CoH files and redownloading worked for me.
