Indeed, repeated rebuilding will do little to fix it if it\'s a mac-only problem. The only full crash log posted here shows the usual \"crash on quit\" that everyone gets - it\'s an old, boring crystalspace bug. The compressTexture one is interesting, it might indicate that there is a problem with texture compression extensions or Apple GL drivers, so that\'s useful information.
Can someone describe, concisely, what the problems they have are and exactly what mac, graphics card, and OS version they have?
Thanks,
Daniel
