Just let you you folks know, especially those still on snow leopard, 9.1.8 has caused nothing but spinning beach balls every time I try and use Logic. Even after I reverted to 9.1.7. So it must have changed more than just the program. I'm dead in the water here. (Everything else is running just fine. 2009 intel iMac, 2.8, 4 gigs ram, hd checked and working perfectly) I vaguely remember years ago when a similar problem occurred, I solved it by dragging some folder into the trash. Trouble is I can't remember which folder and where it was located. Can anyone help me out here?
