I have been playing ET on a macbook pro and haven't had a problem until now. I was having an issue with the UI, and it would quit ET. I tried a few thing, then just gave up, i coped my etkey and then deleted everything else. I reinstalled et from a flash drive that my friend gave to me, it was about 4 months old files. It worked fine for five minutes the it lagged like it had lost connection and then started working again, but my fps was way down around 10, and i used to get around 80. Also it had and error message about PB in distress, auto update failed (a1382 c2.254). this issue has progress and now i can't play for more than a minute without ET quitting. i have tried everything that i know of. Has anyone else had this PB problem with a mac?
