After updating DP2, Lion won't boot on my MBP Core Duo. I know for the first DP you had to remove platformsupport.plist and it was good to go. But now it seems DP2 updated doesn't work with that trick. I've been searching around but cannot find anyone else who has mentioned this issue who also has a core duo. Does anyone have any information on this or what to do to make it work on Core Duos again?
