Mac OSX port 1.53 (113) - Core Image Filters Crash

[radiohead14]

question for the port dev.. i believe zones? every time i use Core Image filters (sharpen luminance specifically).. the game's guaranteed to freeze/crash after a few minutes.. this always results with my last save (game is Secret of Mana 2/Seiken Densetsu 3 for this example) not registering. i will use a save spot, and then when the game freezes.. i have no other option but to force shutdown. the next time i turn the game on.. my last save is no longer there, instead.. the save before the last is the one that only registers. is this a common/known issue? is there a workaround for it? please help. i really love how the game looks with these extra filters, but it seems like the only way for snes9x to not freeze, is to avoid them completely.

by the way, i'm runnin OSX Lion 10.7.5
