altcomputing Posted August 7, 2014 Share Posted August 7, 2014 I just managed to get my Sapphire HD4550 (1002:9540) to nicely work under Yosemite Beta. No problems so far. Edited AMD4600Controller.kext and ATIRadeonX2000.kext with proper ID's. Use kext-dev-mode=1 for Clover. Dropbox link below; file attached to post also. Enjoy! https://www.dropbox.com/s/9pfan5tu2n8rknd/KEXT_HD4550_YosemiteBeta.zip KEXT_HD4550_YosemiteBeta.zip 1 Link to comment Share on other sites More sharing options...
