takeawaydave Posted January 26, 2015 Share Posted January 26, 2015 Hello - I have gone away and been using 10.9 for a while now. Now 10.10 is here and I feel stupid and may be have forgotten the little I knew. Anyway installed using the Yosemite installer from 10.9 on to 10.10 separate SSD. My active HDD is disk1 with 10.9 and when I try to boot on to new 10.10 Yosemite I get: Memory allocation error! Add: 0x05d804a8, Size..... I have installed most recent Chameleon 2.3svn r2549 to both 10.9 and 10.10 partition. not much i can find on this error AMD R7 270 GPU not 270x I have edited Info.plist of 2 files already with required id.
