Hi, I could update successfully to Mavericks my 10.8.5 hd. I just had to use kext utility and concerning kext for audio alc882 and re enable trim.
Unfortunately I have a bad issue with flash. Any time I try to play something on you tube and even in FB, both firefox or safary freeze and I must reboot.
I tried to install flash again. No way. I don't know why. Of course I had no problems at all before updating.
Flash version is 11.9.900.117.
Any help or suggest would be really appreciated.
Thanks a lot.
