I performed the TenFour patch on my wife's Mac mini running Mavericks and it worked perfectly. When I tried it on my Mac min running the Yosemite beta the system would not reboot and I ended up having to boot from the Yosemite Recovery Drive and reinstalling Yosemite to restore functionality. It may have been coincidental, but I am not going to try that again. Once burned twice shy.

I know, that's what I get from running a beta OS. tongue

If we knew what it was we were doing, it wouldn't be called research, would it?
