Today, Sat Jan 17th, as I had read blogs that indicated that the installation bugs that appeared in Oct 14 had been fixed, I felt it was time to upgrade to Yosemite. I upgraded my mac book pro (2013) to Yosemite 10.10.1 and unfortunately both Photoshop and Bridge stopped working. I uninstalled them and reinstalled them to have fresh versions and still did not work. I restarted the computer again, and they don't work. Im a prof photographer and need to have them running urgently. What do you suggest I do?
