I figured it had been long enough for the major issues to be worked out, but I guessed wrong. Since "updating" to Yosemite 10.10, Lr 5.6 keeps freezing, and the laptop restarts itself. I have reinstalled Lr, and it seemed to make the issues go away but they are back tonight. Freezes on import, freezes in the develop module.
Any idea's? This is driving me nuts.
15" rMBP, 8 gigs RAM, i7 something or another. Files are on an external Lacie drive. Worked fine on Mavericks.
