This morning the spacebar shortcut to the hand tool quit working. I reset my PS preferences (argh!) but that did not help. I saw on this forum that the culprit could be Chrome. I quite Chrome and now it works! Any advice other than don't use Chrome?
(I'm running PS 22.0.1, MacOS 11.0.1, and Chrome 87.0.4280.88)
I did some more reading on this forum and it's not so much Chrome being open but Chrome being open with a lot of tabs. I routinely have LOTS of tabs so I closed about a dozen and now everything (appears to be) fine!
Thanks for posting the answer!
Maybe this thread is long done, but invariably I've found that (in my case), OnePassword is the problem. The second I quit that app... voila: spacebar & hand/move tool functionality returns. Why would a password storage app affect this? The answer is simple: I have no clue.
Interesting. Although my problem was solved by closing tabs in Chrome, I do used 1Password!
Closing Chrome didn't fix this, but closing OnePassword did for me on my Mac. OnePassword has a shortcut, [period] + [spacebar], that you press to call up the OnePassword login modal, which I guess is a global shortcut that snatches spacebar presses away from Photoshop (occasionally).
