Same issue with LR 5 and my apple bluetooth keyboard freezes. See my post yesterday. Tried calling Apple-no idea as to what is causing problem [ tried 3 different keyboards ]. Had same with LR 4 and called Adobe, no answer after sending them screen shots etc. A puzzel and exasperating. Need to use USB keyboard w LR 5.
I have a similar problem when using Photoshop CS6. Apple disown the problem and so does Adobe. Both blame each other.
Photoshop: Using the 'Clone stamp tool' causes the keyboard to 'freeze' every so often (usually accompanied with a short sound from the speakers).
Hold down 'cmd' & press 'alt' key 5 times seems to clear the keyboard until I use the 'alt' button with 'Clone stamp tool' five more times and I repeat
the process Hold down 'cmd' & press 'alt' key 5 times again!
Is this the same as your problem?
My solution works every time but a pain to have to do.
Hope this helps
I have a similar problem when using Photoshop CS6…
Are you also on Yosemite? Is your Photoshop updated to Photoshop CS6 v13.0.6?
Check the state of the battery because they are inclined to swell as they go bad with age; and the swelling interferes with the keyboard and trackpad which are located directly over the battery.
Right on target, Ann!
As a matter of fact, I acquired my Mac Book literally from the trash because my wife had discarded it when the Genius Bar at Apple told her the machine could not be repaired. I just ordered a generic battery from amazon.com for under $30 (no point in getting a genuine Apple battery, since those are the ones that swell in the first place) and the Mac Book has been working perfectly well since then.
