I cant drag and drop any more in finder somehow. it was working fine, now it works and then i have to restart or it is not working at all. what a mess
Occasionally drag'n'drop failures —where it just stops working— I experienced already with Yosemite, so it may be a VERY old bug. :) Usually you would see "CoreDragError" codes popping up in the system.log
Rather than rebooting, I just kill "pboard" in Activity Monitor, and afterwards restart a few GUI programs that were directly affected (including Finder and Dock.)
My wild theory is that Firefox is the culprit. At least the issues happened more frequently once I had to switch to Firefox for proper content blocking extensions. Anyway… I have no idea how to prove that, so it's just a guess, not a blame.
Well, I've been sitting on Sequoia this whole time, because I decided to sit Tahoe out, based on what I heard on HN. Maybe I'll sit Golden Gate out too!
