Hi,
I am regularly having a problem where copy/paste stops working, and drag and drop stops working as well. The console shows dozens of messages like this:
Finder[315]: CFPasteboardRef CFPasteboardCreate(CFAllocatorRef, CFStringRef) : Lock timeout
Whatever the frontmost application is sends those messages. The only solution is to restart. Does anyone have an idea what is happening?
Many thanks,
Aparajita
MacBook Pro with Retina display, OS X El Capitan (10.11.3)
Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem.
Note: If FileVault is enabled in OS X 10.9 or earlier, or if a firmware password is set, or if the startup volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.
I'm also having the same issue as can be seen from this thread:
Re: Drag and drop in finder stops working
However logging in and out or booting up in safe mode would fix the problem, and this only happens like once a week. I haven't tried disconnecting all peripherals but I tried quitting all possible programs, including everything that I found that was running in the background, like Alred, Sizeup, RescueTime etc.
So, I found out why this is happening but only have a lame workaround:
pboard seems to be locked by something.
The workaround is:
