After upgrading to Catalina 10.15.5, my dock activity process shows an increasing bytes written until my hard drive is completely out of memory. When I restart I get all my drive space back, but then after a few hours the dock has eaten it all up again.
I've reinstalled Catalina, reset the SMC & PRAM, and killed the dock process. The only way I can get all my HD space back is restarting.
How do I fix this?
Mac mini, macOS 10.15
I'm glad to hear I'm not the only person with this problem - the entire internet had nothing at all on it and the Apple tech support guy had never heard of it.
The O/S installation repair did not fix it, and just wasted more time. I had to first back everything up on an external drive, then erase the disc, then reinstall the O/S.
Here are the instructions:
After speaking with Apple tech. support and hearing this was a novel event, I wiped my drive and reinstalled the OS. It appears to have solved the problem, at the cost of my afternoon.
I'm assuming this means re-installing all software? And an os instillation repair won't suffice to fix the problem?
I absolutely have this issue as well - MBPR Mid 2012, 2.6i7, 16gb DDR3.
Restarting won't clear the issue and sometimes even turning it off then back on won't clear the issue.
If you have exceeded 85% full, the Finder is trying to create a swap file with insufficient space to play around.
