Activity Monitor displays only one column

Activity Monitor does not display any columns or data except for Process Name. MBP 15 inch 2019. MacOS 10.15. Attempted OS reinstall but the problem remains. Don't know if scaled resolution (1280 x 800) matters.


Does anyone else have this issue? Is there a way to resolve it? Thanks.

Workaround (works for me for now - not definitive):

  • booted into Safe mode
  • viewed My Processes
  • scrolled right and was able to adjust width of Process Name column, dragging to left until other columns were visible

This survived after a normal boot.
