Activity Monitor is broken

Activity Monitor no longer shows center data columns under any of the tabs.

Installed OS 10.15.2 and reinstalled OS from Recovery. iMac late 2015.

Applications list appears at left and moves around, indicating changes in relative activity, but the center of the screen is blank.

Activity Monitor Won't Load Activity Monitor will not load on my Mac. When I double click Activity Monitor to open it, nothing happens. No error messasge; it just doesn't open.

I've read this older thread, and I've tried it's suggestions but nothing has worked: https://discussions.apple.com/thread/2244144 -I deleted the plist file for Activity Monitor -I booted to recovery mode and ran First Aid. -I made sure Activity Monitor was located in the Applications > Utilities folder. (I had never moved it from there). -And I tried to restore Activity Monitor from an old Time Machine backup. None of these steps has helped. How do I get Activity Monitor back?

Activity Monitor displaying only processes, no other info This afternoon I opened Activity Monitor (in the course of answering another user's question), and found that the window is devoid of information other than the Process Names. Normally, columns are shown that indicate CPU utilization, process uptime, number of spawned threads, etc., such as in this image borrowed from Apple's Activity Monitor User Guide: In my case, there is nothing displayed other than the Process IDs. The header bar with the column labels is likewise blank. Secondary-clicking in the header bar shows the column selection dropdown, and the appropriate items are checked, but not showing. This is the case for all tabs, showing just the CPU tab below: Selecting and/or deselecting columns to show has no effect. I have tried force-quitting Activity Monitor and rebooting the Mac, also with no effect. I have iStat Menus installed, and that appropriately displays the processes and their CPU utilization, RAM allocations, etc. 2019 16" MacBook Pro, macOS 10.15.6 with SU applied. Suggestions on next steps?

Thanks.

I also deleted the file com.apple.ActvityMonitor.plist.lockfile. If the system wants that file too, it can create it, I figure.

That solved it, but adjusted column widths are not saved when the plist file is updated during the session, nor when I quit Activity Monitor, and the plist file is again updated. I tried reading the file with an editing app, but couldn't figure out where anything is.

Try deleting…

~/Library/Preferences/com.apple.ActivityMonitor.plist

then reopen Activity Monitor.

You're welcome. The column widths aren't retained for me either.
