I have i-mac Pro 27 Inch Retina 5K (Late 2014 model).
The computer performance was extremely good.
However, after upgrading to mac OS Catalina 10.15.6, the performance has become extremely slow.
Even opening an app, system preferences, Shutting down and restarting take enormous amount of time (in terms of minutes).
Is there a fix to this problem?
Thank you.
Two suggestions. Try reinstalling the OS to see if that helps. If it still does beachballs after doing that, consider adding more RAM as I suggested earlier.
Do a backup, preferable 2 separate ones on 2 drives. Boot to the Recovery Volume (command - R on a restart). Run Disk Utility and select First Aid. Then re-install the OS.
Reinstall from macOS Recovery.

I have already given Full Drive access.
I don't why the report shows limited drive access.
I am attaching two reports after re-giving Full drive access.
2.. slow computer, opening apps - Beachballing
3.. Cache memory
You are welcome. Are you running any anti - virus programs? Using a VPN?
Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.

If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply. The program was created by Etresoft, a frequent contributor.

Thanks a lot, and apology for late response.
Here are my observations:
1) I am not running any anti - virus programs
2) I am not Using a VPN.
3) The problem persists in other accounts as well: both admin and standard user
4) In safe mode, performance is nearly the same (slow), but a little better than normal boot.
5) I am attaching the report after running EtreCheck.
You might want to add some more RAM since you only have 8 GB. The report shows only 66 MB of free RAM.
Virtual Memory Information:
Physical RAM: 8 GB
Free RAM: 66 MB
Used RAM: 4.78 GB
Cached files: 3.16 GB
Available RAM: 3.22 GB
The 2 places I’ve seen recommended most to buy reliable RAM are below. I have purchased RAM several times, a MacBook Pro battery, and 2 hard drives from Other World Computing and have always been very satisfied with the product and service. They have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the maximum. I had 6GB installed on an early 2008 iMac supposedly limited to 4 GB and noticed an improvement.
Thanks a lot for quick response.
Except installation of RAM, everything else suggested has been done multiple times.
First aid, disk erase, reinstallation of OS has been done many a times.
But the issue of slow performance and beachballing persists :(
Many thanks.
