Thanks @ProTruckDriver , I upgraded to Sonoma. I'll check out my iMac 2021 Dang Apple messes up their updates and I waited too before upgrading. 🤬 Better hope I don't have to contact their Support line or  link!!!

Thanks for this. This is a good article and few things I need to check out on my machine.

So I followed the article to see what might be causing a slow down. And then I read this: 

5: Use Activity Monitor to Discover Performance Hogs

Sometimes, a Mac runs slow because there is an errant process, or an app going wild and using an inordinate amount of system resources, grinding the entire machine to a halt.

Open Activity Monitor (/Applications/Utilities/ folder), and click on the “CPU” tab to sort by CPU usage. Next, go to the “View” menu and choose “All Processes”. If you see something at the very top using a large % of CPU, you’ve likely found your culprit, or perhaps a lead, as to why the Mac is running slow. You can also sort by Memory to discover things consuming your RAM.

So I did as this said and was surprised to see what might be slowing down my machine!

So basically both Carbonite and Webroot are using more than 215%? Only mds_stores is using more, and it comes and goes.  Anyone care to comment?   🙄
