Just discovering the memory leak issue! I set up my brand new shiny 24 inch iMac with 16 gig memory and from the get-go it was in operable. It froze with one Word document and one Brave browser window open. Constantly restarting just to get anything done. Multiple tech-support calls involved running first aid, reinstalling the OS and it still crashes because apps are using way! Too much memory. Ultimately I sent it back to Apple for a replacement. I am learning from researching online many people are having this issue. As a diehard lifelong Apple fan, I am really disappointed and disillusioned. Especially the Apple is not recognizing the issue or offering a fix.
