Catalina memory issues

Although your issue with your Mac may appear to be similar to the OP's, the OP has not provided enough information for us to know if it is the same as yours. Let alone the solution for it. I suggest that you start a new post so that it gets the attention that it deserves.

Sorry, but that is just not enough information in order for us to be able to assist you with a potential solution.

I'm having the same issue. I leave my macbook pro on overnight, when I return in the morning I have a "Out of Memory, please force close some apps" window open. This has happened every night.
