One of our Mac mini 2018 16GB on Catalina version 10.15.7 has CleanMyMac (CMM) installed. In the last 2-3 weeks, CMM has been alerted us that our RAM is maxing out and prompts us to FreeUp space. We do that. A few days later, we get another prompt. Today, I noticed that CMM is telling us Safari is using a lot of RAM. Our use of Safari has not changed. We are basic users.
What could we be looking at to troubleshoot this new behavior and alerts?
RAM isn’t like Storage space in a computer, it should be pretty well used as close to maximum as possible. [EDIT, I actually mean, “There is very little benefit to having unused memory” ]
The only time you may notice “issues” is when you’re using more than the amount of RAM in your computer as it either compresses inactive memory use or “swaps” out application memory which is not actively being used to the Hard Drive, and even swapping these days isn’t a major issue with fast modern SSDs.
I’d ignore CleanMyMac on this unless you’re experiencing system slow downs which hinder you.
I’ve seen this quite often. Ignore it - CMM pops up irritating (and for the most part useless) alerts to remind you how useful it is
If you genuinely run out of RAM - and disk swap space - MacOS will let you know and suggest you close apps. However, that’s an extremely rare occurrence
You can ignore it or you can go into the notifications tab in preferences (CMM X) and uncheck the box for the RAM message. I have the M1 Mac mini with 8GB of RAM and a M1 MacBook Air with 16 GB of RAM and would periodically receive this message from CMM X. After unchecking the RAM notification box, I did not notice any problems.
How much harddisk/SSD space do you have left? The OS uses a swapfile on these can consume a fair amount of disk space. If your hdd/ssd has less than 20% free space, I would recommend cleaning up and see if that improves the situation.
Do NOT delete the swapfiles themselves as it will impact MacOS.
I had the same issue on my M1 mini. Initially, I freed up RAM using CMM, but it seemed to make my mini less stable. I set it to ignore the CMM notification and have not had a memory issue since.
Try ignoring Clean My Mac (and turning off its notification for RAM shortage) and see what happens. I predict nothing will happen and your Mac will be just fine.
