macbook pro 13 inch 2015 getting very slow

my macbook pro is becoming very slow and system calls lack of memory --> shut down apps for more memory.

I uninstall many apps, but the problem stay's.

Would a full factory reset do the trick?

MacBook Pro 13″, macOS 12.7

When RAM memory is in short supply, you do not need to delete Applications, just Quit them to make amore room.

A restart will make a lot more room at once.


If you have only 8 GB of RAM, it is very difficult to run advanced MacOS like 12.7 Monterey with two applications at once in an appropriately-responsive way. You may find that you have to Quit your browser to run another App.

Consider downloading and running this little "discovery" utility, Etrecheck. It changes NOTHING. Etrecheck was developed by a senior contributor here, and uses mostly system calls and simple tests to collect often-needed information.


it contains little tests for speeds of devices, CPU utilization, memory usage, energy usage and a digest of recent problems, in one easy to use package. it does not even need to be Installed. Because less can be learned when your Mac is running great, best time to run is when your problems are actually occurring, if possible.


if you follow the directions faithfully, its report (pre-laundered of all personally-identifiable information) can be "Shared" to the System ClipBoard, then Pasted into an ‘Additional Text’ window in a reply on the forums.


Use Etrecheck Pro for free:

The amount of data you get can be daunting. If you POST your report, some Readers here are willing to look over those reports, and can provide valuable insights.


Then start a reply on the forums, click the "additional text" icon, and PASTE
