If your Mac is running slow There are many ways to correct the issue. To check for memory issues, first open Activity Monitor. Select Quit and then select the issue you’re encountering. If the process is taking up too much memory then you should close it and try again later. Alternately, you could make use of the System Memory tab to check if there are any other process that is slow that are running within your Mac.
A CPU issue is another reason for slowness on your Mac. Close any program that uses too much CPU. In order to do that, start the Activity Monitor and press on the “X” button beneath the window’s small buttons. You can use Google to search for the apps that are consuming the most CPU power but you don’t know which apps are. You’ll be able to see which apps have a negative impact on your Mac’s performance.
When your drive is full the drive can also trigger the Mac to slow down . Too many applications consume excessive memory, making the operating system slow. Try deleting files that aren’t being used or moving the files to a different location. Open Activity Monitor to see a run-time list of processes running in your Mac. Some errors will be apparent – they are an indication that the Mac is running too many programs all at the same time.
