If your Mac keeps running slowly There are a variety of things that you can do to correct the issue. For a quick check of memory problems First, open Activity Monitor. Select Quit and then select the process you are having trouble with. If the process is taking up excessive memory, you can close it then try it again. You can use the System Memory tab as well to check if the slow-running processes are operating in your Mac.

The CPU is another possible factor that could cause slowness in your Mac. If you’re running a program that is using a lot of CPU, it’s best to stop it. Start Activity Monitor, click on the “X” button under the buttons. You can use Google to search for the programs that use excessive CPU power, if you don’t know what ones. It will give you some idea which applications are causing your Mac to run slowly.

If your hard drive is full this can cause the Mac to run slowly. Many applications use up the entire memory of your computer, which makes the operating system slow. Make sure to delete any files you don’t use or move them to another drive. If you’re not sure which is the issue, try opening the Activity catalina slow Monitor and looking at the complete list of processes that are running in your Mac. Some errors will be apparent – they are an indication that the Mac is running too many programs at once.
