This post is all about how to fix your slow Mac with Activity Monitor, a free app that is built right into Lion. Your crawling Mac might be slowing down because of one particular misbehaving application, and Activity Monitor will identify and terminate the problem.
Here’s how to fix a slow Mac using Activity Monitor
1. Go to the Applications Folder and open the Utilities folder. Don’t forget you can type the letter “U” for Utilities while in the Applications window to jump right to the desired folder.
2. Inside the Utilities folder, you’ll find Activity Monitor. Launch it by double-clicking as you would to launch any other program.
3. The Activity Monitor shows all of the current processes and applications running on your Mac. Here’s where you want to search for the pesky application that is dominating your Mac’s processors. Sort Activity Monitor by the %CPU column by clicking on it twice to ensure the processes that are taking up the most space are showing at the top.
4. Here’s where you have to do some experimenting. It’s not always clear what’s taking up the most energy. Try closing different programs by clicking on it, and then clicking the Quit Process button. Here’s where you have to pick whether to “Quit” or “Force Quit”. Force Quitting isn’t always the best choice as it shuts everything down ASAP. So if you close down a Word document that has unsaved changes, it will be lost. But, Force Quitting will ensure everything shuts down right away. Just be aware of what may happen.
5. Done! Now you’re Mac should be running faster and it’s all thanks to Activity Monitor.
You can also set up Activity Monitor’s Dock Icon to turn into a live-updating chart that shows what’s going on in within your Mac in real time. Control-click, two-finger click, or right-click the icon, and select an option from the Dock Icon submenu. If you select something like Show CPU Usage, you can monitor to see if something is taking up too space on your Mac’s processors.
