Why is my Mac Air so slow?

Episode 1636 (30:21)

Mark from Tustin, CA
Macbook Air

Mark's Mac Air is slowing down and he wants to know if there's an app like SpinRite that can run them. Leo says that sold state drives (SSDs) use TRIM, or wear leveling to keep your SSD in good shape.  It doesn't need to be defragged directly. But it will trigger the controller to run the TRIM utility. Search for TRIM in macOS. But it should happen automatically. If your OS is older though, you may need a third-party app to do it. 

TRIMFORCE Enable is the command you can use in the terminal. That could speed it up.
