Why is my Mac Air so slow?

Episode 1636

Mark from Tustin, CA

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 terminal. That could speed it up.

Ray wants to know how he can update macOS without an internet connection? He has more than one computer and doesn't want to download the update more than once. Leo says that you can copy the installer and then use it on the other computer if you do it within an hour or two. It'll be up to date. What happens when a patch has multiple versions? Leo says that sometimes Apple slipstreams a fix into an existing patch, and users end up with two different versions. That can be confusing. But go with the most recent one.

Episode 1568

Dan from New Jersey

Dan is shopping for a MacBook Air for his son's trip to China. but when you add more RAM, it's more than the MacBook Pro. So should he get a MacBook Pro instead?

Especially since it offers more storage for $500 less. It has the older butterfly keyboard, however, which could cause problems if eating while working. SO make sure to buy AppleCare plus.

Episode 1560

Jack from Garden Grove, CA

Jack's iMac runs El Capitan, and his iMovie and Garage Band have stopped working. He has been told he has to upgrade to get them working back. But he's hesitant. Leo says that it's OK and you should upgrade. Apple isn't like Windows. You can safely go to Mojave, or at least High Sierra. Why did your apps stop working? That's a puzzle. Maybe your graphics card is too old? Or Apple may have just broken the connectivity. Upgrading to Mojave though is important for security reasons.
