5 Ways to Solve a Mac Running Slow After macOS Sierra Upgrade

macOS Sierra running slow

Did you recently download macOS Sierra only to find your Mac is now crawling along? If macOS Sierra running slow is a problem for you we have 5 potential solutions.

Clean, Clean, Clean

We can’t emphasize this enough: you need to keep your Mac free of junk files. Although relatively small files individually, your Mac carries a lot of junk weight if you don’t maintain it. Every download comes with extras such as read-only files, alternative language files, icon files, etc. Programs such as CleanMyMac 3 identify and remove junk files for you. They do the work and you reap the rewards. Phew! We love CleanMyMac 3 as you can see from our reviews:

Reduce RAM Storage

Check which programs or applications eat up your memory by launching Activity Monitor > Memory. Remove programs or applications drawing larger chunks of memory that aren’t necessary.

Upgrade to the latest macOS Release

With each tweak, Apple includes bug fixes, many of which might contribute to your slow running Mac. With macOS Sierra 10.12.3 Apple fixed a Safari bug that made your web browsing experience on Safari seem slower than usual.

Conduct a PRAM Reset

  • Shut down your MacBook Air
  • Wait till all processes are closed and the MacBook Air is completely shut down (off)
  • Press the Power button and the following buttons IMMEDIATELY after pressing the Power button: Command + Option + P + R
  • If you pressed the above sequence correctly, you would have heard a two tone startup sound
  • Your PRAM reset is complete

Investigate Mac’s Spinning Rainbow Wheel Immediately

Are you frequently seeing Mac’s spinning rainbow wheel? Take care of that problem now. It’s indicative of larger issues.

  • Force quit the offending program. Whichever program you know or suspect to be malfunctioning (often the one you were most recently working in) needs to be closed. To force quit a program you can either, 1) go to the Apple menu in your menu bar and select “Force Quit” from about halfway down the menu, 2) right click (or Control + Click) on the program and select “Force Quit,” or 3) press Command + Option + Esc.
  • Reboot your computer. You can do this by holding down the power key on your keyboard.
  • Reboot your computer in safe mode. Once you hear your computer start with the “dawning of the morning” sound, press + hold Shift. Let go when you see the Apple logo. In safe mode your Mac will look for system issues. If nothing happens after a bit of use then you’re good to go. Shut down your computer and restart as normal. If Mac goes haywire in safe mode then get your computer to Apple Support stat.
  • Re-install your operating system. You may need a fresh start and to make sure things are installed properly before going to Apple Support.
