Installing a new macOS is a good all-purpose fix to any software problem on a Mac.


At the risk of sounding like a cheesy infomercial announcer… but has your macOS ever continuously repeat the same errors? Are certain types of software always running improperly? Does your MacBook run slow for seemingly no reason? What about something completely different, like selling your MacBook?

What is the answer to these hypothetical questions? Why installing a fresh macOS, of course!

Aside from resetting the PRAM or SMC, an excellent catch-all solution to most issues on an Apple computer is installing a new macOS. It solves the above cases (and many more). The best part about reinstalling macOS is there is no need to download anything extra to do it.

Looking to sell your MacBook soon and want to make it feel brand new? Follow the steps below to reinstall a new macOS easily.

A Mac user should be noted that reinstalling a macOS will require a few things to get started:

  • The first step in this process is going to be different depending on your MacBook model. So, figure out if your device has a silicon processor (the MacBook Pros or Airs with the M1 processor, for example) or an Intel one (any MacBook manufactured before the year 2020).
  • Make sure to have a backup of your current system, either through Time Machine or stored on an external drive of some sort.
  • Lastly, double-check your Internet connection.

After a user connects to Wi-Fi, gets their system backed up, and figures out which MacBook they have, it is time to move forward.

  1. Put your MacBook into macOS Recovery Mode:
  • If you own a MacBook with a silicon processor, shut down your computer by clicking on the Apple icon and selecting Shut Down. After the device boots down, press and hold the power button until the phrase “Loading startup options” appears on the screen. Click on Options, then Continue, and proceed with the onscreen instructions.
  • For those who own a MacBook with an Intel processor, restart the device. As the machine starts to boot up again, hold down Command and R when the spinning globe appears on the screen.

2. While in the Recovery menu, click on Disk Utility and then on the Continue button.

3. In the Disk Utility menu, click on View and then Show All Devices.

4. On the left-hand menu, choose whichever startup disk you are currently using.

5. After a disk is selected, click on the Erase tab on the bottom.

6. Once the disk has finished erasing, click on the Quit Disk Utility tab to exit, which will bring you back to the Recovery window.

7. Back at the Recovery window, select “Reinstall macOS” and follow the onscreen instructions to start the reinstall process.

It feels brand new!

Next time your MacBook feels slow or if the system is crashing all the time, don’t get frustrated. All it needs is a new macOS to be installed. However, any Mac user should know that it should not be the only solution to their problems. Constantly installing and reinstalling your macOS could cause additional problems.
