Steps to install

  • Take a full backup of all your important data. Save it to the cloud or an external drive

  • Download the macOS Catalina installation file using this link
  • Turn off the Mac and then insert the bootable USB drive
  • Now turn the Mac back on while holding the Option key
  • It will take you to the boot menu where you can select the USB drive. If your Mac has the T2 security chip, you have to first enable booting via external drives from macOS Recovery
  • After a while, you’ll see the macOS Utilities menu on the screen. Select Disk Utility and then Continue
  • Check to make sure you’ve selected the main drive of your Mac. Also ensure that the format is set as APFS or Mac OS Extended
  • Now click Erase to wipe out the drive
  • Once the drive has been erased, select Install macOS and then Continue. Just follow the on-screen prompts to clean install macOS Catalina

Once you’ve successfully installed the new software, you can transfer all your data back from the cloud or external storage drive to the Mac. Also, head over to the Mac App Store and re-install all the apps you want.
