Mac Reformat Tutorial

A Mac reformat on average takes about an hour to complete and is fairly straightforward.

I’ve created a video demonstrating the process of what it typically looks like, narrating it as I completed each step that can be found Here

Some things to be mindful of are:

  1. Ensure that the computer NEEDS a reformat. If we can mitigate the time and hassle of backing up client data, we should definitely try to do basic troubleshooting first. I.e:( Checking drivers, checking for updates, checking issue forums online for particular problem.)  A reformat shouldn’t be a universal solution to basic computer troubleshooting ask an advanced or lead for suggestions or information.
  2.  It is crucial that we perform the Smart Test through Ubuntu or Solus.
    • The test is good for two reasons:
      1. Ensures the hard drive is in a good state for a reformat so that it can successfully install the operating system.
      2. If the client is complaining that the computer is running slow, it could be that the hard drive is failing making it a hardware issue and not a corrupt operating system, the smart test will help you understand this distinction.
  3. Note that any MacOS prior to High Sierra will require you to format the hard drive as Mac OS Extended (Journaled) whereas High Sierra and above strictly use APFS
  4. Quick command key for spotlight search is Command key + Space bar. Use the spotlight search as much as possible as it enables quick navigation through the local disk.
  5. When booting into a USB for Macs, you’ll want to launch the bootloader by holding down the option key as soon as you turn on the computer. Hold it down until you get a list of options to boot into, and select the USB accordingly.
  6. If you have any questions on any of the procedures or the steps listed above, kindly seek out an Advanced or Lead for help.
