There are many good reasons you might consider doing a clean install on your Mac. Perhaps it has gotten sluggish over the years, you may have had a hard drive replaced which necessitates the process, or you'd like to have as close to a stock operating system as possible before installing the next major release of macOS.

But performing a clean install (some call it a "nuke and pave") may seem like a daunting task, one you may be reluctant to take on. In this week's show, Allison talks about all the reasons why you might want to do it, suggests some strategies to attacking the task, and then shows the process in action. The full tutorial covers:
