If your Mac Studio machine is having software issues, you might need to reinstall macOS, the operating system on your Mac. If you're ready to sell or give away your Mac Studio desktop, you might also need to reinstall macOS to erase your private data.
The macOS Recovery mode that Apple includes in its Macs makes it incredibly simple to reinstall macOS. That implies that you don’t have to be an expert computer user to do the task.
Below, we’ll outline exactly what you need to accomplish.
What Happens When You Reinstall macOS?
Every line of code for the operating system on your Mac is updated when you reinstall macOS. This is a great technique to remedy software defects since it replaces the destructive code that led to the bugs with good code.
Reinstalling macOS often doesn't alter the version of the operating system already installed on your Mac; instead, it just installs that version anew from scratch.
But we'll also teach you how to update to the most recent available version of macOS or reinstall the version that came with your Mac.
Reinstalling macOS shouldn't remove any content from your Mac, but there is no guarantee. After reinstalling macOS, your papers, emails, images, music, and other items should remain.

You won't be able to use your Mac during this time, which could take anywhere from 30 minutes to several hours, depending on several factors. When you're ready, reinstall macOS on your Mac using the methods listed below. These techniques allow you to reinstall your computer's most recent version of macOS.
