I have a 2020 MacBook Air which belongs to my employer. I want to back up my files (especially the excel files) and then remove everything on the Mac before I give it back. How do I go about this??
How do I back up my MacBook Air to an external source and then wipe it clean so when I turn it in nothing is on the computer. I am leaving my present job (under not good circumstances) and I do not want anyone to have access anything on this MacBook Air.
MacBook Air 13″, macOS 12.6
