2015 Macbook Pro to M1/M2 Macbook Air - how much space to take Time Machine Back up on new one.
Guys
Might be a basic question but can't find help online. My 2015 Macbook Pro is almost full and it's time to upgrade anyway. Given I have c. 450gB of stuff on existing hard drive how much of that will be transferred and so how big does storage need to be on new Macbook? I use a Lacie 1tB external drive as time machine for the moment.
MacBook Pro 13″, macOS 11.6
