My wife has a 2017 MBP and after upgrading her OS to Big Sur, the laptop has become dog slow. It takes literally seconds for a new program or browser tab to open. The OS should be called 'Big Slow'.
Anyway, I thought I might try erase her HD and reinstall the OS, but we have some concerns. We want to ONLY reinstall the OS. We do not want to lose any data and we do not want to have to reinstall any applications. She does regular Time Machine backups.
There are a lot of posts with the same question I have here, but for whatever reason, they all ignore the question about applications... so I am asking again.
- Will using the 'reinstall OS' option result in DATA being removed?
- Will using the 'reinstall OS' option result in APPLICATIONS being removed?
- Must we reinstall the OS and then restore from the Time Machine backup, or a simple 'reinstall OS' is enough?
