Upgrading a 2014 Mac mini to SSD
Went fairly smoothly after watching several videos many times, i gathered the courage to upgrade a hard drive that was going very slow. Overall, it went well with very minor bumps along the way (clip popped out etc...).
You will never know unless you do. Having the correct tools also mitigates screwing up.
