This question is just a sanity check. I wanted to factory reset a MacBook Pro (mid 2014) model. I first searched the standard tutorials and such, and have the core steps down:
- back up stuff
- log out of everything
- command + R on restart to get to the startup menu
- click disk utility
- click your partition
- erase and reformat (to macOS Extended or APFS)
- reinstall macOS (need internet for this)
In the myriad of tutorials for this there are a few images showing each process.
In particular when selecting one's partition it often has the little arrow drop down and the partition is not grey-ed out.
When going on this mac to the same screen, there is no arrow, it just has "Internal", then Macintosh HD (with no drop down arrow). This partition is greyed out, but I can still erase it...
Before doing so I just want to make sure that this isn't something abnormal.
