I have a MacBook Pro 13" mid 2011... mechanically it very good. but High Sierra seems to be losing
stuff...
misplaced folders, does not reconize the DVD all the time... and other things..
So I thought I would reinstall 10.13.6.. first could not download from App store. could not find any way to install
from the net... I found a site with a full dmg.. so I downloaded it..
Now the question is how to reinstall onto my HD.. I placed the 5.1Gb dmg. in a very small partition that I had
only about 8GB ...
can I run the dmg from there?
