Re: On the subject of slowing things down...
Um, I have a macbook pro, and installed Mojave in December. Speed is still perfectly good, but some other things broke. Cut&paste has become a nightmare, as it takes a bolshie attitude to what I try and select, and does dumb things like trying to open a dictionary on a selected[1] word. And LibreOffice broke badly: it keeps hanging and crashing. Round tuits permitting, I shall have to try uninstall/reinstall, or maybe switch to OpenOffice.
I think mine is more recent than 2012, but it may very well be the 2012 model, as it was an old model just being discontinued when I bought it in about 2016-ish.
