Yes its 5 years old but its still a nice piece of gear.
32 g of memory an 5i processor and a slow hard drive.
I was running drop box - 120Gb
two google drive accounts 100gb each.
Zotero a bibliographic data base.
Scrivener 3 - Gimp photo editing. iThoughts and Xmind for mind maps.
Shotwell on parallels.
Mail and web browsers (Firefox).
Music thru itunes.
It took 10 minutes to wind up. Then it would grind away and low and behold if you wanted it to compile something or save it.
I realised my HP360 was running the same programs (functions) under Manjaro Mate so I tried that route with the imac. Manjaro and netrunner were tried.
Both were OK but lacked zest. Manjaro Cinnamon worked well.
So then I tried Mint Cinnamon 18.3. And yes everything work with a bit of zest.
Scrivener 3 (beta) is running fine in wine. Xmind works. and the rest all work in Linux.
And it does not run like a dead slug.
Copying data from my CarbonCopy Cloner backup is taking some time . Just sheer weight of data.
