Hi. I wanted to know the "user opinion" on the problem i have. I have a 2012 Macmini 2.5Ghz i5 / 4Gb ram / AMD / running with Lion, i wanted to upgrade to ML right after it come out of the box but i couldn't due some issues in the apple's payment method available on my zone. anyway once Mavericks was announced free i wanted to upgrade but i was forced to stay away from it because i needed some obsolete programs (like QuarkXpress among others) to keep up with my job So... 3 years later LOL after seen that apple doesn't want anyone get any other OS other than ML or ElCapitan what do you guys recommend me to do? The Apple tech/salesman/janitor told me that any version after mavericks its basically the same in performance and system requirements ...but im not really believing this. I could get ML for 20 bucks and keep iit up like that or jump into the latest version for free (and upgrade the adobe CC and other things) ...or try to fight my way to get Mavericks from the Appstore of one of the co-worker computers (as i hear this can be done) What do you think? thanks.
