Yeo..question, i have an old iMac (all in one Mac desktop) from like 2010 or something like that so I'm having trouble downloading certain programs and using certain sites bc my operating system is outdated and i can't download the latest version of Mac's operating system, so I'm thinking of buying an external hard drive and updating my Mac thru that if it's possible, what do you guys think, what are some solutions? Bc my Mac runs perfectly fine, it's just an outdated version of Mac - should i buy a new one? Or is there another way around this?
