A couple of questions. I'm one of those Mac end-users who does not know a lot about the tech specs..but knows I only use Mac for the the same reasons I'm guessing most do. Currently I'm on an I Mac (21inch) that is just prior to Thunderbolt. Suddenly, I'm in a new job, and creating a lot of graphics. I'm also going ot the UK for a bit, but am an American. My desktop is running hot and slowing down..mac says maybe its leaking for somewhere? (Specs are 3.06 GHz Intel Core i3 4 Gig 1333 Mhz Ram) I love it, its two years old, but I need better graphics, etc. So. Here are my questions. One. Will a new mac make the trip well and handle the change in wattage use without hurting it? Two. Whats the best way to take a 27 inch into the UK for fastest and safest transport? Three. If I don't get the 27inch desk..how does everyone feel about the 17 inch refurb Macbook Pro, or the 15 inch Retina display? The latter is expensive, less real estate (I'm 46, so I like to actually see what I'm working on and I've heard the retina is very pretty..but many things aren't spec ready for it) I know this is quite a bit of info I'm requesting, and some of it may seem silly for someone who has used Macs for 15 plus years, but the truth is..I use the Mac because its plug and go, lightning fast, beautiful, simple for someone like me and I have never had a virus, or shutdown.,knock wood. iphone, ipad, itouch macbook, IMac..all have been golden. (TBH, I can't understand why on earth anyone would want the other brand..but that's my 2 cents) so thanks for any and all help, in advance. I have used this forum for some time..watching it and referencing it, and I figured it was the best place for help. It's my first post, so please be kind.
