I'm using a late 2013 rMBP I bought brand new when it came out. Five years into daily usage and I haven't had a single issue. The specs are: 2.8 GHz Intel Core i7, 16 GB 1600 MHz DDR3, and a 500 GB HD. I am a 35mm film photographer and all I've used this for is scanning with my film scanner and editing in Lightroom. I bought a Thunderbolt display on eBay and after a few hours it flickered a few times and I immediately contacted the seller to return it. He had a temper tantrum but I was able to send it back. Have a feeling he's going to try and pull some shady **** though. Lesson learned: never buy things like Apple computers from a power seller who only sells baseball cards, golf clubs, jerseys etc. I got a different Thunderbolt from a graphic designer. It is in MINT condition and works perfectly. I got a magic keyboard and mouse and my setup rules. But here is where my dilemma starts: I used to be a photo retoucher but I could not handle doing that 40 hours a week in a dark creative suite so I quit to start bartending again. I am pretty sure I can get a good amount of freelance work but I don't think my laptop is going to be able to handle MASSIVE files. If that's the case, I'm going to go into top ramen mode and try to get a new computer. I am torn between getting a new MacBook Pro or an iMac Pro but am leaning towards the iMac as you get way more bang for your buck. But then again, the laptop and 27" display is such a rad combination since it is essentially a desktop and laptop in one. Would it be weird to pair an iMac or MacBook with a TB display? I mean, just because the iMac displays are incredible, it doesn't mean the TBs are all a sudden ******, right? And if my laptop ends up not being suited for the work, what should I go for in terms of specs?
