I just purchased my first Mac computer. Always was a PC guy, but I wanted to try this for my photography. I bought the top model with 512gb SSD. I know it’s all relative to what programs you want to run and new programs coming out. I plan on using photoshop and Lightroom that’s about it. That’s all my pc really has but it is getting slower. Had it about 3 years. For the price I’m hoping I can go quite a bit longer on the Mac, so that leads me too my question of how long has yours lasted you and have you noticed a significant slow down over the years with new programs and updates coming out for software?
