I don't know anything about mac computer.
I built myself a pc just 3 months ago,
I have a friend who love my Panasonic G7, which 4 K footage I can edit flawlessly with either Vegas or Resolve on my PC, who asked me if her imac would be up the task. I told her I had no idea, so I'm asking you guys:
That's what she has: iMac 2.5GHz Intel Core i5, 16 GB 13333 MHz DDR3 With an added Solid State Drive (capacity 119.17 GB with 40.12 GB available) Graphics AMD Radeon HD 6750M 512 MB
