I have been using a pair of older Dell Lattitudes. (E6530, E6430, both with quad i7's.)
The only real drawback is the native video card does not directly support 4K. (I can get 4K with a custom resolution @ 30, refresh rate.
In the US, a good cond, used unit is only $2-300.00. Add a ssd and replace the optical bay with a 2nd hard drive adapter. With the older style dell dock, I am able to drive 3 monitors, 4 using the notebook screen.
In an earlier life, I was one of the Mac's biggest fans. Apple's migration to a social media based operation system and OS updates made it impossible to use as a graphics machine.
Back in the 90's I ran Photoshop v3, on a power pc mac. When they nixed all software that ran on 10.6 and earlier, I abandoned ship with pleasure.
Instead of a Macbook Pro, you can you can use the same money on a used, fast PC, and a refurbished or new Nikon Df.
Just my $.02.
