Thanks for that. What would you advise as a minimum spec pleaseIf you get a cheap/old/slow one you'll just end up jumping up and down on it with frustration. That is unless you work as slow as the processor is.
Capture One is better at tethering than Lightroom as it's faster (as you may know). If you combine a slow processor and limited RAM with LR it will be as slow as a slow thing swimming in molasses.
I'd never touch anything made by Apple - sorry (ex electronics computer engineer).
