No I don't use externals at all besides tv's with thumb drive menus on it so that's simple and doesn't require other adapters. I also use Apple TV and will get the new one when it launches soon I hope. Maybe I'll even grab one for the store tv's. I also already have the hdmi, usb-c, usb-a female 3 port adapter Apple sells and it's not bad to carry I guess. But I just realized I will need to re-make the new menu of inventory for sale and different things I want my customers to see at my new shop opening soon; in photoshop. So that's just simple copy and paste of the brand names and logos of the brands I use and just simple text. I'm sure the rMB can handle that?
As for the programs. I will look it up. Thanks again!
That should be fine. If you're just editing something one time or once a while, the Macbook is perfect for it.
For people who like to edit hundreds or thousands of photos constantly, it takes CPU power and time to work through all those files. If it's just a few files, it doesn't matter.
Only those who like to capture all their pictures in RAW and then edit all of them into jpg just so they can get the right color (lol) they want, then those are people who would hate the Macbook.
