Nice rundown 👌 I currently have a 2016 MacBook that works totally fine for Sketch and Atom. Adobe programs would probably be too heavy, but for what I do, the MacBook is totally fine, and super portable. I also have a 2012 Mac Mini that’s beefed up and can handle a lot more than the MacBook can, if I need something stronger.
I recommend Path Finder by Cocoatech. It’s a Finder replacement with a drag-n-drop clipboard, tabs and columns in windows, right-click menu customization, color customization (I like dark interfaces), dev tools, and much more. Try it out.
