I think the thing that was hardest for me to learn is navigating the folder systems. Luckily I can use a terminal.
Path Finder https://www.cocoatech.io/
ForkLift https://binarynights.com/
There are some shortcuts to make Finder usage more enjoyable:
- Shift+Command+H go to Home
- Command+Up go to parent folder
- Command+Down go in to selected folder
- Shift+Command+G go to written path
Also Option+Command+P toggles "Path Bar" at the bottom of the window
For that, Finder is maybe the one thing I miss from macOS. Haven't found one for Linux that works well and doesn't have surprising click/select/rename behaviour for example. (I'm using Elementary's 'Files' at the moment (not on its distro) certainly open to any suggestions.)
