I'm a newbie on the Mac world and I'd like to know if it's possible to cut a file using a shortcut (like Ctrl+X on Windows).
It is possible to cut-paste files/folders in Mac OS X 10.7 (Lion)’s Finder (so, since at least 2011), but the Mac OS X way is slightly different from the Windows way. This method works in other versions of Mac OS X as well.
So, the steps are very similar to copy-paste, but holding ⌥ (option key) moves the file/folder instead of copies it.
You can also have a look in the edit menu after copying a file - press ⌥ while looking to see the difference: “paste” changes to “move item here.”
I like XtraFinder
It's an enhanced version of Finder. You get Cut & Paste and a bunch of other features.
And it's free.
