Cutting and pasting files
It is possible to cut-paste files/folders in OSX 10.7 Lion's Finder (so, since 2011), but the OSX way is slightly different from the Windows way.


⌘-C (copy first)
⌘-⌥-V (now move to it's destination)


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".
