@@ -119,8 +119,6 @@ The following input modes are available:
  !> Using the _Unicode Hex Input_ input source may disable some Option-based shortcuts, such as Option+Left and Option+Right.
-  !> `UC_OSX` is a deprecated alias of `UC_MAC` that will be removed in future versions of QMK. All new keymaps should use `UC_MAC`.
 * **`UC_LNX`**: Linux built-in IBus Unicode input. Supports code points up to `0x10FFFF` (all possible code points).
  Enabled by default and works almost anywhere on IBus-enabled distros. Without IBus, this mode works under GTK apps, but rarely anywhere else.
