@@ -6,3 +6,15 @@ A slightly more user-friendly front-end for using MAME as an Apple II emulator.
 
 
 A custom version of MAME is included (only apple 1/2/3 emulators are supported in the custom version).
+
+
+Ample release 10 MAME includes the Macintosh (NuBus) driver and UI support for configuring and launching some Macintosh models.
+Please note the following warning concerning MAME's Macintosh emulation: 
+
+Mac emulation is still in progress. While many features work, some are not in place yet, and others are a consequence of accurate Mac emulation.
+
+* 3.5" floppy support is a work in progress and currently only works with 400K/800K disks (to be fixed in the future)
+* Images selected in the “Hard Drives” section must have a full partition table with Mac drivers (this will always be the case)
+* "Hard Disk Images" (enabled with the NuBus Disk Image Pseudo-Card in a slot) can be used to mount standard HFS images without the need of a partition table or driver (this will always be the case)
