This is a sampling CD-ROM from AMG, "Coldcut Kleptomania," a collection of sound materials created by Coldcut. REX/RCY/WAV/AIFF/AUDIO I have confirmed that it can be read on a Mac, but it seems that the data portion cannot be read unless the OS is an older version, as the Mac OS is not compatible. Audio can be read on any OS. I was able to read everything on Windows 11. Please understand that this is a used item before purchasing.
