What is Mac OS 8.7 - 9.0 Betas? MacOS 8.7 is supposedly a cancelled MacOS 8.x update, that became MacOS 9 for PPC. As shown by Action Retro, it can be run on a PowerBook 540c that has a PPC upgrade inside, however, at least for him, the wallpaper becomes the "starting up" screen. It is annoying, but can be fixed until you restart again. 8.7 is very usable, but can be a struggle on PPC-upgraded 540c PowerBooks. It comes with lots of software (supposedly), and is great for people looking for the unreleased true final version of MacOS 8. Download Mac OS 8.7 - 9.0 Betas for Mac
