For anyone who likes to give their old first generation MacBook a second life past the Snow Leopard support date. Why? Windows 8.x is supported with patches until 10 january 2023 . The MacBook1,1 meets the Windows 8 system requirements. Video seems to play much smoother than on Snow Leopard, and having dedicated apps for e.g. Netflix might help too. The fan remains to be rather noisy of course, and there's the annoying coil whine. Can't do any magic hardware changes. Battery life Battery life is pretty decent, some estimates: * 1h40m when playing Netflix, automatic streaming quality 3000 kbps (720p) * 2h30m with youtube music running in the background in desktop IE11. * 4 hours when just browsing. About the same as Snow Leopard (which seems worse than I remember from Tiger days) Not supported by Apple You could just install Bootcamp 3 from the Snow Leopard DVD, and most will work. But Windows will bluescreen often due a buggy KeyAgent.sys made by Apple. That driver doesn't pass Windows' Driver Verifier tests at all. So you will probably want to uninstall Bootcamp. Quick howto Install Windows 7, from within Windows install Windows 8.1. Download all the files, run setup.bat as administrator. Wait a while. Reboot. Run load.bat in the dsdt-fixes directory as administrator. Brightness and battery charge status will now also work. Remaining nitpicks * Volume and brightness buttons don't work.
