I’ve just installed Snow Leopard (OS X 10.6) on my Unibody 13.3” MB. Everything works perfectly fine. What I did step by step:
- Updated Time Machine backup (on external USB 2.0 HDD).
- Booted from Snow Leopard retail ($29) installation disk (I had to hold “C” key during boot to force boot from DVD)
- Ran Disk Utility (from Utilities menu) and erased my Macintosh HD partition.
- Ran standard installation on clean partition.
- Created user
- Installed X11 and XCode from installation DVD.
- Installed iLife from my Leopard 10.5 installation DVD (bundled with my MB).
- Updated everything to recent version (I’m still stuck with iLife 2008).
- Installed software that I use (mainly VMware Fusion, Textmate, Transmit, NeoOffice and macports stuff).
- Ran Migration Assistant and restored my user and system settings (without applications) from my Time Machine backup.
- Removed user
Everything works 2x faster. VMWare Fusion works with my 64-bit guest systems. iPhone syncs ok. So I’m up and running in about 3 hours. I don’t know is it Snow Leopard or system reinstall, but it was worth it :)
