Here’s my notes on how I approached installing OSX 10.9 on my Late 2007 MacBook (MacBook3,1).

Note I did most of this on a current Mac running 10.9.

Also, this kind of worked. I got the install to run but it wouldn’t boot after install. I’m probably quite close to it working. I’ll update this post with notes if I work on this further.

Steps

1. Create USB Flash OSX 10.9 installer
2. Go to /Volumes/Install OS X Mavericks/Install OS X Mavericks.app/Contents/SharedSupport/
3. cp OSInstall.mpkg OSInstall.mpkg__ORIG
4. pkgutil –expand OSInstall.mpkg OSInstall
5. Find your board-id: oreg -l | grep board-id
6. edit /Volumes/Install\ OS\ X\ Mavericks/Install\ OS\ X\ Mavericks.app/Contents/SharedSupport/OSInstall/Distribution
7. Add your board-id to the platformSupportValues array in the Distribution file
8. pkgutil –flatten ./OSInstall ./OSInstall.mpkg
9. Edit the /Volumes/Install OS X Mavericks/System/Library/CoreServices file to also contain your board-id.
