Upgrading from 10.6.8 to 10.8.x
After my 2008 Mac mini (10.6.8) died, I got a new i7 Mac mini with OS X 10.8.3 pre-installed. Was able to transfer my settings, documents and apps from Time Machine backup.
The only things that did not work anymore due to PowerPC code no longer being supported in 10.8.x were:
Eudora
MS Office 2004
Samsung ML-1710 printer driver
Here are my solutions:
Eudora -> Eudora OSE (Open Source Edition) based on Mozilla (https://wiki.mozilla.org/Eudora_OSE)
MS Office 2004 -> MS Office 2011 (thanks to my employers MS Home Use Program HUP)
Samsung ML-1710 printer driver - SpliX driver (http://guigo.us/mac/splix/)
So far so good.
I must say I am impressed with how well the transfer to the new machine worked.
I still have an issue with some of the recent photos in my iPhoto library not showing thumbnails and not being able to open them. Only the last 6 events though out of thousands of events. Tried rebuilding the database and library to no avail.
