I recently purchased a used Mac after going to PC 14 years ago. My last good experience was with OS 9. I have a dated iMac with a Core 2 Duo processor and recently upgraded from 10.6 to 10.7 which is the newest release I can use on this hardware.
What I am now having an issue with is that I can no longer backup to a shared drive on my Windows 2008 server. When this Mac was running 10.6 there were no issues, but since the upgrade I've read (link below) that Time Machine will only backup to a Mac server. Is this now the case with OS versions 10.7 and above?
