I have acquired the install/restore discs for 10.4.7 Intel and that shipped with the Late 2006 (manufactured in 2007) Mac mini. It's two DVDs: one 4.28 GB and the other 7.6GB.
Unfortunately, that means it's going to be very difficult to upload the .dmg files in one, much less segment them and then upload them. Drop DMG takes forever to segment them and then encode them as .bzip2 files; I waited for more than 3 hours and it wasn't even close to 1/4 finished. I just don't have that kind of time to waste on something so slow.
Does anyone have any brilliant, really fast ways to segment and compress these so they can be uploaded relatively fast, or is it not worth it to upload them to any file sharing site?
