So I upgraded to lion. I then tried to make a boot disk of lion, but the toast and disk utility reported problems burning to the disk I had in the drive. I assumed it was just the brand of disk, and still haven't got round to doing it. But then today my copy of ilife turned up (bought of ebay). Ive tried installing a number of times and had failures part way through installation every time. Its finally installing, but I don't hold much hope of it finishing, its saying 4 hours to install ilife, so it is working, but very very slowly!! Has anyone else had problems...... The disk seems to be read fine when I boot from my snow leopard disk. Ive already reset the ram. This is all happening on the mac pro in my signature, its the quad core intel xeon 2.8 ghz (early 2008) and the system profiler won't bring up the dvd drive model for me to post. Any help would be greatly appreciated, thanks. ---------- yip, its just failed again.
