My husband and I bought the family edition of Leopard last night, along with iLife08. I installed iLife while he installed Leopard. No problems on either Mac. However, when I went to install Leopard, once I double clicked to start the install, it seems like my Mac won't "read" the disk. I get the spinning rainbow and there's lots of chugging sounds happening, but after almost an hour (yeah, I'm patient), it was pretty apparent that nothing was actually happening. I'm really perplexed...it's not a disk problem, as it installed fine on my husband's Macbook...and it's not a drive issue as iLife installed just fine a few minutes before trying Leopard. Any ideas??? TIA!
