I have an older Mac. The About this Mac says Mac OS X Version 10.6.8; Processor 2.16 GHz Intel Core 2 Duo; Memory 2 GB 667 DDR2 SDRAM. I know how old this is, but it suits my needs just fine... right up until my printer broke. I found a printer comparable to what I had, but it says I have to have at least OSX 7. I tried ordering a CD of Lion, twice, and both times it didn't work. I'm wondering if this Mac is too old to be upgraded; or the CDs were just bad. Can anybody help?
