Purchased a refurb iMac 27" about a month ago, it's my first Mac and I'm thrilled with it. I've come across an issue reading some old CDs I had lying around. They all contain photos or movie files and were created with the PC I replaced with the mac. I can read any other media with the mac (DVDs, CDs) but there are a handful of these CDs that when installed, will not read or be recognized by the optical drive and will just spin. Of course they then won't eject either .. fortunately I came across an article that had several tricks for removing stuck media. After trying terminal prompt commands and several other tricks, I booted while holding Option down and then was able to eject from boot screen. The only thing I can think of is that I may not have closed out the session after copying the files from the PC. Could that cause the Mac drive to hang up ? I'm happy to blame the media and not the drive, but annoying that there is not a hardware override to eject the disk, rather than doing a forced shut down and restart. Thanks for any advice.
