For some reason my iMac won't accept CDs to burn. It sometimes rejected a CD but now it won't burn any, giving me the message that there was a "media error? I checked the systems info and it says the disc burner is OK.
iMac (21.5-inch, Late 2012), OS X Yosemite (10.10)
There can be numerous reasons, anything from a incompatible media (try different brands of media), to needing a simple SMC and PRAM reset, to a dirty laser which requires a CD/DVD cleaning kit to a worn SuperDrive. Start with the resets, if needed do the resets and if those don't work progress to changing media to finally getting the SuperDrive replaced.

It looks as if the Super Drive will have to be replaced. What a bummer! Thanks for the info though.
There's a "secret" about Super Drives: it may accept a certain type of drive early on in its life, but reject that same media later.
For example; you may need the AZO Verbatim instead of the standard Verbatim disks. Sony disks are consistently good on Super Drives. Give your Super Drive a cleaning, and try out other media. And please report your results here, so others can benefit from your research.
Why is my 2010 iMac not burning CDs anymore?
