Why won't my dvd work with Yosemite

Hi Philip,

If you're having issues with the optical drive on your iMac, then please see the troubleshooting in the article linked to below.

Which model iMac are you using?

Another help source (if you haven't already done so).

Go to your OS Help Menu. In the search field type dvd

Click on all the troubleshooting topics & Support Articles that pertain to your issue.

You can also do the same in Disk Utility. Open same up.

At the bottom left of the window, click on the purple button w/the "?" in the middle.

This will bring up the Help Menu.

Hi Philip,

As you can see from the article, it covers a multitude of issues that may occur with the optical drive. Which particular issue is your iMac experiencing? What exact troubleshooting have you done in the article already?

Thanks for using the Apple Support Communities!

Cheers,

I have 2 iMacs. Both worked fine until the Yosemite upgrade. Now neither dvd works. This is an Apple issue that they are not willing to admit on their failed rollout.

If you haven't done so yet, try installing Apple's SuperDrive Firmware Update 3.0, which is on Apple's support site at http://support.apple.com/en-gb/HT201953 to see if that might help, even though it's not specifically for that problem, it seems to be important for making external SuperDrives work in Yosemite, and it is one step I used to get my SuperDrive to work in a USB external case when plugged into my MacBook Pro.

Please let us know either way, whether the firmware update helps or not in your situation with your internal SuperDrive.

For anyone with an EXTERNAL SuperDrive that isn't working, this is what worked to fix mine so that it would play movies, although it already played data CDs, and I had already done the firmware update at that point:

External SuperDrive DVD player fix - RESOLVED!

This solution worked for my Superdrive, which I had installed in a USB external case, so now it can play movies using Apples DVD Player App, but additional steps may be needed, as I outline below. I had removed the SuperDrive from my mid-2009 Macbook Pro 15" 2.53 ghz to install a second hard drive with Other World Computing's "Data Doubler" adapter, and mounted the SuperDrive in an OWC Value Line SuperSlim external case.

I don't know if the first two steps below are necessary, but I had done them first, because others suggested them as fixes before I found the solution in the 3rd step.

1) I installed Apple's SuperDrive Firmware Update 3.0, which is on Apple's support site at http://support.apple.com/en-gb/HT201953

2) Then I applied a fix on this page, http://www.hardturm.ch/luz/2011/10/how-to-make-the-macbook-air-superdrive-work-w ith-any-mac/comment-page-12/#comment-106449, using Text Wrangler to edit the preference file at /Library/Preferences/SystemConfiguration/com.apple.Boot.plist by adding code mbasd=1 between the two string values. However, that still did not resolve the problem. I left the preference file with the code “mbasd=1″ included, as outlined on that site.

3) Then, I used the fix at http://macriot.com/mcrt/?p=2294 which requires modification of some code embedded into OS X’s DVDPlayback framework; essentially replacing the words “internal” with “external”

Now my external Superdrive plays movies using DVD Player. 🙂
