CD DVD Drive on my Mac keeps ejecting my CD DVD
CD DVD Drive on my Mac keeps ejecting my CD DVD
CD / DVD Drive on my Mac keeps ejecting every CD / DVD
My CD/ DVD drive on my iMac is going crazy. Soon after I put a CD or DVD in the drive, it spits it back out. it sounds as though it is trying to read the disc, but fails. My drive was working normal earlier today, then it went crazy.I thought its my CD / DVD drive which is faulty and needs to be replaced so I plugged in a USB CD / DVD drive to my Mac that I had purchased long time ago.When I inserted any DVD in the external CD / DVD drive it did the same thing- ejected it.It keeps ejecting the CD / DVD automatically.Then I thought it must be a software problem so I did a research and found various troubleshooting steps to fix it.I am going to share the complete troubleshooting for this "CD / DVD keeps ejecting on Mac" issue which could be result of various reason like dust on lens,OS X issue, hardware fault.
1. Clean the SuperDrives slot with compressed gas/ Vaccum Cleaner
Your CD / DVD drive on your Mac might have got dust in its lens so clean the dust out. I bought this air duster Ecola Vacuum Cleaner ( for Keyboard,Notebook,Computer,Car etc. Compressed Air Duster ) just for $15 from Amazon, It can vacuum out dust and dirt from the chink of the keypad of calculator,telephone,computer,car and so on so give it a good spray into the CD / DVD drive slot on your Mac and this will resolve the problem.To do this first Shutdown your computer and get a can of compressed air. Place the tip of the nozzle attachement where it is aiming inside the drive and give it a couple of quick blasts to blow out any dust particles that may be causing you issue. Power up the system and give it another try.
I found this working for one of my customers once.

2. Reset the NVRAM/PRAM and SMC
A small amount of your computers memory, called non-volatile random-access memory or NVRAM, stores certain settings in a location that OS X can access quickly. The settings that are stored in NVRAM depend on the type of Mac youre using, and the types of devices connected to it.
Power related settings can be controlled by the System Management Controller (SMC) on your Mac. If you are experiencing issues with powering on your computer, sleep, wake, charging your Mac notebook battery, or other power-related symptoms, you might need to reset the SMC instead.
you can find reset instructions for both here:
Reset NVRAM and PRAM. - Shut down the computer.
Holding down the Command(Apple), Option, P, and R and then hold the Power button simultaneously, and told me to do that 3 times and wait for 3 loud buzzing (or some odd sound I cant describe).
Resetting the System Management Controller (SMC).
3. Delete the Finders preference files
Some people have reported successfully fixing Optical CD/DVD Drive on Mac or SuperDrive issues by deleting the Finders preference files (dont worry, the Finder will automatically make new ones). Youll want to delete two files: com.apple.finder.plist and com.apple.sidebarlists.plist. Both of these files are located in Users > [Your User] > Library > Preferences. You can choose whether you want to move the files to a new location (or simply append .old or something similar to the file names) or delete them, either way should work. Once youve deleted both preference files ("Com.apple.finder.plist.sidebarlists one might not exist, that isnt necessarily a problem), youll need to relaunch Finder. You can accomplish this by restarting your Mac or by bringing up the force quit menu with Command + Option + Esc (if you go this route, simply select Finder and click Relaunch.
Didnt fix your issue? Try 4.
4. Run Disk Utility and Repair Disk Permission
Disk Utility lets you verify and repair Mac OS X disks and permissions issues.To repair Disk permissions follow the below mentioned steps.
- Choose Go > Utilities.
- Double-click Disk Utility.
- Select the volume in the left pane for which you want to repair permissions.
- Click the First Aid tab.
- Select the volume to which you want to install the Adobe application, and then click Repair Disk Permissions.

5. Delete the following configuration file to create a fresh copy
Your Mac store the information of the every CD you put into the CD / DVD drive in a file called CD Info.cidb.Similarly some other files contains info about the settings and configuration of the drive and disk.Deleting them will allow OS X to create a fresh copy of them.Delete the following files from your Mac.
- ~/Library/Caches (your local Library directory).
- System/Library/extensions.kextcache.
- /System/Library/Extensions.mkext.
- /System/Library/Caches/com.apple.kernelcaches (a directory).
- /System/Library/Caches/com.apple.romextensions (a directory).
- CD Info.cidb (from ~Home/Library/Preferences).
Some of the files or directory might not exist on your Mac so dont worry about it if it isnt there. Restart your Mac after you do this so OS X will rebuild some of the files.
Note: - If the CD/DVD in your optical disk drive or SuperDrive has stuck in the tray then follow the steps mentioned here http://bookingtohosting.blogspot.com/2015/08/my-mac-computer-doesnt-eject-discs-or.html to eject it.
