Macbook pro ejects every CD/DVD just after a few seconds

Solution 1:

Try the following steps and I am sure it will be fixed.

1. Clean the SuperDrive’s slot with compressed gas/vacuum cleaner.

2. Reset the NVRAM/PRAM and SMC

   • Reset NVRAM and PRAM:
     Shut down the computer. Holding down the Command (Apple), Option, P, and R and then hold the Power button simultaneously, 3 times and wait for 3 loud chimes.

3. Delete the Finder’s preference files

   Some people have reported successfully fixing Optical CD/DVD Drive on Mac or SuperDrive issues by deleting the Finder’s preference files (don’t worry, the Finder will automatically make new ones). You’ll 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.

4. Run Disk Utility and Repair Disk Permissions

5. Delete the following configuration file to create a fresh copy

   ~/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

Solution 2:

This is how I fixed it. :) I tried resting it normally after it eventually registered, but it wouldn't stick. So obviously not a long term solution..

Solution 3:

This has happened to me a couple of times over the years, all I do is hold down the command key and the disc drive accepts it. I have an iMac (24-inch, Early 2009) running Yosemite 10.10.5

Solution 4:

Worth noting, this can happen if you insert the disk upside down
