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.

But SuperDrive does not always work with Windows PC right away however, and sometimes the Apple SuperDrive either doesn’t function as expected, won’t accept a disc, or is not properly recognized in Windows, whether running natively on PC, or a Mac through Boot Camp, or a virtual machine either.

What to do if CD / DVD Drive on my Mac keeps ejecting every CD / DVD 1.

Run Disk Utility and Repair Disk Permission Before starting any troubleshooting, I would recommend you to repair disk permissions as it solves hundreds of problems. A permission allows one application to “talk” with another application and so OS X wants permissions and ownership to be accurate and enabled to function properly. Sometimes these permissions on system files differ from what it should be and this is what we repair using Disk Utility. Disk Utility lets you verify and repair Mac OS X disks and permissions issues.To repair Disk permissions follow the below mentioned steps.

If you are using new macOS Sierra then read the post on and how to fix error found by disk utility in recovery mode. 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.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 don’t worry about it if it isn’t there. Restart your Mac after you do this so OS X will rebuild some of the files. Canon print drivers for mac.

3. Reset the NVRAM/PRAM and SMC A small amount of your computer’s 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 you’re 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.
