- Ok, so this is a known problem. Instead of using the image provided by virtualbox you should just download it trough aptitute sudo apt-get install virtualbox-guest-dkms and if you need the headers download this sudo apt-get install linux-headers-virtual instead of the classic sudo apt-get install linux-headers-$(uname -r).

Notes:
I get the same error if the openSUSE installation DVD with iso image is in the iMac DVD drive or not.
I was able to Install Guest Additions with no problems on the same iMac and VirtualBox with Fedora 18.

A very easy way that I discovered to fix VERRPDMMEDIALOCKED for guest additions with a ubuntu guest and windows 10 host is: Shut down (not save state) your virtualbox; Right-click on your machine in the virtualbox manager - settings; Click on storage; Right-click on the cd drive and 'remove attachment'.
