The CPU has been the heart of every PC since Intelâs x86 processors became popular over two decades ago. Yet the CPU does have weaknesses,the greatest of which is their relatively linear data execution. Graphics processors, by comparison, consist of many small cores that execute data simultaneously. This makes it easier for them to perform certain tasks, like video decoding and 3D graphics.
Solutions. 1  First try the normal methods to remove the disc. 2  Drag its icon to the Trash can in the Dock or select 'Eject' from the File menu. 3  If you are running a virtual machine, e.g. 4  VMFusion, ensure that the CD is disconnected from the virtual machine.
There is an Eject button on the Media Control panel. See Page 10 of the manual Here. If there is no disk activity and the button still doesn't work, contact Support. got a similar problem, but in my case, the cd won't eject even when I'm in BIOS/DOS/F8 menu. The only way to eject the cd is to use the EJECT function from My computer. The system is only 1 day old, and I encountered this problem only after few discs replacements. very frustrating.
