On my white MacBook 2.2, when I plug the Apple Mini-DVI to DVI Adapter into the mini-DVI port, it snaps into place perfectly. You can hear an audible snap (a click), and it is snug. The fit is perfect. I purchased a new BlackBook 2.4, and when I plugged the Apple Mini-DVI to DVI Adapter, it never snapped into place. There was no audible snap, and it could be easily pulled out without much resistance. I returned the BlackBook and requested a new one, which is on the way. To any BlackBook users reading this who also happen to use the Apple Mini-DVI to DVI Adapter: Does the adapter snap into place when you plug it into the mini-DVI port on your BlackBook? Do you hear an audible snap (a click)? (Please specify if you are using a BlackBook 2.4 or another BlackBook.) Thank you to everyone who replies!
