I learned this trick when I misplaced the Leopard DVD that comes with the Macbook Pro. This time, I tried (with assurance from other blog/forum posts that it actually works – there are probably tons of more detailed tutorials than this.) doing the same for Snow Leopard.
What you need:
- External Hard Drive (USB or Firewire) –
WARNING: should not contain important files, since we will format this.
- Snow Leopard installer DVD or DMG file
Application to Use:
0. Create DMG file
Select the DVD drive from the Left Pane of Disk Utility. Then click “New Image” icon from the Top Menu. Type the filename of your choice (or retain as Mac OS X Server Install Disc) and the select destination folder and SAVE.

And so it happened to me… On a Saturday morning, I am the latest victim of the Macbook Pro Early 2008 bug. Apparently, according to Apple, it is a problem with NVIDIA GeForce 8600M GT graphics processor. In my case, it is more than a distorted video. Upon bootup, it shows these distorted lines at first, tries to load the OS, then stops with Apple’s own version of BSD (Black Screen of Death i call it) [see screenshots below]. Logic board fail.
The Apple Support website has THIS explanation:
In July 2008, NVIDIA publicly acknowledged a higher than normal failure rate for some of their graphics processors due to a packaging defect. At that same time, NVIDIA assured Apple that Mac computers with these graphics processors were not affected. However, after an Apple-led investigation, Apple has determined that some MacBook Pro computers with the NVIDIA GeForce 8600M GT graphics processor may be affected. If the NVIDIA graphics processor in your MacBook Pro has failed, or fails within three years of the original date of purchase, a repair will be done free of charge, even if your MacBook Pro is out of warranty.
Apple is issuing refunds to customers who may have paid for repairs related to this issue. Please contact Apple for details on the refund process.
