Greetings all! My name is Tim and I run global business, mastering in gaming, and a successful game call Day of Chaos. All our staff use Macs given to them by us, their own, we dont own them. I recently placed an order for 200 Macbook Pro's With 2.5Ghz, and 8GB of RAM to give to all them. Currently, we only have licenses for Leopard and Snow leopard. I understand the Macs come with Lion, but we can not migrate to Lion yet, as we have began testing Lion on our systems, but not ready for release to our company yet. Will the latest version of Snow Leopard work for the Macbook Pros? Here is the official specs: 2.5GHz Quad-core Intel Core i7 8GB 1333MHz DDR3 SDRAM - 2x2GB 750GB Serial ATA Drive @ 7400 8x Double-Layer SuperDrive MPB 15" Glossy WS Display Keyboard/Users Guide Country Kit Thank you for your time Mac lovers! EDIT: Success! It works perfectly! I got a hold of a early 2011 disk with 10.6.7 update (downloaded the .ISO from the web). Of course, trackpad was funky, keyboard top keys didnt work, and it thought I had a 13 inch Macbook Pro. But that was solved by installing 10.6.8 though software update. Everything works, just like normal! Keyboard, trackpad, everything, and I mean EVERYTHING works just like it was installed when it arrives. SL for the win!
