Hi, I have a 17" iMac 2104 (intel) The hard drive died and thus I purchased a 2tb Seagate Barracuda. I'm assuming that this will operate with the iMac, but I was never able to find any proper details saying whether it was or was not. Secondly, I do not have the OS X Tiger installation CD, and I was curious if there's a way for me to download it and install from Apple. Seeing as I do own the iMac, I should have the license for the OS as well. (Much like how my macbook pro was able to just do a internet recovery of OS X Lion. Please let me know!
