    Specs:
    15" MBP, Core i7/2GHz, 8GB RAM, 480GB Crucial M500 SSD
    I wouldn't spend a nickel on it, but the newest version of OS X is going to be 10.4, which is quite old now (originally released in 2005).

    Mac OS X 10.4: System requirements

    With that said, you will need a retail copy of 10.4, which can be hard to come by and very expensive. Even if you did manage to come by one, chances are it will run excruciatingly slow on a machine of that vintage, even with upgrades.
    Liquid and computers don't mix. It might seem simple, but we see an incredible amount of people post here about spills. Keep drinks and other liquids away from your expensive electronics!

    Specs:
    iMac i5 2.7GHz, 16GB memory, OS 10.10.5
    And expect to pay up to $100 for Tiger, and another hundred odd for the hdd and memory. Put it into a newer machine.
    Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    I can't believe an OS that old is still going for that much money. I just saw a retail Tiger disk for sale on my local craigslist for $20... Maybe I should buy it if it's that good a deal.

    If it is a full retail install it is dirt cheap but MacDude make sure it is not a silver/grey disc that is extremely model specific.

    At Amazon new version still brings $159.00:-

    Either it's not really retail Tiger, or the seller is clueless. All of the more modern versions of OS X that will still run on PPC are fetching higher prices. Tiger less so than Leopard, but still a lot of software runs on Tiger that won't run on older versions of OS X.

    You were right in saying that the seller was clueless. I gave him a call and he said he had no use for it, somebody gave it to him and he was just gonna throw it out if nobody bought it. I made sure it was the black retail disk, and picked it up for $20. It's still in the box, with all of the manuals and original paperwork. Can't wait to get it running on the G3.

    I pick up my disc at the thrift store for $2.00...you just have to know where to look.

    Also if you change the hard drive you may need to reinstall the firmware for that machine first before the os.
