    I just bought a mid-2011 27" iMac with 3.4 processor and original BTO 256 GB SSD w/ 1 TB HDD.

    This Mac currently has 10.9.5 on it, but I bought it specifically because it was the last and most powerful iMac which was made to run my preferred OS, 10.6.8.

    To that end, I purchased 2011 iMac 10.6.6 install disks, and proceeded to perform a clean install earlier this evening. I did not get very far, because it will not allow me to use the SSD as the destination disk for the install, warning me that this machine cannot boot up from the SSD, even though the SSD is the current startup disk, with the 10.9.5!

    Is this correct? Am I missing something here?

    How can I install 10.6.6 on the SSD (which I assume was the factory setup)?

    Thanks much

    Use Disk Utility to fully erase the SSD and then install on to it.
