I own an iMac that was recently updated in error by a family member (I've forgiven them). This was a disaster because some of my hardware and software no longer work! Previously this iMac was running Snow Leopard 10.6.8. So, I decided to install Snow Leopard again. I have the original disks (remember those things) that came with the computer but cannot install Snow Leopard. I have wasted two whole days on this and am now desperate.
My specs are:
- Late 2009 iMac
- 27" model
- 16GB RAM
- Apple Wireless Keyboard
- Magic Mouse
- Mac OS X 10.11.6 installed :(
What I have tried:
- Booting into Recovery Mode, from both the local HD and internet, but my Mac doesn't seem to support this?
- Installing Snow Leopard from original Apple iMac grey disks that shipped with the computer
- Installing Snow Leopard from a retail version of Snow Leopard (borrowed from a friend)
- Verified the optical drive is working fine (it reads CDs/DVDs and burns DVDs fine)
- Verified that booting from the optical drive is fine (booted from a Prosoft Data Rescue II CD)
- Followed the steps outlined at http://www.makeuseof.com/tag/upgrading-your-mac-to-snow-leopard-using-your-usb-drive/ to create a bootable installation USB. I did this in case there was some other issue with using the optical drive.
- Searched Google, Apple discussions and here for an answer
I am willing to try anything at this stage. I have a function on February 19 to prepare for and I require Snow Leopard for compatibility with some specialized software/hardware.
Pleeeeeeaaase can someone help me? Pretty please with sugar on top…!!! :)
