I have a mid-2007 iMac currently running Mavericks. It originally ran OS X 10.4 Tiger. Is it possible to run Internet recovery or use some other method to restore it back to OS X 10.4 Tiger?
Clickhereand follow the instructions. When you reach step 5, insert its original disk, restart with the C or Option key held down, use the Disk Utility to erase the internal drive, and install a fresh OS.
