LeopardAssist is a software application that helps install Mac OS X Leopard on systems that do not meet the 867 MHz CPU requirement. This software allows users to run the latest version of Mac OS X on older systems, opening up a world of possibility for Mac users.
Technically speaking, LeopardAssist writes a file named "boot.txt" to the root directory of your hard disk, and configures the NVRAM (PRAM) to boot from it. When you restart your machine, Open Firmware reads the file and changes the reported CPU speed before switching to CD or DVD and booting from it. The Leopard installer then takes over, making it possible to install the OS without modifying your DVD.
Once the installation is complete or ready to reboot, you can easily flash the PRAM back to restore the original CPU speed and boot from your hard disk. It's important to note that all effects of LeopardAssist can be reversed by flashing the PRAM as usual using Command (Apple) + Option + P + R and restarting your machine until you hear the second chime.
Overall, LeopardAssist is a reliable tool that can save you time and effort when installing Mac OS X Leopard on systems that don't meet the CPU requirement. However, it's important to exercise caution when using this tool, as it comes with some risks.
