NOTE: Project 081 is no longer being worked on. I know this may be disappointing for some of you, but I do not have time to maintain a project I do not use, and a project which is never going to be perfect anyway. I am going to keep the project up for anyone who wants to use it, but I will not be providing support to anyone requesting it.
Project 081 is a simple to use unofficial Mac OS X modification which can install Tiger on some specific models. (see support below)
- Close to vanilla experience without days of tinkering
- Many different patched drivers to get more things functional
- No bootloader needed before and after installation
- One disk image, works on both supported and unsupported Macs (doesn't install unnecessary patches)
On any version of Mac OS X, installed or recovery, open the terminal and run sysctl hw.model
It should report back one of the following:
- iMac8,1
- MacPro3,1
- XServe2,1
- MacBook3,1
- MacBook4,1
- MacBookPro4,1
- MacBookAir1,1
If it's not one of these, it's either too new or natively supported.
- MacBookPro4,1 users: Fails to boot the installer, see issue #3
- MacBookAir1,1, MacBook3,1, MacBook4,1, XServe2,1: No GPU Acceleration which may cause minor slowdown with GPU heavy tasks.
- iMac8,1, maybe MacBookPro4,1: Installing the AirPort 2010 update breaks ethernet and wireless.
Nope, nope. Wrong place for that.

The goal is to make everything as free as possible. However due to Apple's full operating system being absolutely proprietary, there is no source code for Mac OS X Tiger to speak of.
