Mac OS X 10.5 Leopard
Supported hardware
Installation on unsupported G4 hardware
1. Leopard Assist
For easy installation of Leopard on some unsupported G4s (<867Mhz), try Leopard Assist.
2. Manual method
Leopard can run on any older Macs that have a G4 processor and AGP-based graphics, so the "Sawtooth" Power Mac G4 onwards, simply by circumventing the 867 MHz processor speed check. This can be done either by modifying the OSinstall.mpkg file on the Leopard DVD to make a DVD that will install on any suitable Mac as it if were supported (when burning the DVD, if using a singe-layer disc delete the Xcode Tools package from the Optional Installs folder on the root of the image, as well as the packages in /System/Installation/Packages for all of the printer drivers and all of the foreign languages packs (do not delete AsianLanguageSupport.pkg though, this is not a language pack and will cause the installation to fail if it is not present), or by using an unmodified DVD and running one of the following commands in Open Firmware to temporarily (until next reboot) fake a supported CPU speed:
(1) Hold the Command, Option, O and F keys together when starting the Mac and only release them once the Open Firmware command line has appeared.
(2) Insert the unmodified Leopard DVD into the Mac’s DVD drive.
(3) Run the following script exactly as below (including capitals), press Enter after each line and check that Open Firmware displays "ok" :

Installation on G4 Yikes! and upgraded Beige & Blue & White G3s
Leopard can also be made to run on older non-AGP Macs that have a G4 processor (the "Yikes!" Power Mac G4) or that have been upgraded to a G4 (Power Mac G3 "beige" and "blue and white", older Power Macs, etc) but this also requires the addition of further kexts and installation using another Mac as the Leopard DVD will not be bootable.
Leopard cannot run on a G3 processor (not even the 900 MHz iBook G3 models even though they exceed the minimum 867 MHz requirement) as Apple only compiled Leopard for AltiVec, which the G3 line of processors does not include.
As of Mid 2010, some Apple computers have firmware factory installed which will no longer allow installation of Mac OS X Leopard. These computers only allow installation of Mac OS X Snow Leopard.
ATI Rage 128 and ATI Rage Pro graphics cards/chips:
Apple removed the drivers for these from Leopard so it will run on them but with no graphics acceleration. The Tiger kexts for them can be added back - download link in thread https://forums.macrumors.com/threads/tip-ati-rage-128-in-leopard.1691634, after placing in the /System/Library/Extensions folder apply permissions as follows (easiest way is using the utility BatChmod) before rebooting: owner root RWX, group wheel R-X, everyone R-X.

Leopard tweaks:
Designable.nib removal
After installing Leopard and all applicable updates, run the following in Terminal to save disk space by removing the designable.nib debug files that Apple seemingly mistakenly left in Leopard (they were not in previous or subsequent versions) - I have always done this with no problems, but this is at your own risk if it breaks anything, read more at https://appleinsider.com/articles/08/06/27/solving_the_mystery_of_snow_leopards_shrinking_apps

Monolingual 1.4.5 can shed several hundred megabytes by removing unneeded language localization and multi-architecture features.
Additional Leopard speed and performance improvements are covered on this post.
