Readme

NexPostFacto 64-Bit ATI 10.9 Beta
---------------------------------
A nearly bugless alternative to MacPostFactor, remade from scratch with careful testing and a "less is more" patching philosophy.

Supported Macs
--------------
iMac4,1 (if CPU upgraded to Core 2 Duo)
iMac5,1
MacBookPro2,1 2,2
Xserve1,1 2,1
MacPro1,1 2,1 (with X1900 XT)

Instructions
------------
Format an 8GB+ USB, or hard drive partition, as Mac OS Extended (Journaled)
Extract the zip and cd to the directory
Run: ./oipatch.sh /path/to/Install\ OS\ X\ Mavericks.app /Volumes/USBOrPartitionNameHere
You MUST select Y to erase the partition or the script will not work!

Boot from the USB or partition, install OS normally.

AFTER all OS AND security updates, install the mavlegacygfx.pkg that was copied onto the installer drive. If you accidentally install it before doing updates, the Finder will not open!

Notes compared to normal 10.9
-----------------------------
Photo Booth lags
Find my Mac and FileVault do not work because they require a recovery partition
Spotify has graphical glitches making it unusable if hardware acceleration is enabled (disable it in the menu)
When you minimize some windows which use hardware acceleration such as web browsers, horizontal yellow lines will appear during the minimize animation
Overlays of hardware accelerated video (like YouTube controls) flicker rapidly

Later
-----
investigate window minimize bug
fix disk utility repair permissions errors
actual blur from 10.9dp3 cg instead of disable?

Thanks
------
MacPostFactor for the idea (but none of the code)
random_user_online for inventing the name
tiamo for boot.efi
All the testers (see the About app for credits)
