 1 | AzulPatcher4600
 2 | ===================
 3 | 
 4 | # Superseded by [WhateverGreen](https://github.com/acidanthera/WhateverGreen) ([info](https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.OldPlugins.en.md))
 5 | 
 6 | Lilu plugin for haswell hd4600 mobile igpus  
 7 | 
 8 | This seems to be noticeably faster than clover kext patching even when injected with Clover.
 9 | 
10 | ### OS Compatibility:
11 | Yosemite to High Sierra
12 | 
13 | #### Requirements:
14 | - Lilu 1.2.x
15 | 
16 | #### Tested on:
17 | - Lenovo Y50-70 FHD
18 | - Lenovo Thinkpad T440p
19 | - hasee Z7M-i78172D1 (and other laptops based on the Clevo CP65S / Sager NP8650 / P650SA)
20 | 
21 | #### Features
22 | - Patches HDMI audio
23 | - Applies the 9MB cursor patch with 2 ports only
24 | - Disables the unused 0204 port (Fixes graphic lockups on some laptops)
25 | 
26 | #### Credits
27 | - [Apple](https://www.apple.com) for macOS  
28 | - [vit9696](https://github.com/vit9696) for [Lilu.kext](https://github.com/vit9696/Lilu)
29 | - [RehabMan](https://github.com/RehabMan) for the patch
