macOS Catalina (10.15.1) on the Dell XPS 15 (9550)

This repo is no longer maintained, since I have switched from XPS to a real MacBook Pro.

Thanks darkhandz for his High Sierrra guide and wmchris for his guide. Please read these two guides before you use my files.
Use MacBookPro13,3 SMBIOS, much thanks for @syscl.
- Note that you need to modify AppleGraphicsDevicePolicy.kext to make external monitors work.
- The model identifier is also correct now.
- I hide my serial number as C02*****GTFN, you may generate it by your own.
Caps and Left-Ctrl is exchanged in VoodoooPS2, you can modify it if you don't like this keyboard layout.
OsxAptioFix2Drv-free2000.efi is used to fix the slide parameter in booting, you may try OsxAptioFix2Drv-64.efi or OsxAptioFix3Drv-64.efi instead for your laptop.

Dell XPS 9550

Working

Not working

TB3/type-C port hot-plug maybe work.
- I find that my TB3-DP adapter can hot-plug and the 4K external monitor works fine. Need more test.
- My Nexus 6P is broken so I can't test.
SD card reader (waiting for good news from this post)

To make external monitor works (if you use iMac17,1 SMBIOS), you should do following steps:

Open /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/Info.plist.
Find the Borad-ID which used in your config.plist such as "Mac-B809C3757DA9BB8D" or "Mac-65CE76090165799A" or "Mac-DB15BD556843C820".
Replace the attribute Config2 with none
Execute commands sudo kextcache -system-prelinked-kernel and sudo kextcache -system-caches.
Reboot and everything is done.
