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This repo is no longer maintained, since I have switched from XPS to a real MacBook Pro.

This repository contains my own files on the installation and configuration of macOS Catalina (10.15.1) on the Dell XPS 15 (9550)

• 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.

Structure

• CLOVER: Clover EFI folder.
• Kexts: Kexts which should be installed in S/L/E or L/E.

My laptop

Dell XPS 9550

• i5-6300HQ/HM170
• Nvidia GTX960M / HD530
• 3840x2160 (QHD)
• DDR4 2133 16G (8G x 2)
• Dell Wireless 1830 (BCM43602 + BCM20703A1)
• 512GB NVMe SSD (Samsung SM951)
• BIOS Firmware 1.9.0

Status

Working

• 98% of the system

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)

Tips

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

1. Open /System/Library/Extensions/AppleGraphicsControl.kext/Contents/PlugIns/AppleGraphicsDevicePolicy.kext/Contents/Info.plist.

2. Find the Borad-ID which used in your config.plist such as "Mac-B809C3757DA9BB8D" or "Mac-65CE76090165799A" or "Mac-DB15BD556843C820".

3. Replace the attribute Config2 with none

4. Execute commands sudo kextcache -system-prelinked-kernel and sudo kextcache -system-caches.

5. Reboot and everything is done.
