This project targets at giving the relatively complete functional OS X for both Dell Precision M3800 and XPS15 9530. Before you start, there's a brief introduction of how to finish powering up OS X on your laptop:

1. Create a vanilla installation disk(removable disk).
2. Install Clover with UEFI only and UEFI64Drivers to the installation disk just created.
3. Replace the origin Clover folder with the one under my Git/M3800/CLOVER.
4. Patch bios to unlock bios menu.
5. BIOS settings:

- Advanced:
    CPU Configuration/CFG Lock = Disabled
    CPU Configuration/LakeTiny Feature = Enabled

    SATA Operation = AHCI 

- Chipset:
    PCH-IO Configuration/XHCI Mode = Smart Auto

    System Agent (SA) Configuration/Graphics Configuration:
        Aperture Size = 512MB
        DVMT Pre-Allocated = 160MB
        DVMT Total Gfx Mem = MAX
NOTE: Once you modify your settings in BIOS(especially Graphics Configuration in SA), you have to remove previous ACPI tables first, redump ACPI tables by press Fn+F4/F4 under Clover, and run deploy.sh again to patch your ACPI tables again.

6. Install OS X.
7. Once you finish installation of OS X, you can do the following steps to finish the post installation of OS X.

Download the latest version installation package/directory by entering the following command in a terminal window:

git clone https://github.com/syscl/M3800

This will download the whole installation directory to your current directory(./) and the next step is to change the permissions of the file (add +x) so that it can be run.

chmod +x ./M3800/deploy.sh

Run the script in a terminal windows by(Note: You should dump the ACPI tables by pressing F4/Fn+F4 under Clover first and then execute the following command lines):

cd M3800
./deploy.sh

Reboot your OS X to see the change. If you have any problem about the script, try to run deploy in DEBUG mode by

./deploy.sh -d

Note: For two finger scrolling you need to change the speed of the Scrolling once to get it work and also have to enable them in Trackpad preferences.

• Huge style change! We don't have to reboot 2x due to the change of ig-platform-id! Once you update your OS X(do not reboot), and run the deploy.sh again, then, you can enjoy every functions of OS X you want.

• Another problem is that after a full sleep, I can't reproduce the fix I made to fix the HP lose sound problem after a cold boot, really boring since I usually plug in HP all the time. I'm finding new way to fix this annoying problem. (After extensive explore, I believe this bug is produced by AppleHDA, since there's no such problem under Windows and Linux. Actually, Linux has this bug, but it can be fixed through a re-plugged-in HP.)
