Preparation Phase

Dell Inspiron 5370 has a i5-8250U, UHD 620, 256 GB M.2 and a QCA9377 (which I've replaced later with a DW1830 bought on AliExpress)

I've made a dual boot with Arch Linux (150GB of / for Linux in EXT4, and 100 GB for Mac).

I don't have a Mac so I've used a VM to download the Mojave image, prepare the USB thumb drive and the EFI folder.

After I prepared the USB drive and did a little digging for the EFI folder suited for the install, I've configured and added a new Boot Entry in the BIOS (because the USB drive wasn't detected in the boot menu) and installed the OS

BIOS Settings

^{N.B. Because Mac OS Installer didn't detected the Free Space onto my SSD, I've formatted it in EXFAT in order to be recognized during the installation phase}

Post Install Phase

After installing Mac OS and setting it up, I've created a new EFI which granted me the QE/CI (graphics acceleration) and the brightness control using the FN+F11 and FN+F12 keys

I've followed the WhateverGreen Framebuffer patching method and I got 1536MB.

^{N.B. Some people use the "framebuffer-unifiedmem" property (Devices=>Properties} which grants 2048MB of VRAM. This patch is not recommended)

For the brightness control on Dell laptops I've renamed in the ACPI=>DSDT=>Patches section of the config.plist the following methods:

Rename _DSM to XDSM
Rename OSID to XSID (to avoid match against _OSI XOSI patch)
Rename _OSI to XOSI
Rename BRT6 to BRTX, use with SSDT-BRT6.aml, SSDT-PNLF.aml, AppleBacklightInjector.kext, and VoodooPS2Controller.kext to fix brightness keys

and added those SSDTs in ACPI/patched:
