macOS Catalina on Dell Inspiron 7373
This repository contains an OpenCore configuration to run macOS Catalina (10.15.4) on Dell Inspiron 7373 2-in-1 laptop with OpenCore 0.5.7.
System Configuration
- CPU: Intel Core i7-8550U
- RAM: 16GB 2400MHz
- SSD: SK Hynix SC311 256GB SATA3 M.2 (running latest firmware)
- 1080p Touchscreen display, supports stylus (ELAN2097)
- I2C Precision touchpad (DELL07EB)
- Intel 7265 Wi-Fi card
- Realtek ALC295
- Realtek USB Camera + IR Camera (for Windows Hello)
- Firmware: 1.16.0
What doesn't work or works partially
- Combo jack (according to @baddles, you have to pull the headphone jack away from the computer for about 0.2mm, then change the slider balance values for it to work properly)
Solution: VerbStub (included) + ComboJackFix (disable SIP before installing)
- Wi-fi card - works partially with itlwm (not provided in the repository - if you want to try it, compile it by yourself or wait for the official release builds). For the best results, it is recommended to replace the card wih a macOS compatible one (look here for some recommendations).
- IR Camera
- In some rare cases, the VoodooI2C will crash on boot and thus the touchpad won't work. A simple restart will fix that - I do not currently have a better solution.
Any contributions are welcome - I'm by no means a Hackintosh expert (still learning a lot of things), so there are probably a lot of things to improve. Also, check out the Issues tab.
BIOS Configuration
Turn off the Secure Boot. That should be all.
UEFI Variables
In order to run macOS without having to use WhatEverGreen's framebuffer patching and CFG-related booter quirks, it is strongly recommended to modify a few UEFI variables. To do that, you can use the included ModifiedGrub.efi (credits brainsucker), which provides the setup_var command.
| The following variables should be updated:
Variable |
Offset |
Default value |
Desired value |
Comment |
| CFG Lock |
0x4C7 |
0x01 (enabled) |
0x00 (disabled) |
Disable CFG Lock to prevent MSR 0x02 errors on boot |
| DVMT Pre-allocated |
0x76D |
0x01 (32M) |
0x02 (64M) |
Increase DVMT pre-allocated size to 64M |
| DVMT Total GFX Memory |
0x76E |
0x02 (256M) |
0x03 (MAX) |
Increase total GFX memory limit to maximum |
DISCLAIMER: those offset values are taken from 1.15.0 and 1.16.0 firmwares. DO NOT use them with older versions unless you have checked that they are the same.
Usage:
setup_var <offset> <value>
ex.
setup_var 0x4C7 0x00
Notes
- The included CpuFriendDataProvider is made for i7-8550U. If you have the i5-8250U processor, DO NOT use this kext. You can make a new data provider kext for that CPU (and make a PR!).
- In "Optional" directory, you can find "NullEthernet.kext" and "SSDT-RMNP.aml" files. If you haven't swapped the included Wi-Fi card, you may need to use them for Apple services to work properly.
- In the same directory, you can find two kexts - IntelBluetoothFirmware and IntelBluetoothInjector. Add them if you want to use the included Bluetooth card.
- For HiDPI scaling options, I recommend to use one-key-hidpi.
