Heya - I've got a problem with a thunderbolt port - it is detecting USB-C drive but is not detecting TB3 device (like Blackmagic)
Everything is enabled in the bios (dual boot and windows works perfectly fine) - I can rule out cable or TB device problem.
TB section says Thunderbolt/USB4: No drivers are loaded.
Do you have any solution?

Hi @Lovely-XPP, thanks a lot for your great work in getting everything running for Dell 7480 laptop. I had a working EFI, but yours is just better. Only one shortcoming I notice is that when connected to a 4K monitor via thunderbolt port, the hackintosh recognises only 2560x1600 resolution instead of full 3840x2160.
I am trying various guides available online, but couldn't get it working so far. If you know how to solve this issue, please do share with me.

Thanks once again!

I heard that you have some headphone jack microphone problem. I not sure that method that I give will work on your device but it work on my latitude 7480

1. Try Combo Jack This Method work on my device.
2. if first method not work try SSDT I attach below (It from latitude 7480 clover) and install codec commander

Let me know that this method work on your device or not
Oh this is my latitude 7480 spec

• Dell Latitude E7480
• Intel core i5-7200u
• Intel HD Graphics 620
• 16gb of ram
• SandDisk X400 M.2 2280 512GB (From Factory)
• Intel Wireless AC 8265

SSDT-ALC256.zip

Similar to the issue #11, I am not able to run my 4K monitor at optimal resolution of 4K. The resolution is capped at 2560x1600 only. @Lovely-XPP have you tested your config on a 4K monitor.
Thanks a lot for your great work and for sharing your resources with us!

Stuck with me on the Apple logo while loading progress...

Hi there,
The installer USB that I build (Ventura 13.4) loads for a while and then suddenly reboots. I’m attaching a screenshot of where it gets to in verbose mode, note some HID device crashes?

I’m using the Intel wireless config.plist that you supplied.
My configuration is basically similar to yours but I have i7 7600U and 16 GB RAM. Notably I have the same graphics (620) and high DPI screen.
One thing is that I am using your USB map instead of making my own maybe that could be causing the behaviour but I doubt it… I have to get in to MacOS to make my own USB map!
The BIOS is set up as you described.

Thanks for any insight you can provide!

Hi Everyone,
I have been trying to install macOS Ventura on my Dell Latitude 7480 (non-touch) Laptop for some days now and I haven't been able to do so. I have tried almost everything.
I have done all the required changes listed in this code in the bios.
Whenever I try to boot into macOS recovery it runs code for some time and then the laptop restarts. I have also tried flashing Ventura dmg file onto the USB using "etcher balena" and then copying efi file in it but it also didn't work. The apple logo shows up, the line loads up to 30% and then the laptop restarts.
I read online that you have to use USB 2.0 port to install it. Since there is no USB 2.0 port on my laptop, I was installing it using USB 3.0 port so maybe that is the issue. I read that you have to map the USB port and place some "USBMap.kext" file in the kext folder. Since there was file with such name attached to this code. I thought that it may work but it didn't.
My Laptop Specs:
Dell Latitude 7480 (non-touch) with fingerprint scanner
Core i7-7600u (Kaby Lake)
8gb ram
Intel HD Graphics 620
FHD Screen (1920 x 1080)

Awaiting your assistance.
Your help will be highly appreciated.
Thanks in advance.

so I have a Dell Latitude 7480 and my old EFI the mouse doesn't work how did you fix it because I need to know if you can tell me that will help me alot

Followed dortania guide to create USB Stick with Mac OS Ventura.
Applied EFI folder (from this repository - version 9.00) and while loading the process hangs to: "SMCLightSensor alsd: @ No Iterator"

Here is my system detail:
Latitude 7480 i5-7300U
1920 x 1080 no touchscreen
256 SSD SKhynix
BCM94360NG (Wi-Fi / BT4) card (that should works OOB)

Hello,

Firstly, congratulation for great job to creating this EFI !!!

I use the EFI on Dell E7480 with non touch display 1080p (Ventura 13.0.1).
I had a problem installing Ventura with this EFI (look at screen below) but I fix it by set ReleaseUsbOwnership=true in config.plist.

Now, I have problem with sleep. After sleep and press power button or Fn+Insert I have black screen.
In hackintool internal display is visible as Unknown Display. In IORegistryControler I have only AppleBacklightDisplay (not AppleDisplay).
I Have original dell dock station with USB-C cable and the problem with sleep is absent with dock station and external monitor.

I Try set EDID, modify the PciRoot(0x0)/Pci(0x2,0x0) but without success.
I've used the latest release EFI (OC 0.8.6 with correct AlpsHID which repair trackpad :-) ).
Have you got any idea what I can do to repair the sleep?

Best regards

Hi,
This repo is awesome, thank you for making it. I'm trying to use external microphone and plug it in jack but it's not detected. Have you try external microphone or headphone microphone? I'm so confused because I can't use mic for my webinar.

Thank you.

Thank you for maintaining this.

I have a similar laptop E7470 model. I read your SSDT files and you have patches for Fn keys, Sleep and LID. Both the laptops have the same keyoard layouts. I tried using your SSDTs but when activating Fn+Insert hotkey, it goes to sleep but when I wake up, it takes so much time with blackscreen and the Brightness keys stop working. I need to reboot to fix it.

Are you facing similar issues ?

I tried installing Monterey with your EFI but it's restarting before the login screen.

My configuration is Latitude E7480, i7-7600u, Full HD display, intel HD 620.

Please guide me..

Do I just use the latest release or do I combine latest release with previous release? Also latest release seem to have debug info when booting and shutting down.

Applealc kernel panic e system reboot….. have you some idea? Thank you

With the AlpsHID.kext v1.3 the trackpad is not working properly on my E7480.
I went over to https://github.com/blankmac/AlpsHID and downloaded AlpsHID.kext v1.2.
I replaced the original in the EFI folder with v1.2 and now the trackpad is working properly.
Ik only replaced AlpsHID.kext but not VoodooI2CHID.kext. Also I did not change anything in config.plist.

i can't update to macos ventura official using this EFI

usb install crash after 30 second and pc restart. I tried "If crashed in installing macOS from USB, try Enable UEFI->Quirks->ReleaseUsbOwnership, thanks @krzysinek (#22)" but i have no result. have you same idea? thank you and sorry for my english

Hi.. Thanks for updated guide for E7480.. I have tried to boot BigSur 11.6.2 with your EFI.. I have same config as yours.. But Full HD display.. I'm getting errors..

Greetings I have a small problem with the trackpad.

The drawback is that every time I'm going to use it, it's as if I'm using both fingers at the same time instead of just one.

I thought my trackpad was defective but on windows it works perfectly.

Could you tell me why this happens?

I am using MacOss Monterrey in version 12.5.1 with opencore 8.3

after loading verbose, my screen goes black, but the external monitor is still on and my mouse is on it
Could you help me to fix it?
