Hello everyone!

I need help with installing macOS on my laptop. I have been trying for 3 days with AI assistance but keep getting different errors every time. I'm not sure if macOS can even be installed on this laptop at all.

My Laptop:
  • Model: ASUS ZenBook UX462DA (box says UM462D but Windows shows UX462DA)
  • CPU: AMD Ryzen 5 3500U with Radeon Vega Mobile Gfx
  • RAM: 8GB DDR4
  • SSD: 256GB NVMe
  • WiFi: Intel AX series
  • Touchscreen: Yes (10 touch points)

My questions:
1. Is it even possible to install macOS on this laptop?
2. Which version of macOS works best for this hardware?
3. Does anyone have a working EFI for ASUS UX462DA or similar Ryzen 5 3500U laptop?

What I tried:
  • OpenCore 1.0.7 with macOS Monterey 12.7.6
  • SMBIOS: iMac19,1
  • Always getting error: usr\standalone\OS.dmg.root_hash not found
  • The firmware keeps reporting different Board-IDs each boot (Mac-AA95B1DDAB278B95, Mac-63001698E7A34814)
  • Tried CleanNvram, ForceSecureBootScheme, different recovery files - nothing works

I am a beginner and would really appreciate any guidance or a working EFI to start from.

Thank you so much!
 
  1. Yes it is possible, but people have had mix results when running macOS on an AMD laptop.
  2. Any version from High Sierra up to and including Tahoe, should be possible with the correct EFI.
  3. No.
Your AMD laptop should be using a MacBookPro16,2 SMBIOS, not an iMac19,1 (desktop) SMBIOS.

Zip and post a copy of your OpenCore EFI and let us see what you are using, as without that we won't be able to suggest anything helpful.

Thank you so much for your reply!

I have a few follow-up questions:

1. About USB Ethernet adapter:
Is it absolutely required during installation? Is there any way to install macOS without a USB Ethernet adapter?

2. About AMD Vega VRAM (512MB/1GB):
I checked my BIOS but I cannot find any option to increase VRAM for AMD Vega graphics. My laptop is ASUS UX462DA and the BIOS is very limited. Is there any alternative way to set this through OpenCore or a kext?

3. About my EFI situation:
I have been trying for 3 days and have made many different EFI configurations - I got confused and lost track of which one is correct. I am attaching my current EFI which I believe is the latest and most correct version.

Could you please help me build a proper EFI from scratch with a step-by-step tutorial? I am a beginner and really want to get this working.

My specs again:
  • Laptop: ASUS ZenBook UX462DA (box says UM462D)
  • CPU: AMD Ryzen 5 3500U
  • GPU: AMD Radeon Vega 8 (iGPU)
  • RAM: 8GB DDR4
  • WiFi: Intel AX series
  • Bootloader: OpenCore 1.0.7

Thank you for your patience!

I am recommending that you use a USB to Ethernet adapter because your laptop doesn’t contain a Ethernet port. If you are using the macOS Recovery method to install Monterey you will have to download the full macOS installer (12+GB) as part of the installation. But your Intel WiFi card won’t work during the installation process. As the kexts required for the WiFi won’t be injected during the macOS install process.

The only way to get around not downloading the full installer as part of the install is to create an offline installer, which already contains all the necessary files (12+GB) for macOS.

The step-by-step tutorial is already available, i.e. the Dortania Ryzen guide. There are common features that both an Intel an AMD system require, which you need to read about and include when creating your OpenCore EFI and installation media.


There isn’t a specific guide for an AMD laptop, as it is not a commonly used computer for running macOS. Due to the limitations of the components used in these laptops.

If you can’t find a specific bios setting to increase the amount of RAM available to the AMD Vega IGPU, then it may not be worth installing macOS on that system. As a limitation to the IGPU, where it only has say 256mb available will prevent the GPU running with full graphics acceleration, and that is something that is essential for any system running macOS.

There may be a third-party tool that allows you to access some hidden features in the AMD Bios, I.e. ‘Smokeless_UMAF’, which may allow you to increase the amount of RAM allocated to the IGPU. But be very careful with this Bios Tool, don’t go changing things if you don’t know what they do. You could easily brick the system by changing the wrong Bios entry.

I will have a look at your EFI folder when I am next at my desk, which should be later today.
 
Try this revised EFI folder, see if it gets you any further towards installing macOS Monterey.

Post a photo of the Verbose text on the laptop's display, if the system kernel panics.
