[SUCCESS] Gigabyte Designare Z390 (Thunderbolt 3) + i7-9700K + AMD RX 580

Hey @CaseySJ , did you chance upon a thread in another forum on OsxAptioFix2Drv-free2000. It's started by a guy called u/apianti. He's the developer for OsxAptioFix2Drv-free2000 and strongly recommends against using it. Somehow had success with AptioMemoryFix-64.efi but for me I get a panic on reboot.

I have this exact build with a Saffire RX580 and I've been having issues with Pro Audio Apps such as Ableton Live & Logic where I'm getting occasional audio glitches and drop outs when working in a project. The issue never occurred on this system when using Windows 10 with the same hardware. I've tried multiple USB Audio interfaces and I'm getting the same issue with both. (Scarlett 2i2 & Apogee Duet 2). If I run the audio to my monitor via the RX580 Display port output, it works fine. When listening to audio such as youtube or audio files, it works fine also. Any idea what it might be?

I'm running SMBIOS 19,1

I wouldn’t say there’s a best memory kit because there are so many excellent choices. Because this is an Intel platform, we generally see the widest compatibility. AMD systems may be just a little more picky.

When choosing memory, l look for:

• XMP 2.0 compatibility.
• Memory speed. Anything over 3200MHz is generally unnecessary for content creation. Higher speed memory may have some benefits in intense gaming at high frame rates.
• Choose a reputable manufacturer. Avoid no-name brands and unknown brands. Make sure it comes with Lifetime Warranty.
• Also choose DIMMs with preinstalled heat sinks.
• Choose Unbuffered DIMMs (UDIMMs). By default they are unbuffered. Buffered or ECC memory will clearly indicate that.

Having said this, memory capacities up to 64GB are no problem, but we’ve seen some one report of problems with 128GB in just the last couple of days.

Came here to ask the same thing. I saw that post. Seems like some users there are able to successfully use AptioMemoryFix-64.efi.

The part about how the driver erases memory without checking is worrisome. I don't know the validity of the claims however.

I managed to get it to work without the OsxAptioFix2Drv-free2000. No crashes so far. The system definition had to be changed to iMacPro1,1 from 19.1 for me. I got it to work with the internal graphics and with RX590. Copy of my EFI is here without the serial/board numbers.
The ZIP has 2 folders.
Use this [EFI 20th July with new EFI updated - 4 and RX] with the RX and this [EFI 20th July with new EFI without RX - 5] without the RX - this has the Framebuffer patch applied.

Do you have any other PCI-e cards installed besides the RX590?

 

[mango1122]

I have the Wifi/Bluetooth PCI-e with Padarsey BCM94360CS2 in there. The RX590 is in slot 2. In addition there are 2 HDD and 2SSD (1 MACOS and 1 Win)

Thanks. I've always been able to use AptioMemoryFix.efi with only my Vega installed. However, installing any other PCI-e card like my Fenvi T919 required the use of OsxAptioFix2Drv-free2000.efi. I'll give it another whirl with AptioMemoryFix.efi and multiple PCI-e cards and report back.

EDIT 7/22/19 - I've reverted back to OsxAptioFix2Drv-free2000.efi, along with EmuVariableUefi.efi and RC scripts. While I'm able to boot with AptioMemoryFix.efi only, I don't get native NVRAM and KPs on reboot/shutdown. I was finally able to install EmuVariableUefi.efi along with RC scripts to emulate NVRAM, but it's so hit and miss; like once out of every 20 tries on boot I don't get an allocation error and am able to boot into macOS. I tried using various slide values per the dev's instructions, but it wasn't consistent either. Based on my board's memmap, it was either slide=0 or slide=229.

• Internal Graphics => Disabled

I just do not use this setting:

Because when disabled, it generates a problem in PREViEW on the Mac with photos and PDF, they simply lock and do not open.
You have already tried using the preview to see if it works correctly with this option disabled. ?
