• Thanks. I had seen other release notes but none that had that much detail. The comment down near the bottom about "AMD, AMDRadeon and Intel kernel extensions increase in build numbers" might point me in the right direction. That may indicate that updated AMD kext's did fix the issue but I haven't heard that yet.

If you want to ask about specific problems with your eGPU, then please state them. You are not using an Apple product, so you should direct your questions to the manufacturer. Razer does not make Apple compatible hardware, and may not be aware there are problems.

Nope, no specific problems with my eGPU at the moment. I would have stated so if I did have some. I'm trying to prevent them from occurring by not installing Catalina until those problems posted on the web have been fixed.

Some examples:

And, actually, Razer does make Mac compatible products. Regarding my eGPU chassis, the Core X, this is what Razer says:

"Does the Razer Core X work with a Mac?

Yes, they are compatible with Thunderbolt 3 Macs running macOS High Sierra 10.13.4 or later and requires a compatible AMD graphics card."

However, you are correct that they may not 'know' that problems have cropped up since Catalina.

And, from Apples support article https://support.apple.com/en-us/HT208544

"AMD Radeon RX 470, RX 480, RX 570, RX 580, and Radeon Pro WX 7100

These graphics cards are based on the AMD Polaris architecture. Recommended graphics cards include the Sapphire Pulse series and the AMD WX series.

Recommended Thunderbolt 3 chassis for these graphics cards:

• OWC Mercury Helios FX
• PowerColor Devil Box
• Sapphire Gear Box
• Sonnet eGFX Breakaway Box 350W
• Sonnet eGFX Breakaway Box 550W
• Sonnet eGFX Breakaway Box 650W
• Razer Core X
• PowerColor Game Station
• HP Omen
• Akitio Node"

So, per Apple the RX 580 combined with the Razer Core X should be compatible with the Mac. And it has been up to the release of Catalina.

I could have been more clear in my question. Instead of "I was wondering if the latest update to Catalina (10.15.2) fixes these issues." I should have asked: "Did the 10.15.2 update fix the problem with some Macs not being able to boot when connected to an eGPU using an RX580 and running Catalina." I assumed anyone that either was having this problem or had read about it would understand what I was talking about. My bad. I hope this post provides you sufficient information so that you don't have to be clairvoyant.

Yep, 100% aware of this. I wanted to crowd source the answer. Figured that there are a lot more 'users' than 'Apple Support' out there that might either have experienced this problem or run across an article where someone said it was fixed. Especially since I have not seen an 'official' admission from Apple that the problem exists. There may be one, but I have not run across it.
