I have a Sonnet Solo10G SFP+ card that use to work just fine, till I updated to the latest Jan 2020 driver on Windows. This card officially supports Catalina OTB.
According to this thread updating to certain drivers on Windows turns off a few flags that makes the card lose functionality on macOS.
The card refuses to work on macOS. It is now Identifying as a 107S, instead of 100S (despite the PID/VID being the correct one) and while the ethernet shows up in system information, it will always show as disconnected.
I tried everything including:
- Upgraded to latest firmware from Sonnet (Marvell site)
- Reverting to older driver on Windows
- downgrading/upgrading IONetworkingFamily.kext tried latest beta
- Deleted all the preferences files
- Switched from Clover to OC (after tweaking OC, I can feel things working a lot better)
- Fresh install
- tried a different identical card (I have two)
- I even reverted back to an older disk image.
- Changed slots
- Upgraded to beta BIOS
Is there anyway I can get it to work again? It uses Aquantia AQC100S.
To be clear it works perfectly well on Windows and Linux.
Here are my specs (not sure if its relevant):
- 9900k
- Gigabyte z390 Wifi pro
- Radeon RX 5700 XT 8 GB
- Titan Ridge Thunderbolt
- Fenvi T919 Wifi/BT
