This doesn't appear to be an issue with the kernel based driver. Is there any negatives to me rolling over to the kernel drivers? I mean is the performance better or negligible?

Thanks

The readme text in the driver tells,
Installing the driverkit driver will remove the previous driver also kernel kext.
So you just have to install the new driver and reboot.
And read the readme text file.

OK thanks a lot NP I'll read;)!

You could try to use driver 3.33 and use the Safety Offset setting Large.

Hi, thanks for this - I did that. Inadvertently I installed the Kernel driver! (I realised too late, but booted into the Startup Security Utility.

It works fine there, even with a short safety buffer.
If I decided to try the driver kit version again, how would I remove the Kernel one? I seemed to struggle with this previously. It's most likely me and lack of knowledge so apologies for that.

I take it that the Kernel driver is essentially more efficient, despite improvements by Apple on the driverkit side.

Thanks for you help.

Does this also affect other audio software or streaming services?

Hi, not Logic or other DAWs. I think it's probably a small buffer on Apple's own apps. Thanks

When I'm not doing audio work I often use my RME UFX to listen to other stuff. Recently I was editing some graphics in Pixelmator Pro. As I added some graphical effects (eg: gaussian blur which I believe use the Mac M1 GPU) the audio stutters. This happens if I'm listening to audio with Apple Music.

I tested the internal audio of my Mac Studio via headphones and also with a USB-C to spdif I have lying around. Both of these play back fine.

I contacted Pixelmator but as it's specific to the RME interface they couldn't offer any solutions.
I'm running:
OSX Sonoma 14.6.1
Mac Studio M1 32gb, 1tb, 32 gpu cores.
RME Fireface UFX
Driverkit driver
Firmware: 361
Driver 4.14

If anyone knows if this can be resolved I'd be grateful. I'd prefer not to install the kernel driver but maybe that's what's required.
Thank you!
