Topic: macOS 10.15 (Catalina) Drivers available for testing

Mac OS 10.15 (Catalina) driver preview

RME has compiled drivers for use with the next Mac OS operating system 10.15 (Catalina), and offers these for interested users and everyone testing Catalina as preview download.

These drivers might not work as expected with older OS – the usual beta warnings apply (only use them on test systems etc).

Background: On fresh installations of 10.15 new driver packs are needed that are fully notarized. The drivers are mostly identical, but these new packages also include an updated TotalMix FX 1.62 beta 4, which is compiled with the latest XCode.


- The old 'remove USB device hangs USB' issue is still present under 10.15 betas

- Update: issue resolved in latatest 10.15 beta (The CPU load of the WindowServer is higher than usual with TotalMix FX).

- The USB 3 MIDI plugin of the USB driver is updated as the former one didn't work under 10.15 beta

Be careful during installation! The Privacy dialog to allow the driver loading can be hidden behind the driver's final reboot dialog as they come up nearly simultaneously – do not reboot before allowing 'RME GmbH' to load!

TotalMix FX 1.62b4 fixes two pan issues for UFX+ and UFX II which were reported on this forum. It also adds an ARC USB option 'Push-off or-on', see

Re: macOS 10.15 (Catalina) Drivers available for testing

I will never ever buy another audio device than from RME. Name me another company that supports 15 year old devices? (I've gots 2 FF400s still going strong with latest Macs). The service is so good I'd like to pay for it. Suggestion: add a "Send me beer"- button to your site to satisfy this need in these long upgrade cycles. smile I love the fact it also saves the environment. I don't need to buy some crap every other year.

Re: macOS 10.15 (Catalina) Drivers available for testing

Fully agree. Thats what I always tell people who have not the experience and overview over the recording interface market.

In contrast to that: see i.e. Windows related products: no win7 support anymore for modern CPUs and mainboards :-((
Microsoft is heavily fighting that we shall love Win10 and forget about the better 7 ;-)
