I obviously missed another update: 15.7.8. But still working with Sequoia 15.7.9 as expected.

Did I miss Sequoia 15.7.6? Or did Apple skip it?

Anyway – Fireface 800 and Sequoia 15.7.7: Thumbs up some more!

The mixer window opens on start up as a log in item. The feedback comes from the M4 computer through the fireface 400

After disconnect and reconnect the unit works fine!

Any advice gratefully received

Many thanks

The last version of Sequoia is causing digital feedback through the soundcard (fireface 400) on start up. When reconnected works fine.

Anyone got an idea how to avoid this start up glitch?

Many thanks

There will be. Probably for several years. They usually are no big things though. Just security updates mostly.

I'm sorry I had no idea there are still updates coming out for old MacOS.

This thread is about Sequoia. What was released on or around the 11th Nov was the Sequoia update 15.7.2 I already mentioned above. As expected the Fireface 800 works with this and also the FF 400 should. They should still work with all upcoming Sequoia updates as I can't imagine Apple suddenly dropping Firewire support within the last rounds of Sequoia.

Do the drivers still work with this upgrade?
Many thanks

I did not see any release at 11.11.2025
We are at 26.1 Tahoe at the moment and Firewire no longer works as explained in the RME webpage :

Just for the sake of completeness: Sequoia 15.7.2 also still works as expected.

Same with Sequoia 15.7.1.
