Hey @Maax, I believe I ran into the same problem as you. Nearly-new Mac Studio, running Sequoia. Iāve moved from Window due to the reliability of Macs - and they ājust workā, right? Tried getting my UR824 working has been anything but.
I used the driver from this forum but first time round I accidentally clicked āOkā instead of the button to open settings. After that, it never showed up, and the permission was never listed in the āPrivacy & Securityā settings.
I managed to solve this by fully uninstalling the driver, installing the previous beta, and then uninstalling that and reinstalling the new one. But, this is unnecessary, as I found out how to check/set the permissions - they are NOT where the documentation says.
Go to Apple Settings ā General ā Login Items & Extensions ā (scroll to bottom) Driver Extensions ā Click āiā ā Toggle the Yamaha Steinberg USB Control Panel.app
This ONLY shows up the first time and NEVER again, so if you miss it, you will spend ages fruitlessly hunting and being show the WRONG area of the settings! Ever so frustrating.
After this, running the Yamaha Steinberg USB Control Panel from Applications should display an āOkā button - previously it would show āActivateā. Also, the UR824 should show up in Audio MIDI Setup ā Devices, and changing the bitrate should change the corresponding light on the front. Thatās a quick and easy way to verify some driver communication.
BUT! This does not have a happy ending - yet. Although I managed to get sound out of my UR824, it keeps cutting out. It will play anything from 1-20secs of audio and then cut out for 1-5secs. Itās unusable.
In Steinberg/Yamahaās defence, I have exactly the same problem with a Native Instruments Komplete Audio 6 - it shows up as a device, but then keeps cutting out. From this sample set of two, I conclude that there may be an issue with Sequoia. Unfortunately, I donāt have Sonoma available to test on, as I upgraded a month ago and before I started hooking up any of my audio kit. Still, that may or may not be useful information.
I guess we wait for a fixā¦ but I am quite surprised at the hoops we have to jump through, using a beta driver, no full native support for Apple Silicon (just the driver, it seems?), and the time taken after each release (you Steinberg guys do know you can test MacOS betas before the full release, right? Iām looking at you, @Ed_Doll). Quite honestly itās a travesty, and I nearly gave up and bought a Focusrite Scarlett (it seems those guys do have good Mac support, but I canāt vouch personally).
All in all this means Iāve wasted 2-3 hours on this and still canāt use it. Sighā¦
Anyway, I hope this helps you, and it will be interesting to hear if you also have the audio cut-outs
