I’m running Mac OS X 11.6 on a MacBook Pro Retina, 13-inch, Mid 2014 with an Intel i5 processor.
I have installed the Yamaha Steinberg USB Driver 3.05 and UR Tools for UR V2.2.2
The USB driver does not show up in the Audio MIDI Setup panel.
dspMixFX_UR44 recognises the connected UR44.
Researching this problem suggests that the USB driver has failed to install. Though all the articles talk about Mac OS X 10.11 or earlier, or specifically Macbook Pro Apple Silicon processors.
I have uninstalled and reinstalled it and the Tools package several times.
I have checked the Security & Privacy panel, but there is no notification asking for acceptance.
The Yamaha USB driver appears in the Applications folder.
Is this a compatibility issue with Mac OS X 11.6 that you are currently working on?
So, in case anyone else encounters this, I’ve rectified it.
My UR44 was missing from Audio MIDI Setup on my Macbook Pro.
I had already followed this article without success:
Mac OS X wasn’t allowing the USB driver extension, but also wasn’t creating an alert for me to allow the extension in the Security & Privacy panel in System Preferences.
Running this command in Terminal allowed the extension temporarily until the laptop was restarted: sudo touch /Library/Extensions
The solution was to disable the System Integrity Protection:
Uninstall Yamaha USB Driver.
Restart/Power on your Mac (Apple > Restart / Shut Down).
Recovery Mode: Hold down Command-R until the Mac logo appears
Enter Password
Wait for OS X to boot into the OS X Utilities window.
Run this command in Terminal: csrutil disable
Restart.
Reinstall Yamaha USB Driver 3.05
Restart
Open System Preferences → Security & Privacy
Unlock changes
Reauthorise Yamaha Corporation extension.
Followed your instructions, disabled the System Integrity Protection, but still unable to install the latest Yamaha Steinberg USB driver.
The message I still get is:
“Yamaha Steinberg USB Driver can’t be installed on this computer.”
Interestingly, now my UR22mkII is showing in the Audio Setup menu in the Audio Midi settings window, so I can use it or add it to an Agregate device.
I am left with the question, should I re-enable the System Integrity Protection?
I´m running OS 13.6 Ventura and have downloaded Steinberg USB driver 3.1.6
spent the last two days restarting my computer installing and uninstalling this driver. after scavenging the net for solutions.
Your solution helped me get bac the ALLOW button and I DID get the Kernel Cache Rebuilding message. Restarted after that and all yet the driver still does not show up correctly in AUDIO MIDI , just a blue generic usb icon named AG06 and no signal on either channel.
This is crazy. everything is new and updated and steinberg offers no help online.
Until this is fixed consider this:
Go to Utility → Advanced → switch from Vendor (Yamaha / Steinberg) to Generic.
Reboot (in my case m8x) it will show up in Mac Input / Output without rebooting. your Mac.
Since the original post I have upgraded to a new MacBook Pro with OS X 13.6 Ventura and the UR44 has worked with it.
So it is possible to get it working, but I did not encounter the extra hurdle you have, so I’m unable to say what I did differently when installing.
Though I do now receive a notification saying that legacy extensions won’t be supported by the next OS update, so I have not updated beyond Ventura 13.6.
Hi @Zaakkk ,
after following @Adrian_Diery suggestions I was in your same situation (“Yamaha Steinberg USB Driver can’t be installed on this computer”), now I’ve tryed to install an older driver ( V1.9.10 ) and it worked!
