UAD Apollo Twin Not Showing Up in Logic Pro: The macOS Privacy & Security Fix

A composer’s Apollo Twin was connected and lit up, but macOS hadn’t been allowed to load Universal Audio’s driver software, so UA’s own software couldn’t find it.

He got in touch because he couldn’t get his guitar or mic into Logic Pro. In his message he said he couldn’t see any input signal in Console, and the output seemed to be cutting in and out.

Can the Mac see it?

He booked a session online and we connected on AnyDesk so I could see his Mac. I started by checking whether the Mac could see the Apollo at all. In System Report (Apple menu, top left), the Apollo Twin was showing as an active device on his Thunderbolt ports, so the Mac could see the hardware.

Then I opened UAD Console and UAD Meter & Control Panel, and Meter & Control Panel said no device was connected. With System Report showing the Apollo as connected, I thought this was more likely to be a software problem than a hardware one.

Privacy & Security

I did a bit of research, and an article on Universal Audio’s site suggested macOS might not be allowing UA’s system extension. So I opened his System Settings, went to Privacy & Security and scrolled down.

There was a message saying system software from developer Universal Audio had been updated, with an Allow button underneath.

macOS Privacy & Security, Security section: System software from developer Universal Audio has been updated, with an Allow button. — The message on his Mac, part way down Privacy & Security. Nothing worked until Allow (boxed) was clicked.

The UAD software was installed, but macOS hadn’t been allowed to load UA’s driver software, so the driver wasn’t running. The message sits part way down Privacy & Security, where it’s easy to miss.

I clicked Allow, and the Mac said it needed to restart. After the restart Console loaded properly and Meter & Control Panel showed the Apollo Twin as connected.

Before calling it done I wanted to be sure he could record his guitar and mic in Logic, and that turned up a second problem. I’ve written up the second part of this session separately, in getting the signal from Console into Logic.

On Windows 11 instead? A first-generation Apollo Twin USB that won’t show up as a Windows sound device is a different problem: Apollo Twin USB not recognised on Windows 11.

When System Report shows your Apollo but UA’s software says there’s no device, Privacy & Security is the first place I’d look for an Allow button.

Paul reinstalled all my lost sample libraries, streamlined the storage on my computer so it works faster and fixed my corrupted disk. it took us a couple of sessions and he was friendly and patient throughout. He never made me feel stupid and never over-explained stuff I already knew - in fact he boosted my confidence. Would highly recommend. I've put him on speed dial!

could understand. I am a very happy song writer once again thanks to Paul! Will be using Paul again in the future and highly recommend. Thanks Paul.

Honestly, if you're in any way stuck in a creative block because of the gear you have, you've more questions than answers about what the best setup should be for your flow, or even if you have very nuanced problems in your DAW/with your gear, the service Paul provides is second to none. Besides being an extremely nice guy, he knows his stuff and takes the time to understand what you want to get out of each session and makes sure all is good to go! Can't recommend him enough!

 Trustindex verifies that the original source of the review is Google. Paul provided as stellar service, worth every penny. I came to him with a genuine issue that was affecting my Logic Pro 11 album project regarding drums and midi maps and he solved my problem most efficiently.  He was patient, courteous, quick thinking and highly knowledgeable. I will certainly consider using the service again and thoroughly recommend Audio Support -
Thank you Paul - you are a star :)

Super knowledgeable, friendly, speaks in easy to understand terms.
Paul is helping us DAW newbies get in the game. Paul got my lost plugin files working again as well as showed me how to find missing wave files for projects that were loading incorrectly. Keep this man on speed dial.

 Trustindex verifies that the original source of the review is Google. Paul fixed in around half an hour some midi keyboard/controller problems I have been trying to solve but have had to live with for around two years! He is very knowledgeable and patient and the Any Desk link worked perfectly. I wish I had found his website sooner and wouldn't hesitate to call on his services again.

My Apollo Solo was working earlier in the week. Now no mic or line signal reaches Logic at all, and nothing has changed. I've spent two days trying everything I know. What's wrong?

Why do my PreSonus StudioLive faders control the same Logic Pro channels?

Why does my expensive microphone sound distorted and bad?

I've just bought a record player and connected it to my studio monitors with a cable, but it sounds distorted and there's hum and a lot of static. When I tried Bluetooth instead it connected, but the volume is incredibly low. Can you come and sort it out?
