If the UAD Meter displays Connect UA Device or No Devices Found, a UAD or Apollo device is not connected or available. First check that your device(s) are fully connected and powered on. If the issue persists, the troubleshooting suggestions below can help you get up and running with your UAD device(s).

Note: On macOS 11 Big Sur, if the Allow button is unavailable or does not load the UAD driver when clicked (causing red Driver Not Installed Correctly text to appear in the UAD Meter app window), you might need a newer UAD or Big Sur version. Visit the Driver Not Installed Correctly on macOS Big Sur article for more information.

MacOS Security

MacOS requires manual configuration steps to enable UAD software. If these steps are not done, UAD devices are not recognized.

To get the detailed configuration instructions for your Mac, first visit the Latest OS compatibility article. Then, under the macOS heading in that article, click a link to the individual compatibility article for your specific version of macOS.

Note: FireWire connections for UA devices are incompatible with macOS Big Sur. First generation (silver) Apollo models are supported with Big Sur when connected via a Thunderbolt Option Card.

Check Computer Compatibility

If you're connecting your UAD device(s) to your computer for the first time and see the "No Devices Found" text, first check to make sure that your computer is compatible with the UAD device(s) that you're using. See the system requirements for your UAD device below to make sure that your computer meets the minimum specifications:

• Apollo X Desktop System Requirements
• Apollo X Rack System Requirements
• Apollo FireWire System Requirements
• Apollo Twin & Apollo Twin MkII System Requirements
• Apollo Twin USB System Requirements
• Apollo 8 & Apollo 8p System Requirements
• Apollo 16 & Apollo 16 MkII System Requirements
• UAD-2 Satellite FireWire System Requirements
• UAD-2 Satellite USB System Requirements
• UAD-2 Satellite Thunderbolt System Requirements
• UAD-2 Satellite Thunderbolt 3 System Requirements
• UAD-2 PCIe Card System Requirements

Check Data Connection

Check the data connection on your UAD device (i.e., FireWire, Thunderbolt, or USB) to make sure that the data cable is firmly seated into the ports on both the UAD device and the computer. 

If using Thunderbolt: The Thunderbolt logo on the Thunderbolt cable must be face up when plugged into both the UAD device and the computer. If the Thunderbolt logo is not face up, then the cable is inserted upside-down, which can be done fairly easily. 

Note: On iMac computers, the Thunderbolt logo on the Thunderbolt cable should face left when looking at the back of the iMac.

Note: FireWire connections are not supported on Big Sur. First generation Apollo models may be used when connected via Thunderbolt using an installed Thunderbolt Option Card. Satellite FireWire models are unsupported.

Hardware Reset (Apollo interfaces only)

Try re-initializing your Apollo interface by doing a hardware reset. See the directions for your Apollo model below:

• Apollo Twin Hardware Reset
• Apollo Twin MkII Hardware Reset
• Apollo Twin USB Hardware Reset
• Apollo FireWire Hardware Reset
• Apollo 8 & Apollo 8p Hardware Reset
• Apollo 16 & Apollo 16 MkII Hardware Reset

Uninstall / Reinstall the UAD Software

A full uninstall of the UAD software will remove all UAD applications, drivers, preference files, etc., from your computer so you can reinstall the software like new. This can resolve "No Devices Found" and other issues. See the directions for your operating system below:

• Mac Uninstall / Reinstall
• Windows Uninstall / Reinstall
  
  

Replace Data Cable

If you're still experiencing issues after going through the troubleshooting steps above, we recommend replacing your data cable (FireWire, Thunderbolt, or USB) with a new one, or with one that you have confirmed as working by testing it with another device. Bad or defective data cables are fairly common and even relatively new cables can develop issues that will cause your device not to be recognized by your computer. 

Troubleshooting Other "Connection Error" Messages

Other general "Connection Error" messages can appear in the UAD Meter under certain conditions. All of the troubleshooting suggestions above apply to these messages as well.
