The A2|6 driver provided with the device has not worked since Mac OS-X Lion (10.7). I have written a replacement driver which works from Lion to present (Sierra), and hopefully beyond.
Please note, this driver is for the A26 device (2 inputs 6 outputs), not for the A62m. A driver for the A62m can be found here.
To install the driver you will need to obtain and install files as detailed below. When finished you will have the following files installed (shown with yellow shading).
Before you begin, ensure you are logged into an admin account. You can check whether your account is an admin account through Users & Groups in System Preferences. “Allow user to administer this computer” should be checked.
Download the archive from this link. When expanded it produces an A26 folder containing two files. Make sure the folder’s name is “A26” exactly. If it is not, rename it. Also ensure the A26 folder is on your desktop and not somewhere else. A step below expects to find it on the desktop with this exact name. (You may remove the folder after successful installation).
The .HEX files shown in the above image are the firmware for the A26 device. These files are copyright, so I have not included them in the zip file. They are not hard to find on the internet, for example here.If you use the above link, click on the 'Download' icon near the top-right of the page. This will download an emi26.zip file. Open (expand) the zip file, and you will find three ".HEX" files.
Please note, this website has changed its interface in the past. You might need to modify the above instructions to obtain the files.
Firstly place all three .HEX files
(loader.HEX, bitstream.HEX and firmware.HEX)
into the A26 folder on your desktop. They should not be inside another folder.
The file structure should look as follows (file sizes could vary slightly):
Provide your admin password when requested. You should see the following:
chmod 755 install.sh
Your files and folders should now reflect the picture shown at the start.
Unloading previous driver (if any)...
Installation successful. Launching driver...
That's it. No need to reboot. You will need to plug in your A26 before the driver will load.
The driver can take several seconds to upload the firmware. Between 10 and 20 seconds is typical. You can use the Sound Control Panel to check that the firmware has been uploaded successfully.
Please me if you find any mistakes with these instructions.
