Installation

Download

  1. Download from the main page (click on the green combobox "Clone or download" and select "Download ZIP"). DO NOT RENAME the downloaded file (bug in some un-zippers #100).

  2. Unzip the driver (double click)

Prepare the machine

First time installation only: prepare your machine to take developer kernel extensions.

On Big Sur:

  1. reboot in recovery mode (hold cmd-R while booting)
  2. go to utilities-terminal
  3. enter this command: csrutil disable
  4. reboot your machine
  5. run the installer
  6. A popup appears, click on "open Securiy Preferences"
  7. In security & privacy preferences that opened, at the bottom "System software from developer 'Unidentified - EMUUSBAudio' has been updated". click on "Allow"

On Catalina::

  1. reboot in recovery mode (hold cmd-R while booting)
  2. go to utilities-terminal
  3. enter this command: csrutil disable
  4. reboot your machine
  5. under "System Preferences > Security and Privacy > Privacy" grant full disk access to terminal and the driver installer
  6. In a terminal do sudo mount -uw /

On El Capitan .. Mojave:

  1. reboot in recovery mode (hold cmd-R while booting)
  2. go to utilities-terminal
  3. enter this command: csrutil enable --without kext
  4. reboot your machine

On Yosemite and earlier:

  1. open a terminal and enter this command: sudo nvram boot-args="kext-dev-mode=1"
  2. reboot your machine.

Allow apps to run

On El Capitan and above you may have to enable running 3rd-party applications before you can run the Installer and the Control Panel:
  1. On Sierra you may first have to enable the "Anywhere" button in the Security&Privacy panel. Execute sudo spctl --master-disable in a terminal.
  2. Go into System Preferences->Security&Privacy
  3. Under the General tab, change Allow Downloaded Apps From to Anywhere
  4. Start the installer or Control Panel

Install the driver

After download and preparation, you can install the driver:

  1. Turn off the EMU device
  2. Run the install script (e.g. double click it) and follow the instructions.

If you like you can also copy the control panel into your applications directory. You also have to copy the Skins folder along with the app.

NOTE: After the install, it takes OSX up to a few minutes to incorporate the driver into the kernel.

Usage

  1. Install the driver as above
  2. Use the EMU control panel to select the sample rate you want
  3. Select the EMU input in your favourite tool (e.g., Audacity)
  4. Make your recording

Uninstall

This is the procedure to completely remove the driver. WARNING. Be very careful with the rm -rf, if you give it the wrong arguments you may remove essential system files.

  1. Turn off the EMU.
  2. sudo rm -rf /System/Library/Extensions/EMUUSBAudio.kext (you need admin password).
  3. sudo rm -rf /Library/Audio/MIDI\ Drivers/EMUMIDIDriver.plugin (you need admin password).
  4. delete the control panel (if you installed it).

Revert to original (Creative) driver

Download and install the original EMU driver provided by E-MU. Notice that this driver is not working on modern OSX.

Hackintosh Notes

The notes here are from users, I can not verify these myself.

The serial port has to be disabled in the bios. If enabled, the system detects wrong IRQ directions, the driver entries in conflict, which results in system malfunction when you power on your audio interface. (#134)
