v1.0.1

Install

Requires macOS 12 or later. Quit any audio apps first.

1. Download OpenSL3-1.0.1.zip from the assets below.
2. Unzip it and remove the download quarantine, so macOS will load the driver:

   cd ~/Downloads
   unzip OpenSL3-1.0.1.zip
   xattr -dr com.apple.quarantine SL3Device.driver

   (If your browser already unzipped it, skip the unzip line.)
3. Move the driver into place and restart the audio service:

   sudo mv SL3Device.driver /Library/Audio/Plug-Ins/HAL/
   sudo chown -R root:wheel /Library/Audio/Plug-Ins/HAL/SL3Device.driver && sudo killall coreaudiod

4. Plug in the SL3. Rane SL3 appears in Audio MIDI Setup and in your apps.

Upgrade

Same as installing, but remove the old driver first. Moving the new one onto an installed driver would put it inside the old bundle rather than replacing it.

1. Download OpenSL3-1.0.1.zip from the assets below.
2. Unzip it and remove the download quarantine:

   cd ~/Downloads
   unzip OpenSL3-1.0.1.zip
   xattr -dr com.apple.quarantine SL3Device.driver

3. Remove the old driver, move the new one into place and restart the audio service:

   sudo rm -rf /Library/Audio/Plug-Ins/HAL/SL3Device.driver
   sudo mv SL3Device.driver /Library/Audio/Plug-Ins/HAL/
   sudo chown -R root:wheel /Library/Audio/Plug-Ins/HAL/SL3Device.driver && sudo killall coreaudiod

Uninstall

sudo rm -rf /Library/Audio/Plug-Ins/HAL/SL3Device.driver && sudo killall coreaudiod

Changes
