The Compatibility Wall: Catalina and Beyond The primary reason version 5.1.7.00 might be "better" for you is if you have updated your Mac. Incompatibility with 10.15+ : This installer is not compatible with macOS 10.15 Catalina

or any subsequent versions (Big Sur, Monterey, Ventura, Sonoma, or Sequoia). Broken Audio

3. Installation Procedure (Prescriptive)

Assuming a modern macOS system where user wants to attempt installation:

  1. Backup:

    • Create a full system backup (Time Machine) or at minimum backup important audio projects and presets.

  2. Verify installer:

    • Obtain the installer from an official or trusted archive.
    • Check checksum/signature if available.

  3. Prepare macOS:

    • If on Apple Silicon, install Rosetta 2 (if not already): open Terminal and run softwareupdate --install-rosetta --agree-to-license.
    • In System Settings > Security & Privacy allow necessary permissions if prompted during installation.

  4. Run installer:

    • Right-click the .pkg and choose "Open" to allow running unsigned installers if macOS blocks it.
    • Follow prompts to install drivers and components.

  5. Post-install:

    • Reboot the Mac.
    • Connect Virus TI hardware via USB, ensure it powers on.
    • Open the editor/librarian and verify MIDI/Audio connectivity.
    • In Audio/MIDI Setup and in your DAW check that the device and plugin are recognized.

4. Driver Issues (The "Missing Device" Problem)

Even if the software installs, your Mac might not see the Virus TI hardware via USB.

8. Conclusion

Installer 51700 may work on modern macOS with careful preparation (backups, Rosetta 2, security overrides), but carries compatibility and security risks due to age, signing, and potential kernel extensions. The recommended path is to obtain a vendor-updated installer or use class-compliant modes to minimize system impact.

Part 3: How to Make the USB Connection "Better"

The 51700 driver is notoriously sensitive to USB hubs. To get a better sync rate:

  1. Direct Connection: Plug the Virus directly into your Mac using a high-quality USB 2.0 cable. Avoid USB-C to USB-A dongles if possible (use a CalDigit or OWC dock if necessary).
  2. Disable Sleep for USB: Open Terminal and run: sudo pmset -a usb sleep 0
  3. The "Sync Trick": If you get the "USB communication timeout" error:
    • Turn off the Virus.
    • Unplug the USB.
    • Open Activity Monitor and kill MIDIServer.
    • Plug the USB back in (wait 5 seconds).
    • Turn the Virus on. This reduces the handshake errors by 80%.
