MacOS Launch Rack from Terminal

VCV Rack
1

Hi, im trying to launch Rack from a terminal window in macOS Catalina doing:

$ /Applications/Rack.app/Contents/MacOS/Rack ./mypatch.vcv

Rack opens but dosent load the patch, only a blank rack appears.

Any idea? Thanks in advance…

Are there advantages to opening it with the terminal? FWIW, it runs great on BigSur on my iMac.

For first app instance

open -a /Applications/Rack.app ~/Documents/Rack/patches/patch.vcv

for second instance or more

open -n -a /Applications/Rack.app ~/Documents/Rack/patches/patch.vcv

with more arguments, e.g. user dir in current directory

open -a /Applications/Rack.app ~/Documents/Rack/patches/patch.vcv --args -u $(pwd)

As far as I’m aware, forgetting Terminal for a moment, you can’t open Rack by double clicking on a .vcv file (unlike pretty much any other Mac application).

You need to launch Rack first, then do a File > Open.

This might be related to the problem you are experiencing when doing it through Terminal.

Working! Thank you very much :slight_smile:

cd into /Applications/Rack.app/Contents/MacOS/ and run

./Rack path/to/patch.vcv

This will run the patch in headless mode, but it’s my understanding that the modules in the patch need to support headless mode.
