Hello, I’m stuck trying to set up MetaGrid Pro (using the Logic Pro Grid) with the new Logic Pro 12.0. Perhaps it’s not possible yet; otherwise, maybe there’s something I’m missing.
I have Logic activated in the MetaServer setup and copied the Logic Metasystem.bundle file into “MIDI Device Plug-ins.” However, I can’t find any MetaGrid device to install in the application (under Control surfaces/setup/add a new surface).
I’m running MetaGrid Pro 1.6.16 on both my MacBook Pro (Sequoia 15.7.3) and my iPad Air (iPadOS 26.2.1). My MetaServer version is 5.3.3. In general, my device does seem to be connected to the server, since commands in the Finder via MetaGrid are executed. However, it’s not communicating with Logic, and I don’t know how to get it to work.
No need to install the Logic bundle - since some versions ago we talk to Logic Pro directly through Apple Script. Remove the device, make sure MetaServer has got the permissions for Logic Pro :
Thank you. However, I still couldn’t get it working. In the list of permissions for MetaServer under Privacy & Security/Automation, I only see System Events and Keyboard Maestro. I already tried closing MetaServer, manually resetting the MetaServer permissions via tccutil, and then starting it up again. Still, only System Events and Keyboard Maestro request permissions, not Logic Pro. I can’t get it to appear in this list. Is there a way to force it?
Obviously, I don’t know how MetaServer works under the hood, so I can only guess. I should probably add that I’m using the Apple Creator Studio version of Logic Pro 12, which might have a different identifier (com.apple.mobilelogic). So maybe MetaServer isn’t actually trying to automate this specific version, which is why I’m not being asked to grant it permissions in the first place?
