You can install Aperture Plugins manually, Victoria.
Copy them from your MacBook pro to the corresponding folder on your other Mac.
My Aperture plug-ins are installed in one of the Library folders, either in the top level Library folder on the system volume or in the user library. Check these folders for plug-ins and copy them over:
- The user Library: ~/Library/Application Support/Aperture/Plug-Ins/Edit/
- The system level Library: /Library/Application Support/Aperture/Plug-Ins/Edit/
The menu item "Aperture Plugins" used to link to a page, where you could purchase plug-ins. This page no longer exists. But if you launch Aurora HDR, for example, and use the command Aurora HDR > Install Plug-ins, it will ask you, if you want to install the plug-in for Aperture.
