Aquarium 4K Support
Aquarium 4K isn't working right. I am running macOS Lion 10.7.5Please install the 10.7.5 supplemental update, this fixes an issue with Sandboxing that may affect Macs running 10.7.5.
Aquarium 4K isn't working right. How can I fully uninstall it?
In most cases, removing Aquarium 4K from the Applications folder is not necessary. What is important, is to reset the Preferences. First off, quit Aquarium 4K. Then, open Terminal.app (/Applications/Utilities/Terminal.app) then type in the following command:
defaults delete com.machsoftwaredesign.aquarium4kmacos
And press Return. That should reset Aquarium 4K back to Factory settings.
