Mac OSX Beta download
IMPORTANT NOTICE: This beta fixes a problem which prevented Dream Aquarium from running on Catalina.
HOWEVER, there are several MAJOR bugs in the Catalina OS itself (related to their screensaver engine) which seriously affect Dream Aquarium (and other screensavers).
One bug causes any mouse/keyboard events to quit the screensaver instantly, so user interactivity is impossible.
Another bug affects some machines and causes openGL screensavers to render in only one corner of the screen.
Apple is aware of these bugs but gives no ETA on when they might be fixed.
Unfortunately there's nothing we can do to work around the problem and we will
simply have to wait until Apple gets around to fixing them. We are as frustrated as you are!
Your patience is appreciated, and we are very sorry for the inconvenience.
