I have this installed on every Mac I have, but the latest version (1.5.0) is having problems whenever I try to wake my Macs from the screensaver mode. It goes into a strange freeze mode and I can't login or get out of the screensaver mode. This isn't a problem with one of my Macs running the latest version of MacOS and still running version 1.4.6 of Aerial.
Astounding. A joy to watch. The only screensaver. Posh-posh to all those others. It's been running brilliantly on Mojave since v1.4beta. Just note that you must Quit System Preferences after you install or update it in order for its 'Screen Saver Options' to work. Then enjoy.
I was recommended to try this app by more than one friends of mine, so I tried. It's fine, indeed. I've upgraded to Sierra and installed Aerial after that. Only the first launch was a bit slow, then it worked smoothly.
