Hi I have recently downloaded the lasts version of your software 22.214.171.1246 and made our latest screensaver (called lightspeed). Im am seeing this error on macOS 10.13.4 Beta (17E139j) when the machine wakes
"Lightspeed" may affect the performace of your Mac. The developer of this app needs to update it to improve is compatibility.
I sometimes ALSO see an error when opening iScreen Designer that says the Developer needs to update their software to make sure it is compatible.
I believe your software needs to be made in 64 bit as all software needs to conform to this now. https://www.macrumors.com/2018/01/24/macos-high-sierra-32-bit-app-warning/
Please you app in 64 bit which will make a screen saver for Mac in 64bit!
