I’ve installed iScreensaver 6.9.0 on iMac late 2017 running Ventura. After loading 119 photos (of elephants) to create 'Elephant Magic.isc", clicking the Installer button brings up a passive Install screen where 'Install" button is dimmed and inactive.
When using the ‘Preview’ button, the photos cycle on screen but with warning
“This screensaver is not licensed for distribution. Please visit iScreensaver.com for more information.”
After reading that OS section, I note that 500MB free space is required: internal disk has 244GB free.
Can anyone advise what I am missing, please?
