[Solved] system requirements for Mac

Is it necessary for users to have QuickTime 7 or later if we did not use QuickTime video in our screensaver animation?

Also, do users need Safari 5 with JavaScript enabled for the screensaver to work? Does the screensaver need access to this browser for some reason?

Thanks for your help!

For best results, we recommend that you stick with the system requirements as shown here: http://iscreensaver.com/requirements.shtml

One note: Safari 5 is not available on Mac OS X 10.4, so those legacy systems can only use Safari 4.

iScreensaver does not use Safari per se, but it does use the WebKit libraries on which Safari is based.

The type of content you use matters:

  • Movies & Audio are rendered either with QuickTime or with WebKit.
  • Flash (SWF) is rendered via the Flash Player Plugin under WebKit.
  • Images are rendered via OpenGL.

For Windows Operating System, the rules are the basically the same except replace “WebKit” with “IE”.

It sounds like you have a situation in mind? if you ask about that setup, we can offer more specific advice.

Thanks for your response! A couple of questions:

  1. Is Safari 5 available on Mac OS X 10.4.11?

  2. If our content is purely a PNG image animated within iScreensaver, will the users still need the screensaver to be rendered by QuickTime or WebKit? (We are seeing if we can leave any of the System Requirements off of the description for our users.)

Appreciate your help! :slight_smile:

  1. No, the latest Safari on 10.4.11 seems to be 4.x.
  2. PNGs would be rendered by OpenGL, so you don’t need quicktime. However, on Macs quicktime is built in, so it’s pretty much guaranteed to be there. The max quicktime version on 10.4.11 is 7.6.
