Sparkle requires Mac OS X 10.9 Mavericks or later and runs smoothly on the latest 10.10 Yosemite, 10.11 El Capitan and 10.12 Sierra. 

Websites generated with Sparkle have been tested in a variety of scenarios. 

Specifically Sparkle websites work on all current versions of the major browsers of each platform: 



Microsoft Internet Explorer and Microsoft Edge

Google Chrome

and the mobile browsers: 

  • Safari on iOS
  • The Android “Browser” (up to Android 4.x)
  • Google Chrome on Android

Compatibility and visuals are degraded in older versions, but this is very minor for browsers shipped in the past 3 years. 

Sparkle has specific provisions and workarounds to make sites work on Internet Explorer back to version 8 with a visual degradation for some features, specifically non-opaque elements in some cases and partially transparent gradients.

Updated for Sparkle 2.2
