I compiled a Java/OS version spreadsheet a while back, which is relevant here: https://docs.google.com/spreadsheet/pub?key=0AkWOpXiooWpDdHhMZXFXVG9RaHhPelp2LVdfX1RMNHc&output=html Furthermore, I researched this a couple of different times in recent months. The results are part of the ImageJ FAQ: http://imagej.net/FAQ#Why_does_ImageJ_still_target_Java_6.3F As of this writing, around 11% of OS X systems still run version 10.6 Snow Leopard or older. * As of June 2014, it was ~19%. * In December 2013, it was ~25%. And OS X only has ~7% market share right now, meaning that the actual market share for 10.6 and older is only ~0.8%. Of course, none of these statistics are ImageJ-specific. A somewhat higher percentage of ImageJ users use OS X: from the weblogs of sites.imagej.net, we know that it is about 10.6% of the traffic, but the logs don't tell us the version breakdown of OS X. (We would know for certain had the usage statistics not been kiboshed.) So TL;DR: with some minimal assumptions, ~1.2% of ImageJ users still use Snow Leopard are earlier.
