@mjtsai You have a supported app that runs on Tiger still?
Michael Tsai ‏@mjtsai 26 Sep 2013

@kevinhoctor No. Within the past few months, all my apps now require 10.5 or 10.6. But lots of people run old versions on old OS versions.

@mjtsai Makes sense. We have those as well, but I’m not tracking their specs so I have no numbers.
Michael Tsai ‏@mjtsai 26 Sep 2013

@kevinhoctor Will be interesting to see what happens to the 10.6 numbers when 10.9 ships. So far they are still almost as high as 10.7.
kevinwalzer ‏@kevinwalzer 26 Sep 2013

@mjtsai @kevinhoctor Makes me wonder if there's any value in moving to 10.9...
Michael Tsai ‏@mjtsai 26 Sep 2013

@kevinwalzer Do you really have a choice?
kevinwalzer ‏@kevinwalzer 26 Sep 2013

@mjtsai Well, I'm still on Lion. Don't seem to have missed much with ML. But I think I will update to 10.9 anyway...
