Font smoothing on Mac OS X 10.4.7
Michael Tsai writes: Maybe it’s just my imagination, but I think the font smoothing looks a bit better in 10.4.7. I use the Strong style, and the letters look a bit darker and less colored to me.
It's not imagination. I don't know what, if any, changes were made to the antialiasing algorithms, but I do know that 10.4.7 fixed a bug with sub-pixel text antialiasing not working on Intel machines. So perhaps that explains (some of) the observed effects.
(And thanks to Apple for fixing the bug!)
