I just upgrade to Mavericks and had some issues. Out of all the issues, one that I get frustrated the most is Chrome browser is not displaying font like it use to be. Here are two images taken from Safari and Chrome to compare.

Chrome Browser

Safari Browser

As you can see, comparing both Safari and Chrome, fonts on Chrome are more bold. I use Chrome mostly for my development and the font use in this design is Open Sans font-weight 300.

Is this normal or there is a fix to have Chrome render the fonts more finely as Safari does?


It's not a Mavericks issue.

Google Chrome has (currently) a bad support of Webfonts.

  • Yes, I did a few search and seems like that is the case. I just don't understand is when I was on Lion, chrome render the fonts just fine. Only after update is when I notice it. I use the same chrome version on both Lion and Mavericks. – siQuang May 2 '14 at 8:31

I did some research and found that in Mavericks there was a change in system font.

The font used is Lucia Grande and it was optimized for retina in Mavericks.

If you want to change it back to ML there is a way in Terminal:

defaults write -g AppleFontSmoothing -int 1

That would change it to Lucia Grande "Light" (10.8)

  • Give this a try and still font is not rendering correct. In the meantime I just use Safari for viewing and Chrome for developing. – siQuang May 3 '14 at 3:45
  • @siQuang you will have to restart after changing the font – Ruskes May 3 '14 at 8:33
