I've changed some options related to font rendering by defaults write command in past (I can't recall was it lcdfilter, or something else). Now when I turn off antialiasing in system preferences font are still looks antialiased, but have less weight (see screenshots). 1. With antialiasing 2. Without antialiasing 2. With antialiasing 2. Without antialiasing

Note, I have Retina display, so, this could be normal behaviour, but I'm not certain, that's why I decided to ask about it. If this is not default behaviour (it seems to me, that fonts too heavy when antialiasing turned on), how can I rollback changed values to defaults?

You can change the amount of font smoothing with the following command:

defaults write -g AppleFontSmoothing -int [value]

[value] is a value between 0 and 3 inclusive. Requires log out and log in.

Here's a gif by Lauri showing the difference:


  • Oh, I suppose this is exactly the same command I've used, but what is actual default value? Dec 22, 2014 at 18:54
  • @Geradlus_RU 2 should be default.

  • OK, I'll try it out now. UPD I have 3 set for now. Dec 22, 2014 at 18:56
  • Well, I've changed value to 2, logged out and in, but actually there is no difference. At least I know default value now, thanks! Dec 22, 2014 at 19:07
