Hello Antonio,
The last day I got some complaints about the sharpness of the fonts used in browses and on buttons. If you look carefully to the sharpness of the font in a browse it is not so sharp as the font in the menu or the statusbar. Is there anything I could do about this.
I have changed the image to show the problem. On the right there is a text editor I use, on the left the program. After reading a lot on the Apple developer site I saw that my program (and all programs made with FiveMac) are not made for the Retina screen. If you rightclick on an app and click on 'show info' you see that the app is forsed to use low resolution.
