Feature request #11103
Updated by Denis Rouzaud over 5 years ago
Currently QGIS does not support Retina displays (HiDPI), such as on the current MacBook Pro. The application loads, but is running in a low-resolution upscaled mode which makes everything look pixelated. See attached screenshot (qgis_lowdpi.png).
The Qt blog has some information on supporting retina displays in Qt applications:
http://blog.qt.digia.com/blog/2013/04/25/retina-display-support-for-mac-os-ios-and-x11/
The first step is to add the following to the Info.plist file:
<pre>
<key>NSPrincipalClass</key>
<string>NSApplication</string>
<key>NSHighResolutionCapable</key>
<string>True</string>
</pre>
This tells the application that it's capable of HiDPI rendering, which gets text and buttons to render correctly. See attached screenshot (qgis_hidpi.png).
However, the map canvas itself, and (most) of the icons are still pixelated. To "fix" the icons, they need hi resolution versions available. The blog post discusses this a little, but I've not had any success so far in getting QGIS to recognise larger versions of the icons. The other step will be to tell the canvas to renderer at a higher DPI - no idea how to get this working.
I've asked a question on stack overflow here:

Myself (@snorfalorpagus) and Dale Kunce (@calimapnerd) have an interest getting this working:
