An update is required to support the new retina screen for the mac. A simple fix is to add "NSHighResolutionCapable" key and set it to true in info.plist. This allows the text to be rendered in high resolution and won't affect non-retina users.

[Jiaz]

So I tried:

<key>NSHighResolutionCapable</key>
<true/>

and

<key>NSHighResolutionCapable</key>
<string>true</string>

but none is working. What am I doing wrong?

Sorry if this seems like a stupid question, but I'm having the exact same issue (yes, tried logging out, renaming app, deleting original, etc.)

Can anyone help in where I'm going wrong?
