Recently I purchased a MacBook Pro with Retina display and believe me Apple has done an incredible job with the next-gen MacBook Pro. The Retina display is a powerhouse. Almost everything else in native apps and photos looks amazingly crisp and clear on the Retina display. But for me as a developer when I started Eclipse first time, retina UI was not supporting Eclipse display very well. So here is the workaround to update UI:
Go to Contents->Info.plist by clicking on “Show package contents” on the Eclipse.app. Then Just above
</dict>
</plist>Place this:
<key>NSHighResolutionCapable</key>
<true/>Then, log out and restart the Eclipse. This also works for Aptana as well as for Titanium Studio and in general for all IDEs that are built on top of Eclipse.
