I have a Retina Display and Eclipse looks blurry. How can I fix it?
You need to tell Mac OS that Eclipse is high-resolution capable.
Right-click on the Eclipse.app and choose “Show package contents”
Open Contents/Info.plist in an editor
Add the following at the end of the file, just before the closing tags. It should look like this:
Move the Eclipse.app to a new folder (to clear OS X’s cache of the Info.plist), then move it back to the old folder.
Launch Eclipse
