Good news: SAP GUI for Java 7.30 is out. Bad news: It looks bad on MacBooks with retina display. Here is a small hack to make it retina-compatible.
Make sure that SAP GUI is not running.
Browse “/Applications/SAP Clients/SAPGUI”. Right-click “SAPGUI 7.30.app” and select “Show Package Contents”. Open “Info.plist” with TextEdit and add the following lines to the very end of the file, before the last two lines:
Save & exit.
Run “/Applications/Utilities/Terminal.app” and type the following command (modify if SAP GUI is installed elsewhere):
touch /Applications/SAP\ Clients/SAPGUI\ 7.30/SAPGUI\ 7.30.app
That’s it! You may (or may not) need to restart your Mac; but next time you run SAP GUI for Java, it will look crystal clear – utilizing the potential of your retina display.
