Bio7 2.7 Retina-Display Fix for MacOSX


I recently discovered on a high dpi display (Retina-Display) enabled 13’’ notebook that the latest release of Bio7 for MacOSX is not displayed in high dpi but in a lower resolution which makes text and icons blurry (scaled) and unnecessary strains the eyes when editing R scripts with the R editor.

So I uploaded a new, fixed version for MacOSX.

However, to fix an already downloaded version of Bio7 you have to open open the ‘/’ file with a text editor (right-click on, execute ‘Show Package Contents’ and open ‘/Contents/Info.plist’) and add the following lines before the </dict> tag:


In addition to update the Info.plist file for the Operating System you have to open the Terminal (in ‘Applications/Utilities’) and execute the following command (default install directory – shell command is one line!):

/System/Library/Frameworks/CoreServices.framework/Frameworks/LaunchServices.framework/Support/lsregister -v -f /Applications/

Here some screenshots from before and after the fix was applied on a Retina-Display (zoom in for details):



An updated version with the fix already applied can be downloaded here
