Maple 18 retina resolution

Is there any way to optimize Maple 18 resolution to retina resolution?

At the moment "Open in low resolution" is locked when clicking "Get info" for Maple18.app.

I've tried the easy way told on the internet for Microsoft Word by adding some lines at the bottom in Info.plist.

This is not a solution.

I've also tried "Retinizer", this will neither help solving the resolution problem for the text in Maple 18.

Anyone??

Thanks in advance

 

Thanks for fast answering.
