I have an older compiled application that is not yet running in Retina mode. Now I found the Xojo blog post Enabling Retina Support and inserted the following code into the Info.plist file as described.
<key>NSHighResolutionCapable</key>
<true/>
If I now start the program, it still appears in the low resolution. I have read that the cache of the application needs to be refresh. Therefore you should enter the following command in the macOS terminal:
sudo touch /Applications/Appname.app
However, the application still does not start in Hi-DPI mode. How do I get the desired result?
[quote=416199:@Martin Trippensee]It’s a compiled app I bought. It is a Xojo app, but I assume that this version was probably created before 2014. https://www.bkeeney.com/task-timer-5/[/quote]
Most probably is. The last update on the Mac App Store was back in 2011 so the retina switch would not work.
Check with Bob, he might have an updated version for you.
