How to tell Apple that my Cocoa app is not ready for high resolution?

Question

Apple says that either user or OS X may decide to launch a Cocoa app in magnified mode instead of framework-scaled mode:

All apps that are not Cocoa apps run in magnified mode. However, a Cocoa app can also run in magnified mode if:

• The user sets the option to open the app in low resolution (see Figure 1-7).

• The app is known to have significant issues when running in framework-scaled mode, so the system makes an exception and instead runs the app in magnified mode.

(see link)

But how the app developer can launch it magnified? Or, how to force OS X to do it?

Answer 1

You can set the property NSHighResolutionCapable to false in your Info.plist.

In XCode, that property is called High Resolution Capable.
