Laggy/Slow LightBurn on 4K monitor in Mac

[odczynnik (Jakub)]

Hello All!

There was one Topic with laggy LightBurn, with 5Hz refresh rate when trying to move something on the sketch. For me the problem was with high resolution on 4K monitor.

There are 2 solutions:

1. For systems up to 12.5, you click “get info…” on the LigthBurn icon and set up Low resolution option.

2. For system 12.6 and up, Low Resolution option is missing. You need to go to “Show package contents” and then enter to the Content and you will find Info.plist. Open it with some text editor and on the end before

</dict> and </plist>

add :

<key>NSHighResolutionCapable</key> <false/>

This will change the mode to Low res mode and LightBurn will much much more responsive.

This is how the end go my Info.plist file looks like, you will see where I add this Low Res line:

</dict>
 		</array>
 		<key>NSHighResolutionCapable</key>          <false/>
 	</dict>
 </plist>
