      In this pass few weeks Kernel Panic causes when I playing Minecraft. I tested this on different version as shown and finally I found the reason in log. If I minimise Minecraft or change to other desktop ( such as open safari ), after a "Saving and pausing game" log shown, there will be a warning look like this : 

      [Server thread/WARN]: Can't keep up! Is the server overloaded? Running 2887ms or 57 ticks behind 

      sometimes it is more than 4k ms or 98 ticks. Meanwhile my CPU temperature is higher than 60`C. 


      I have attach some log and the crash report of the OS and the kernel panic.  

      What I expected to happen was...:
      I expected the game pause. 

      What actually happened was...:
      Sometimes it just crash but mostly cause my Mac Kernel Panic. 

      Steps to Reproduce:
      1. Download a new Minecraft launcher 
      2. Download and play 1.14 or 1.13.2 or 1.13 or 19w14b (or other which I have not test)
      3. Open a single player game ( new map or old map both could reproduce)

      4. In a map, minimise Minecraft or change to other desktop
