Pygame and Java JDK 13 installation troubles
Apt used to be a command coming with the Java Development Kit around Java 6. 
Java 6 is also the latest 32-bit version provided by Apple but that doesn’t run on the newest version of Mac OS. 
I think you should look for a newer version of pygame compatible with your system.
Good morning guys,
trying to install the Pygame library on my MacBook Pro...
I encountered some issues that I'm sure you're able to help me with!

First of all I installed the last Python version (3.7.4)
Than I tried to install via pip the Pygame library, but the process
was unsuccessful due to the lack of a Java JKD 13.
I downloaded and installed the last JDK 13 version (Jdk-13_osx-x64)
and this process appeared to be successful.

Trying again to finally install the Pygame library an error occurred:

Unable to locate an executable at "/Library/Java/JavaVirtualMachines/jdk-13.jdk/Contents/Home/bin/apt

Can anyone of you guys help me???
Thanks prior!
