1. Check on your mac by take a look into this path "/Library/Java/Home", if inside "Home" folder contain "bin/java" execute file, it's be ok. If not please download and install Java JDK.

1.2

2. Then open Terminal and type "java -version" and press "Enter", Let's see your java version, it's be ok.

3. Then type "nano -e .bash_profile" and press "Enter", Let's see on this line.

export JAVA_HOME=$(/usr/libexec/java_home)

change it to be as below

export JAVA_HOME=$(/Library/Java/Home)

4. Press "Control + X", then press "Y" and after that press "Enter", the .bash_profile was saved.

5. On Unreal Editor, Repacking again by goto

6. Choose default your project folder and click "Open", then the compile processing, just wait until the log told you "BUILD SUCCESSFUL".

It's work :)
