Hi everyone, Just follow the steps below: Right click on SQL Developer in the dock and choose Options | Show in Finder Right click on SQLDeveloper.app and choose "Show Package Contents" Double click on Contents and then MacOS Go to Oracle's site and download JDK 1.8 JRE Unzip it and copy the directory into the MacOS directory Open sqldeveloper.sh in any text editor. I commented out everything in the file and pasted in the following: export PATH=/Applications/SQLDeveloper.app/Contents/MacOS/jre1.8.0_251.jre/Contents/Home/bin:$PATH export JAVA_HOME=/Applications/SQLDeveloper.app/Contents/MacOS/jre1.8.0_251.jre/Contents/Home /Applications/SQLDeveloper.app/Contents/Resources/sqldeveloper/sqldeveloper/bin/sqldeveloper so now sqldeveloper.sh looks like this: #!/bin/bash TMP_PATH=/usr/libexec/java_home -F -v 1.8 if [ -z "$TMP_PATH" ] ; then TMP_PATH=/usr/libexec/java_home -F -v 9 #TMP_PATH='/Applications/SQLDeveloper.app/Contents/MacOS/jre-9.0.4.jre/Contents/Home' if [ -z "$TMP_PATH" ] ; then osascript -e 'tell app "System Events" to display dialog "SQL Developer requires a minimum of Java 8. \nJava 8 can be downloaded from:\n ... exit 1 fi fi # export JAVA_HOME=$TMP_PATH # if [[ -f $HOME/.sqldeveloper/19.1.0/env.sh ]]; then source "$HOME/.sqldeveloper/19.1.0/env.sh" /dev/null elif [[ -f $HOME/.sqldeveloper/env.sh ]]; then source "$HOME/.sqldeveloper/env.sh"  /dev/null fi # here="${0%/*}" cd "${here}" cd ../Resources/sqldeveloper/sqldeveloper/bin bash ./sqldeveloper /dev/null export PATH=/Applications/SQLDeveloper.app/Contents/MacOS/jre1.8.0_251.jre/Contents/Home/bin:$PATH export JAVA_HOME=/Applications/SQLDeveloper.app/Contents/MacOS/jre1.8.0_251.jre/Contents/Home /Applications/SQLDeveloper.app/Contents/Resources/sqldeveloper/sqldeveloper/bin/sqldeveloper 7. Save sqldeveloper.sh Now run it and you should get the splash screen.
