How to get NetBeans 12.0 to launch on Mac (MAC OS 11.0 beta / Big Sur)

On Mac (Big Sur) when I click on the Netbeans 12 icon in the doc it bounces briefly then fails to launch Netbeans.

The answer helped me launch Netbeans from the terminal. I added this change to make my dock icon launch Netbeans like before.

I changed the Netbeans config file to make it launch with the Java path:

1. Like the previous post indicates find your JDK path with this command in the Terminal

/usr/libexec/java_home -v '1.7*'

2. Now add this path to the Netbeans conf file. To do this:

• right click on the Netbeans icon in the dock and select Open in Finder
• in the smaller icon it shows right click again and select Show sources
• find the netbeans.conf file in folder Resources/NetBeans/netbeans/etc/netbeans.conf
• open this netbeans.conf file with a TextEditor or similar and find the line

#netbeans_jdkhome="/path/to/jdk"

Uncomment this line and change it for your path (the one you found in point 1) something like

netbeans_jdkhome="/Library/Java/JavaVirtualMachines/jdk-15.jdk/Contents/Home"

Save the netbeans.conf file and try and launch from the Dock icon
