$ echo 'export PATH='$HOME/.jenv/bin:$PATH'' > ~/.bash_profile Next, ensure that jenv is listed as a command on your shell, if you are using bash, then run run brew upgrade)įirst, we need to install JEnv using homebrew, run the following command: The goal of this post is to show that we could do just that with Java, install a package to allow us to toggle between Java versions and set our JAVA_HOME path automatically for us just by running a few simple commands.īefore we start, ensure that you have homebrew installed and that you have updated all dependencies (ie. For those that come from NodeJS, installing a new version of Node is as easy as installing nvm and running nvm install and calling it a day.

Then we need to open and edit ist: sudo nano /Applications/UniFi.app/Contents/istĪnd add the following JVMRuntime section manually after the JVMOptions JVMRuntimeĪfter this, the UniFi Controller should run without problems.I think its fair to say that going through the process of installing Java on any machine is in of itself a bit confusing. I’m going to assume you have Adopt OpenJDK installed, preferably via Homebrew – if not, then install Homebrew and then: brew tap AdoptOpenJDK/openjdkĪfter this, you should be able to run Java runtime on your Mac – let’s get back to making UniFi Controller run.įirst, we need to link our current Java to the UniFi.app sudo ln -s /Library/Java/JavaVirtualMachines/adoptopenjdk-8.jdk/ /Applications/UniFi.app/Contents/PlugIns Starting the Unifi Controller under recent macOS versions with OpenJDK installed can cause problems, such as one of the following warnings:
