I would like to know which version of Java I have installed on my Mac, since the software I want to use will only run on Java 7 or higher.
How can I check (and update) ?
Java is a free software platform which is operation system independent (so Mac & PC) created and maintained by Oracle. Despite it always having been a very reliable way of making cross platform games & applications, Apple has restricted the use of Java to ‘only when needed’ by default in the latest versions of OSX and macOS, because of the security risks involved in using Java and similar software that can run autonomously on your Mac next to macOS.
To find out which version of Java you have installed, do the online check that’s on this official website :
Just follow the instructions given and the result of the check will be shown : you will either have the latest version installed, or you won’t… in that case update instructions will guide you to getting the latest version available for your Mac.
