Apple's Java was "incomplete" in that it depended on some "special" files and so developers had to clone that file in a particular way in order to build desktop apps that were truly standalone. Java on the desktop is safe - it's in the browser where there can be issues, but that's also true of just about ANY browser technology. The main point is that Java 6 by Apple and Java 7+ (8, and soon 9) from Oracle deliberately live in different parts of the OS so that they won't ever conflict by trying to share dependencies, libraries, files, etc. I've written this up a gazillion times, but probably Mike covered everything - am too tired after so many BART delays tonight due to police actions and the like. You can use it to check for the latest build and download the update if old. JRE 8 only installs a Java Control Panel in System Preferences. Unless you want this, make sure you uncheck that option when installing. Unfortunately, the JRE 8 installer wants to add a setting that makes Yahoo! Your default search engine. Many web sites and some apps require it though you can set browsers to ask before using. The latest JRE 8 is downloaded from Oracle only. You want the 2015-001 version here.Ģ014-001 works in Yosemite and Mavericks only 2015-001 supersedes it. Otherwise, you want the JRE.Īlthough Apple cannot include it, they released a tweaked build that lets 32bit apps that require JRE 6 to run in Sierra and backwards (and High Sierra, too). The error messages usually say “Java Toolkit.” and are wrong unless you are a Java developer, then download the JDK.
JRE (Java Runtime Environment) 6 is 32 bit only. Understand that and the rest of this makes sense. For that reason, neither Apple nor Microsoft are allowed to include it in the OS (with Apple, that means Mavericks on). SUN was bought by Oracle who now makes the rules concerning Java.
