Java 6 from Apple
Apple has provided a version of Java 6 that installs properly on Yosemite. You can download and install that version. Click here to visit the download page on Apple’s website. It’c conceivable that some programs or websites might be looking for elements of Java 6 to confirm that Java is present. Even if you have newer versions of Java (such as 7 or 8) you may still get a message indicating you need Java if you don’t have 6 installed.
Safari Quick Fix
Follow these instructions for a quick fix to this issue:
- Begin with all programs closed. You may want to just restart your computer to ensure you begin fresh.
- Using the Yosemite Safari browser, visit the Java verify page here:
- This should cause Safari to invoke a launch of the Java update.
- Then, perhaps before you can press the Install Update button, another window will open to confirm the installation of the Java update. This is the dialog box to confirm the Java Detection you requested in step #2 above.
- Click Run. Then click Install Update in the other window. You may be prompted for your username and password.
- You will then see the series of dialog boxes shown below. Click the appropriate buttons to continue and then restart any programs that use Java.
This process will update Java for all Yosemite programs that are able to use the updated Java.

However, if you install Java 8, the necessary Java 7 might not install because the installation will identify a newer version of Java.

Double-click on the downloaded file and follow the on-screen instructions to install Java.
Once you download Java 8 Update 25, you won’t be able to install Java 7 Update 71 (see message below). So, you may want to directly install Java 7 instead of Java 8, since some programs may look for 7 and not recognize 8 yet.
