I need Java back for work. Can I and should I reinstall, or can Apple still block it? I didn't do a software update, but I can't run any Java on my mac book pro today. I read the Apple is blocking it and even Homeland Security is warning against using Java.

MacBook Pro, Mac OS X (10.6.8)

    The last Java update from Apple (6u37) for 10.6.8 was secure.  Even Homeland Security does not have a warning against this version, just Java 7.


    Apple in its infinite wisdom decided unilaterally what was best for us.  They should have asked us if we wanted it blocked  instead of a unilateral decision because there are those of us who cannot use Java 7 and need Java 6 to function in our businesses.

    OK.  I have a fix for you all that seems to work especially if you need Java 6u37 working on any computer Apple disabled it on.  This will work best on 10.6 but can work on 10.7/10.8 as well.

    Do not attempt this if you do not know what you are doing.

    I will not be held responsible for your system if it stops working or you expose yourself to a virus.  If you are a novice user, you attempt to do this, and something goes wrong, remember you were warned.




    Using whatever editor you want at command line as root or using sudo, you will need to edit:

    /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources/XProtect.meta.p list




















    And best of all, change:


    <string>Thu, 31 Jan 2014 16:55:59 GMT</string>


    To any date in the future.  (Bad programming on Apple's part but repreive for those of us who have to support archaic Oracle based systems that won't work under Java 7+.)  It won't update again until after the date you put in there.


    DO NOT Delete any of the lines that have to do with version number because it will allow older versions of Java, which are not secure, to run.  I would also not recommend that you change the date too far ahead if you are on 10.7/10.8 and are running Java 7 because the security holes in Java 7 are horrible.

    Yeah, use at own risk because it opens you up to viruses and hackers.  That is an outdated and unsecure version of Java 6.  Installing any version of Java is not going to fix what Apple did anyways.  See my fix above.  That fixes it.  But you have to be running the secure Java Update 11 not the unsecure Java Update 10 like you have linked to.

    This was the update on the Apple site. I don't use Java regardless of the situation. I always have the the sender send it in a different format.   Sorry I'm not a Java fan, as some people seem to be. If I can't open it, then I don't want to.

    That was the description of an update (which Apple yanked for security reasons) and if you had actually looked in the Downloads section of Support, you would have found the right one.  Please, if you aren't sure, don't give the advise without thorough research, especially if you don't even use the product.  As a Mac tech, nothing grates on me more than bad advise given when the right answer can be easily found or be given by someone who deals with that product on a daily basis.

    Oracle on Friday February 1 released a new version reportedly addressing vulnerabilities seen with the last build.

    Apple disabled Java 7 through the OS X XProtect anti-malware system, requiring users to have at least version "1.7.0_10-b19" installed on their Macs. The release dated February 1 carries the designation "1.7.0_13-b20," meeting Apple's requirements.


    Oracle "strongly recommends" applying the CPU fixes as soon as possible, saying that the latest Critical Patch Update contains 50 new security fixes across all Jave SE products.

    Java 7 updated  for 10.7-10.8


    Released Feb 1, 2013,  fixes 50+ security flaws
    http://www.esecurityplanet.com/patches/oracle-responds-to-java-security-flaws-wi th-50-fixes.html


    Download and install



    For Java versions 6 and below OS X 10.5-10.6 machines

    Apple supplies their own version of Java. For Mac OS X 10.6 and below, use the Software Update feature available under the Apple menu to check that you have the most up-to-date version of Java 6 for your Mac.

    Java SE 6 End of Public Updates
    After February 2013, Oracle will no longer post updates of Java SE 6 to its public download sites. We highly recommend downloading and installing Java 7.



    If your considering upgrading OS X from 10.6.8 to 10.8 via AppStore to run Java 7


    Be forewarned no PowerPC based programs or driver software will run any longer.


    Check here BEFORE you upgrade OS X!





    Alternatives if you must run Java 7


    If Apple disabled Java 6 in 10.6, and you can't upgrade OS X to 10.8, then your pretty much done with Java in OS X because Oracle won't issue updates for Java 6 anymore.
    However you can install Windows 7 and continue to use Java 7+ there until support for Windows 7 ends in 2020.

    Windows in BootCamp or Virtual Machine?


    If your on 10.6, I very highly recommend the free Virtualbox for the virtual machine software as it gets updates, VMFusion and Parallels have moved on with only 10.7+
