I just installed Mac Security Update 2014-003 and the blocked plug in problem happened again. As I have done multiple times in the past, I copied an new Xprotect.meta.plist (from earlier in this thread) file into the /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources folder. This time the fix did not work. Does anyone have a fix for this recurring problem? Do I need to to install Java for OS Update? I have done some looking around and found the following. I found this, I am running mac os x 10.8.3.As apple disabled java plugins older than 1.7.11 i am getting blocked plug-in for java 1.7.7 plugin.But My Applications work with java 1.7.7 plugin only as there is gh security in later versions of java 1.7.09 my applets wont work with gher java plugin of 1.7.09.So have to make work/enable java plug-in 1.7.7 in mac os x 10.8.3.I tried to do change in XProtect.meta.plist.But it is not allowing to login as root give write access. Everytng worked fine with mac os x 10.8.2.After upgrading to mac os x 10.8.3 only i am getting ts problem.Can anyone please help me to resolve ts.It would be great if anyone have solution or workaround for this. on Likely Answer.
