How do I know if or when I should accept an update? How do I know if it is something that is behind the scenes and necessary, is it legit or just on a "need to use" basis? How do I know the difference? These are some examples of what software is currently available per my updates: Java for Mac OS X 10.5 Update 6 version 1.0 Remote Desktop Client Update version 3.3.2 Digital Camera Ray Compatib... version 2.7 Security Update 2010-001 version 1 I assume they are all OK but do I really need them? Also, the Java update listed has not been installed or opened, yet I noticed one day it was sitting in my trash can. How can it be two places at once? Why is it in the trash and in my "software update" to-do list? Why are the sizes different? The updates says the Java is 123MB but in the trash the same one is 139.1MB. Why? Thanks!
