MAC OS will not load 10.5.6

Question

I am trying to install the new Safari Beta and I had to update my OS so I did that but getting an error message and it will not install.
I have searched the web and forums and have not come across my specific problem./
Any help is appreciated.

Answer 1

I did software updates 3 times and nothing ...
• Do you mean you applied the same update three times? If so, how?
• Do you mean you used the *Software Update application* (which tells you about new updates automatically) or do you mean you went to http://support.apple.com/downloads/ & downloaded the 10.5.6 update manually, then ran it?
• What does "nothing" mean?
I know it is a chore, but you must be very, very specific about what you have done. Remember, we aren't there with you & can't see which applications or procedures you have used. Without that, we can only give you general advice, which may be more confusing than helpful. For example:
The error usually means the update is corrupt, but what to do about it depends on how you got it. The typical solution if you got it through the Software Update application is to download & apply it manually because if SU thinks that update is already installed, it won't appear again in that app's choices.
You have two choices for a manual download, the Mac OS X 10.5.6 Combo Update & the smaller Mac OS X 10.5.6 Update, sometimes known as a "delta" because it will only update from one minor version of the OS to the next (like 10.5.5 to 10.5.6).
Combo updates are much larger than deltas but have the benefit of being able to be applied as many times as you want & since they include full versions of every OS file that has changed since the first release they can sometimes be a viable substitute for reinstalling an OS that has corrupted files. The downside is that if you are having some problem downloading clean versions of updaters, a combo's very large size makes it much harder to get a good copy.
