I had one minor problem the first time I tried to run the update thru Software Update. It failed and gave me this dialogue:
So I took a look around, kinda sorta found where they were directing me, and all read/write permissions were fine. No adjustment needed. Ran it again. Worked perfectly. The only difference between the first attempt and the second was I had several applications open the first time I ran it.
"The update "Security Update 2005-003" could not be verified and expanded correctly.
Make sure you have permission to write to /tmp/501/TemporaryItems/com.apple.SoftwareUpdate, then try again."
