SD Won't overwrite 10.8.5

[RobertJ]

I have two drives, call them A and B. I installed Mavericks on A. B has a clone of A from two weeks ago with 10.8.5.

When I try to do a Smart Update of A -> B, Get Info says after the clone that the OS is 10.8.5.

I have used this before with earlier OS's. Do I need to Wipe drive B?


EDIT: Both drives are internal to my Mac Pro.

EDIT/EDIT: A has 35G and B has 29G used.

Part of mystery solved.

Rebooted and B now says 10.9 in Get Info; however,

A has 35G used

B has 29G used

I also verified this using Disk Utility

EDIT: The Mavericks installer is about 5G. Is it possible it didn't get deleted and is still lurking on A?

EDIT/EDIT: Looked at all the directories on A & B (Applications, Library, System & Users). They are each identical in size and add up to about 29.4G. Seems there is a large hidden "something" on A of about 5G.

EDIT/EDIT/EDIT: Turned off invisibility and again looked at the directories in A & B. Found that the "private" directory on A has 3.25G whereas the "private" directory on B has 950M. That would account for about 2.3G of the 5G difference. I would assume that SD would clone all directories including "private". ???

It's caches, sleep images (which is in private), swap files, etc. Nothing to worry about.

Thanks. Little things like this drive me crazy. :confused:
