'... why Tiger 10.4.6 update download is at top of the page with the latest iPod & iTunes software download.' - all you see are pictures (of 'Mac SO X Update 10.4.6' and 'iPod + iTunes') with links to actual web pages (not the files to download) beneath them. If you clicked on 'PPC' beneath 'Mac OS X Update 10.4.6' you would be transfered to '
Mac OS X 10.4.6 for PPC'.
The above [65 MB] 10.4.6 update is only those who have MacOS X 10.4.5 installed, and wish to have 10.4.6 installed.
'If one wanted to update from 10.4.5, all they had to do is scroll down to the 3rd? page to download it.' - The actual links to download 'Mac OS X 10.4.6 for Intel', 'Mac OS X 104.6 for PPC', 'Mac OS X 10.4.6 Combo for PPC', and 'Mac OS X 10.4.6 Combo for Intel' are on the second page of downloads.
Always - use the 'Combo' update; regardless of what version of Tiger is installed. Do a search on 'Google' and within the 'macosx.com' web site, you will see many suggest this, over the incremental updates (which 'MacOS X 10.4.6 PCC', mentioned above, is).
'Is the 10.4.6 an update for an install disk?' - well yes ... and no.
Yes explained:
You can install MacOS X from the Install Disc, then you install the downloaded update (with a late number greater than that of the installation).
No explained:
You have installed Tiger (in the past), which has since been updated (to a version greater than that installed), and can then update Tiger even further (should such update exist).
