No, sorry: it isn't :-) Not in here, where we have to be careful to call
things by their correct names or we end up confusing folks.

An "update" is computer software manufacturers trying to avoid using the
term "Bug Fix" because they love to pretend that their software doesn't have
any bugs. Sad, really...

But an update contains only changes to enable the software to achieve its
design more reliably.

An "Upgrade" contains code that adds new features to the software. It's a
new version.

to me a file when downloaded reach 30, 40 or up Megabyte is is an
upgrade (whether paid or or not)

Size has nothing to do with it. I know that as a man, you will have
difficulty with this concept. But it doesn't :-)

an up date is where if you download by
automatic update reads the contents of of the update, reads the contents
of the applications and support files to be updated and only replaces
the exact items actually changed.

You are talking about two different methods of applying updates. You are
describing the "Delta" method, which replaces only the changed parts of a
file. The last major software manufacture I saw doing that was Corel
Corporation.

These days, I believe ALL software houses update by "file replacement",
where they replace entire files with new ones. More than anything, this has
to do with the way object-oriented programming functions. Because of the
way the executable is laid out, if you change some part of it, you have to
change all of the other references to it, which usually means replacing the
whole file. Modern security practice causes developers to "randomise" the
layout of their code, to make it more difficult for the bad guys to figure
out where the credit card numbers and passwords are. You can't "delta" an
obfuscated file, because you don't know where the pieces landed either :-)

My apologies, I was un aware That MS Emulated Apple in the use of Combo
Updater and could actually skip previous updates. Glad they have come
into the modern world :-)

Yeah, well Phillip you are about 20 years out of date on the Windows side of
things. Really you shouldn't comment until you have had a look! Microsoft
has been issuing "Service Packs" as long as I can remember. The update from
DOS 5 to DOS 5.5 was the first one I remember: it was what you call a
"Combo" update.

Microsoft has been doing this as long as Apple, if not longer.
At least that will be better than, than Adobe's method where you have to
run all previous updates in exact order, even if only 500 bytes of code
are changed. :-(

Microsoft still does that too. I wish both companies would clearly and
accurately indicate when they are doing this. It would save administrators
a hell of a lot of time.
Apple's numbering system for OS version are unique for OSX.

OSX.1, OSX.2, OSX.3 , OSX.4, OSX.5 can't even be considered Upgrades as
such. They are totally different animals (pun intended)or completely new
systems. Often they use totally different version of the Mach Kernel,
The UNIX is totally different. In fact from X.2 to X.3 they went from
the use of BSD UNIX which they had to paying a licensing fee to Berkley
(Royalty Fee) for each copy sold, to FreeBSD. which is under the GNU
type Licensing system. And is actually totally different write up from
BSD. has many more and richer command sets than BSD. I don't have OSX.5
I don't have anything fast enough to install it on. So I have no idea
what type UNIX is used. who knows might even be X86 or XFree86 since
Intel chips are now used.

I think it is worth recognising that the "X" in OS X is really not part of
the "version number". It's just a marketing name. If you accept that, then
we have Apple Unix Version 1, 2, 3, 4, 5... And things become a lot easier
to understand.

I am using Apple Unix 4.11 here. Some people are using 5.3.

Cheers

Well they are a little behind its my understanding that 5.4 is out now.

and in my case I am stuck with OS 3.9 on the main drive on my G4-500 and 4.11 on my laptop

as for updating On a update from software update on my Macs' and on any updates ?upgrades such as 12.11

I get the same basic messages.

checking computer for file to replace,
checking package contents ,
verify files, setting files for installer to change
creating installer script.

Install files.

Optimize system.

ON MS installer similar to above except

looking for files to change

then you see a running count and the titles of the files passed by then pauses and message shows replacing file xyz then continues to run with a series on names running fast pause, replacing ZDA and so on then at end optimize, then finished install.

in all the install for office it actually tells you exactly which files its replacing. It doesn't give the warning about the optimization. but the pizza wheel runs and the progress bar continue until finish. The setting of prebindings is what links all components to each other.

Next time I have to do an update I'll use SnapzPro to make a movie so you can see what it does. and I'll send to you.
