No worries. I would do it, but it's not a necessity. : )

I doubt it. But like I said, it won't be a huge issue either way.

But that's the old ugly desktop box which was mostly empty space inside
... now you've got a good looking all-in-one computer that is crammed
full of bits and pieces.

These days almost none of Apple's devices are user-accessible at all.
The vast majority of users have never wanted or been able to fiddle
about inside their computer anyway - they'll either pay a tech repair
centre to do it or simply buy an newer device. 

The 27" iMac does still has the trap door to let the user change / add
RAM. The cylindrical Mac Pro can be easily opened, but apart from
adding RAM or perhaps swapping the SSD, there's not really anything
else you can do inside that anyway since it can't take standard
graphics cards, etc.

Everything else is fully sealed, often requiring specialised tools and
other equipment for those few who do want to muck about inside their
computer.

Those were the days of the old IBM corporate look!  All those MCA bus 
cards, daughter cards, massive hard drives, etc.  Man, those things were 
made from heavy gauge steel and were heavy!  I had a Model 60 tower that 
weighed over 80lbs!

Have all Mac users been like that, not wanting to fiddle/upgrade cards, 
etc.?  That is how I grew up in computers, taking them apart, upgrading 
CPUs, video cards, network cards, hdd, floppies, etc.  I just thought 
that everyone did the same thing!

I'm still using a beige PowerMac G3 Minitower which, like all Mac
minitowers since then, is very easy to get into (although finding any
upgrades for it can be difficult these days) ... just push the button
on the top down and the entire side of the case comes off, and the top
layer (when on it's side) containing the drive bays is hinged so it can
easily be lifted up to gain access to the motherboard, card slots, etc.

It's not just Mac users ... it's the vast majority of computer users,
no matter whether they are Mac or Windoze users. Most people simply
aren't interested in mucking about inside the computer. They just want
a tool that works. It's the same with a car - most people are not
interested in mucking around in the engine bay and leave that to a
professional mechanic.

The original compact Macs were not user-accessible (partly because the
in-built display could mean a nasty electric shock for anyone not
knowing what they were doing. Some of  the later models which had
separate displays, like the Mac LC series, were easily opened up by
those who wanted to (the LC series is a lot like the old Apple II,
which was also easy to open up and plug stuff into).

I like to dig in and upgrade and fix things.  Indeed in my PC days a 
given PC "box" would see several card additions/changes, memory and hard 
disk changes and in the last box, two motherboard changes.

My last iMac had a failing hard disk and Apple (Montreal) wanted "5 to 
10 business days" to replace it.  So I did it myself.  It's not a big 
deal especially with the iFixit guides to prepare you for it.

And it's not true that the latest are not servicable.  They're just less 
and less "normal".  On my current iMac I would need a guitar pick to 
separate the glue holding the screen to the iMac and then a replacement 
kit from iFixit for that glue (a "glue gasket").  And I'd have to remove 
even more stuff just to get at the hard disk.

That sounds scary, removing the glass screen!  Almost like removing the 
screen from a laptop and then removing the glass from that screen.  I 
have only taken apart one laptop to upgrade a hdd, that is my old Packard-
Bell which my daughter took to college with her.  It is still with me, 
running DOS/W3.11, with a 250meg hdd, and 12 megs of ram!  It was a real

Sure, but today computers and devices are miniaturized to a larger
extent, which means assembly (and therefore disassembly) will be more
complicated. And in many ways, Apple leads that charge. Such is life.

Certainly not. Your Name's blanket statement does not apply to all Mac
users equally. Many of us are very technical and skilled with lots of
experience taking things apart and repairing them.

Many of us have. Back in the late 90s and early 2000s, most of the
computers in my home were hand-built PCs running various flavors of
Linux and Unix. Today, I have no PCs in my house. All of my machines are
Macs. And while I make my living working with Linux and Unix servers, I
don't bother running Linux at home, because OS X does all I need. And I
repair all of my Macs that are out of warranty myself rather than
bringing them some place. For instance, I recently replaced the cooling
fan on my ATI Radeon HD 4870 in my Mac Pro tower because the bearings
were failing. Total cost: $6.99 for the replacement fan, and 20 minutes
of work. : )

Yeah, have replaced a lot of those fans, both on CPUs and on video 
cards.  The CPU ones were "glued" on the CPU, just had to have the right 
technique, I used a small hair dryer, to get it off, then cleaned it, 
then applied more heat paste and then, ready to go.  The fans were a lot 
cheaper than buying a new video card.
Since I let my IBM machines go, except for the PS/2, I have not futzed 
around inside a case.  I got rid of all my cards and various crap when I 
moved from FL to TX(now I wish that I had some of that stuff back!).
Besides my two Thinkpad T400s running SL 6.6, I have three more old 
laptops, one an old PB running DOS/W3.11 that was my daughter's in 
college.
Another old hand-built AMD K2 machine going to run OS/2 Warp 4, and my 
late father's old Dell SX620 running XP SP3 that I am using with DOSBOX 
to run a crap load of old games!
The new iMac will start off with all the iTunes/iPhotos from the old G4, 
and then will go from there.

Yep. The fan on the Radeon HD 4870 is attached to a heat sink with
thermal paste between the heat sink and the GPU. Replacing it requires
you to remove the heat sink and thermal paste and replace it with new
thermal paste (and the new fan). The RAM chips are cooled with thermal
pads connected to the card chassis rather than thermal grease to the
heat sink. Here's what the poor thing looked like when I first took it
apart:

<http://tinypic.com/view.php?pic=m3epi&s=8>

You can see that the thermal paste had hardened up a bit, and probably
wasn't doing as good of a job transferring heat from the silicon to the
sink. I bought this Mac Pro back in 2008, and while I do give the
computer a good dusting once or twice a year, I had never taken the
graphics card apart in all that time. So the dust buildup inside of the
graphics card was substantial. Needless to say it runs a lot cooler and
a lot quieter now that I've given it a good cleaning, new thermal paste,
and a new fan. : )

A question as to Apple video cards.  Why are they so expensive?  They are 
the same as the regular PC card, so what makes the price difference?  I 
have read something about them needing to be "flashed" like a BIOS?
As Seinfeld would say, "What's the deal?"

The "teardown" is overkill for cleaning it out.  Following the disk 
replacement sequence (or less) is enough to get the vacuum and wipes in 
there.

OS X is not a walled garden.  More of a courtyard on the highest hill in 
the realm.

Easy to defend yet allows for all sorts of apps, one can roll ones own 
(as I do) and has security features with a lot of flexibility.

With Yosemite, you need to disable the walled garden with NVRAM settings
to install kernel extensions. So while it is *still* possible to disable
the walled garden, Apple is making it harder and harder.  This isn't
something you can disable in the GUI.

It is not known if Apple will stop tightening things at the current
level or further tighten the restrictions to possibly eventually arrive
at a fully enforced walled garden. Apple knows, I don't.

How do you do this?  Does Apple have kernel extensions like my Linux has? 
Are there newer kernels that you can download like Linux?

it does, but not like linux.

some apps may install kexts, however, they now need to be codesigned so
that malicious ones can't do anything.

disabling codesigning is stupid.

You don't need to, and shouldn't, because it skirts security.

> Does Apple have kernel extensions like my Linux has? 

They aren't the same, of course, but yes. It's not like you can install
a Linux kernel extension in OS X. ; )

Have a look in the /System/Library/Extensions and /Library/Extensions
folders some time.

> Are there newer kernels that you can download like Linux?

Apple system updates include kernel updates.

There are plenty of kernel *extensions* on OS-X. But starting with
Yosemite, they must be signed (which means Apple approved and
transmitted via Apple App Store).

This does not mean changing the kernel, it just means an extension to it
(think of it as a low level driver like a disk drive driver).

Some software will patch an Apple provided kernel extension, which
obviously will invalidate the signing check unless you disable that check.

nope.

a developer can codesign their own kexts, just as they can codesign
their own apps.
