It strikes me as being bad form to let users have physical access to
their computers and even worse form to allow them permissions to
install anything on them. Bring back the mainframe I say.


Many software publishers would like to see that happen. Except, what you
call mainframe, they call the cloud.

Bring back dumb terminals.

iPads?


There is a distinction between terminals, and users. ;-p

There's a joke in that... Whatever, webservices and terminals are
basically the thing.


I was not being at all serious.

"The amusing vulnerability in Apple's OS X that grants
administrator-level access to anyone who asks is being exploited in
the wild by malware. Yeah, malware exists for Macs, this isn't the
1990s.

Anyone logged in to a vulnerable OS X computer, or any software
running on it, can use the security hole to gain the same privileges
as the powerful root user, meaning they can install new programs,
change files, remove or add new users, wreck the system, and so on, at
will.

According to Adam Thomas of Malwarebytes, dodgy software distributed
on the internet is now exploiting the vulnerability to inject the
VSearch and Genieo adware plus the MacKeeper junkware on to Macs, and
point users at an app to download from the official App Store."

I just went through an update session of my w8 laptop... 107
patches... Whatever, I feel blindfolded on Windows in comparison
with the OSX or Android operating systems.

With El Capitan, no matter how elevated your privileges, you
can not edit, add or remove files in the locations /System,
/bin, /sbin, or /usr (except /usr/local).

Only Installer and Software Update can do that, and only using
Apple-signed developer packages.

There is no "real root".

sid:
The real root user is the one that signs the packages if they
are the only things that can write anywhere.

Sandman:
No, as I said - there is no "real root". The system is built so
that no user privileges, including root, can write files to
specific locations unless they are being installed using a
specific application using a signed certificate.

Which is just what I have been saying. Even if you log on as root
you can't actually write everywhere, ergo you are not really root.


And this is where we have corrected you - you ARE "really" root. There is
no other root that the root account.

You're basically saying that if tomorrow the president lost his power to
launch missiles, he's not "really" president.


Well if you stretch the missiles bit to 'any important decisions' then yes,
who ever actually makes those decisions is really in charge, regardless of
the name you give to either.

And to be clear I am using the term root as it would traditionally
be used not how it is being misused in the upcoming OSX


There is no "misuse" or "traditional" use.


http://www.linfo.org/root.html

"root Definition"

"root is the user name or account that by default has access to all commands
and files on a Linux or other Unix-like operating system. It is also
referred to as the root account, root user and the superuser.

Root privileges are the powers that the root account has on the system. The
root account is the most privileged on the system and has absolute power
over it (i.e., complete access to all files and commands). Among root's
powers are the ability to modify the system in any way desired and to grant
and revoke access permissions (i.e., the ability to read, modify and execute
specific files and directories) for other users, including any of those that
are by default reserved for root."

sid:
Being "rooted" doesn't mean only access to a users home
directory has been achieved does it?

Sandman:
Indeed, and in El Capitan, these locations can't be "rooted".

I'm unsure whether you don't know how the root account works in
unix

I do.


As I said, I'm not so sure, given what you've said thus far.

Sandman:
or if you don't know how OSX works right now.

Which bit in particular?


Are you asking me what parts of OSX you are ignorant about?


No.

Well..? It seems that Apple is going the SELinux way by defacto
replace Roots superuser privileges with those of an
administrator... No, I don't like it either!
Now: Guess who the original sponsor for SEL was?;-p
