Sure enough: networksetup -setairportnetwork Airport 'Your SSID Here' 'Network Pa$$wOrd Here' did just what I wanted, and it did not require an administrator password or sudo. If you need to get a listing of all of the current Wi-Fi networks which are broadcasting SSIDs, you can use 'airport -s' for a list which will also show what security measures are used. By the way, if you aren't familiar with networksetup, you should definitely read up on it. It has a lot of features that could come in handy. It also wields a great amount of power, so be careful. The command listed above is fairly innocuous but there is a lot more it can do.

Bugs & Fixes: A potentially risky Finder permissions command | Mac OS X | Mac 911 | Mac... - 0 views
-
In brief, enter sudo chmod -RN ~ in Terminal, followed by starting up from an Install DVD and selecting “Reset Home Directory Permissions and ACLs” from the Rest Password utility.
-
Suppose you want to change the permissions settings of most or all the items in a given folder. Perhaps you want to modify permissions so you can access the content of files you would normally be prevented from editing. Or perhaps the permissions of your own files have somehow gotten messed up so that you can no longer copy or move them.

How to Switch to the Mac - Tao of Mac | February 2007 | Rui Carno - 0 views
-
the installer creates the first user account. This is the important bit: it is an administration account – call it “Administrator” or something like that and create another for yourself afterwards (if you’re a UNIX head, this is not root, which is disabled).
-
Q: Why doesn't the installer _tell_ you this? It looks and feels like an ordinary unix user with 'sudo' access, but according to Tao, it can be troublesome. A: My guess is that Apple doesn't want you to have to remember two passwords. Perhaps Apple decided, unlike Tao, that the security of asking for passwords for important tasks is good enough.

XBinary Extended Binary Format kernel binary Universal Binary format Apple Inc. Mac OS X

—With the advent of x86-based Macintosh computers, Universal binaries, originally known as "fat" or multiple-architecture binaries, appeared in Mac OS X.
-
a "4-way fat" executable could consist of Mach-O executables for the i386 (32-bit Intel), x86_64 (64-bit Intel), ppc (32-bit PowerPC), and ppc64 (64-bit PowerPC) architectures
-
Mac OS X does not provide any kernel-level or user-level interfaces to extend binary format support.
-
Let us call the new software that implements these features XBinary. binfmt_misc Those familiar with the Linux kernel will realize that functionality similar to what's been described here exists in Linux as the binfmt_misc kernel feature. XBinary is conceptually similar

XBinary: extended binary format support for Mac OS X Copyright (c) 2009 Amit Singh. All Rights Reserved. http://osxbook.com The XBinary software allows you to extend the Mac OS X kernel such that it can recognize arbitrary binary formats and execute them through specified handler programs. (Mac OS X natively supports executing only Mach-O binaries, Universal (fat) binaries, and interpreter scripts.) XBinary consists of a kernel extension (xbinary.kext) and this command-line tool, which lets you control the XBinary facility. This requires superuser privileges, so you should run this tool using sudo(8). The XBinary kext must be loaded for the facility to be available.
-
You can also specify flags that affect how a matched entry is processed. By default, the argument vector IS adjusted and setuid/setgid binaries are NOT allowed.

We don't even have to write such scripts

Executive Summary This document discusses XBinary, a new software that lets you add kernel-level support for executing files in arbitrary binary formats on Mac OS X.
-
Each entry must have as its name a unique identifier string up to 31 bytes in size. Additionally, a set of other arguments specify to the kernel how to recognize that binary format and which interpreter to invoke to handle it. XBinary can recognize a binary EITHER by matching magic bytes within the first page of the file OR by matching a file extension. OTHER_ARGS must be a valid combination of the following arguments (some are optional).
