Apple OS X Root Privilege Vulnerability

•July 6, 2008 • Leave a Comment

If you are a Mac user, and haven’t seen the latest security vulnerability for OS X yet, Macshadows has an excellent writeup, with a temporary solution.  Essentially, you need to open a terminal window and paste the following command:

sudo chmod u-s /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/MacOS/ARDAgent

After you press return, you will be prompted for your password.  This command changes the executable permissions.  It will also revert back to the vulnerable permissions if you repair disk permissions.  Apple’s latest security patch did NOT correct this issue.

Portable and Cross-platform Personal Password Manager

•June 27, 2008 • Leave a Comment

Having to change between two different platforms (Windows and OS X), I wanted a functional password manager that was both portable and cross-platform.  KeePass fits this requirement, and even has a Linux port and several other versions, as well.  KeePass is open source and free.  Download the portable apps version of KeePass here, and the OS X version, KeePassX, here.  I installed the portable apps version to my thumbdrive, then downloaded the OS X version and just copied the .app file to the same directory. Make sure you keep the password database in the same directory.

MacBook Pro Hard Drive Replacement

•May 24, 2008 • Leave a Comment

I upgraded the hard drive in my MacBook Pro today. It went pretty well, but is not really for the easily technological-intimidated! I followed (for the most part) the guide at ifixit. I ran into a few things that their guide didn’t include, so I thought I would add my experience here. First, as you remove the screws, make a list of the location of the screws, and how many you removed. Be sure that you place each set in their own location. The guide doesn’t state that there are different lengths of screws. Continue reading ‘MacBook Pro Hard Drive Replacement’

MacBook and MacBook Pro USB Ports

•May 14, 2008 • 1 Comment

This week on MacBreak Weekly ( Episode 88 ) one of the hosts was having sound problems with a USB headset. They discussed the problem and one of the other hosts suggested changing the port the headset is on. A short discussion followed and here are the results. The MacBook has two USB ports on the left. The port that is closest to the screen sits on an internal USB hub with the other devices on the system (i.e. the camera). The other port is on its own. For the MacBook Pro, there are two plugs: one each on the left and the right. The port on the left is on its own. The port on the right is on a hub with the other USB devices on the laptop. You will get better sound and probably better performance out of other devices by plugging the devices into the single port.
