Use new Airport Utility version 5.6 instead. It works with BOTH g and n Airport devices. But note that version 6.0 ONLY works with Mac OS X 10.7 Lion.

Pros: If you like minimized iOS style apps, here you go!

Cons: Despite the simplification and minimization of settings and services in v6.0, there is no Setup Assistant and it a lot of users are finding it to be confusing as well as frustrating. I personally have no use for version 6.0 and use version 5.6 instead.

Summary: Apple released Airport Utility versions 5.6 and 6.0 at the same time along side Firmware Update 7.6.1 for n Wi-Fi type Airport devices. They also released accompanying documentation that has confused A LOT of people as to what is what and for what. Several of us up at Apple's discussion boards have worked to sort out the actual situation. Here is a quick summary of what we found:

1) No one requires Airport Utility version 6.0. You can entirely skip it if you don't like it. There is nothing special about it apart from it being based upon the interface for the iOS version of Airport Utility.

2) Airport Utility v5.6 is completely functional with BOTH g AND n Airport devices. This is the version to use if you want to keep full functionality control on BOTH types of Airport devices. It's that simple. You don't require version 6.0 for anything at all, but you can use it if you like it.

3) You can install BOTH versions 6.0 and 5.6 on your Mac. They don't overwrite each other. They work fine together.

4) Despite Apple's odd documentation, you CAN install Firmware Update 7.6.1 from Airport Utility version 5.6 or even earlier.

5) Airport Utility v6.0 brings with it newly updated Apple Help. Sadly, the Help has some errors and does not reconcile the differences between v6.0 and v5.6. The result is user confusion. Not good.

IOW: Just download and install Airport Utility version 5.6 and nothing changes except the added iCloud functionality and bug fix in Firmware Update 7.6.1. I personally have no use for version 6.0 and won't be using it at all.

VERY POOR SHOW APPLE. This is how to update and document things the WRONG WAY. But thank you for Airport Utility version 5.6, the REAL update, as well as Firmware Update v7.6.1 ! ! ! Both get 5 stars from me.

*This review is for version 8 (not 7.2) of the DivX installation*

I no longer recommend installing DivX and its associated files. I won't miss it.

I have uninstalled all of DivX due to the aftermath of installing version 8. I found that:

1) Google Chrome had been installed onto my Mac without any listing in the DivX ReadMe, without any warning and without my permission. I was forced to uninstall Google Chrome, which I refuse to use due to its user surveillance. Instead I use one of the Chromium alternatives that have no surveillance.

2) The DivX Preference Pane remains 32-Bit, resulting in the user having to restart System Preferences in 32-Bit mode. At this point in time that is annoying, archaic and demonstrates lazy programming.

I never liked the DivX Player in any case, never used it, and won't miss it. I also rarely run into DivX video any longer. I see no advantage in the format and no longer care about it, especially after discovering the aftermath items listed above.

It might be useful to hang onto the DivX Decoder QuickTime component if you are concerned that you may run into DivX video files in the future. I have kept it in my /Library/QuickTime/ folder. Don't bother with the DivX Encoder component.

Otherwise, good riddance DivX. I don't deal with customer disrespect and abuse.

As has been posted previously, here is the easy and OS friendly way to clear up free RAM and VM space in Mac OS X:

1) Open a Terminal window.
2) Type on the command line:
purge
... where means hit the Return key.
3) When the purge process is finished, close the Terminal app.

You're done.

If you'd like to learn more about purge, at the command line type:
man purge

For my ease-of-use, I created an automator script to run purge for me then close Terminal. I then set up a keystroke to activate it. (Add it in System Preferences:Keyboard:Keyboard Shorcuts).

Skype versions 5.0.0 - 5.1.0.922 have been found to contain a DANGEROUS security hole that allows someone with whom you are chatting to send you a message that ZOMBIES/PWNs/TAKES OVER your Mac. DO NOT USE!

Skype version 4 is NOT affected. Use version 4 while waiting for the patch.
