Appearing alongside the Mac OS X 10.6.1 update, Apple released another update today: Security Update 2009-004 is out for users of Leopard and Tiger. This update patches several vulnerabilities, including the security issue with Flash that was also part of Mac OS 10.6.1.

It's available now through Software Update and is applicable for Mac OS X Leopard, Tiger (PPC and Intel) and Tiger Server (PPC and Universal).

Walt Mossberg has answered a Snow Leopard upgrade question that has been on just about everyone's mind.

Do you need the full $169 box set if you are upgrading from Tiger? The answer is apparently no, not exactly, although that is what's required by Apple's EULA. You will be able to install the $29 individual upgrade or $49 family upgrade on any Intel Mac regardless of whether it's already running Leopard. According to Uncle Walt, as posted on the All Things Digital site:

"Apple concedes that the $29 Snow Leopard upgrade will work properly on these Tiger-equipped Macs, so you can save the extra $140."

What's not 100% clear from this report is whether the Snow Leopard install would work as an upgrade, or only as a clean install (on a newly formatted drive), as Lifehacker suggests. Since some experienced Mac users prefer to do a clean install with every major OS upgrade -- either reinstalling apps and files from backup, or using Migration Assistant to pull over from the old configuration -- this may not be a drawback for everyone. Wired's preview of Snow Leopard (based on a pre-release version of the OS) suggests that they were able to do an upgrade install from 10.4 straight to 10.6 using the conventional SL disc, but your mileage may vary.

So there you have it. If you have Leopard running on your Intel machine, you will be fine with the $29 single or $49 family versions on sale Friday morning. If you're willing to wipe down your Tiger install and start fresh, the $29 installer will probably work for you too -- but you'll be in violation of Apple's licensing agreement, making you an OS pirate. Just so you know.

Amidst the Safari and AirPort updates yesterday, Apple has released yet another update today, Security Update 2009-004. This update patches a single vulnerability affecting the BIND DNS server. It's available now through Software Update or Apple's support downloads page, and is available to download for Mac OS X Leopard, Tiger (PPC and Intel) and Tiger Server (PPC and Universal).

Amidst the release of Mac OS X 10.5.8 for Leopard users, Apple has also released Security Update 2009-003 for users of Mac OS X 10.4 Tiger. This update fixes 7 of the same security vulnerabilities that were patched as part of the 10.5.8 update. There are updates available for PowerPC and Intel versions of Tiger, in addition to PowerPC and Universal editions of Tiger Server.

These updates range in size from 76MB to 204MB, and can be downloaded from Apple's support downloads page.

The updates keep coming from Apple today. Security Update 2009-002 for Tiger is now available, both Intel and PPC. According to Apple, this update "...is recommended for all users and improves the security of Mac OS X. Previous security updates have been incorporated into this security update." It's nice to know what's being installed on your Mac, isn't it?

The Intel download is 165MB while the PPC version is just 75MB. As usual, if you notice anything especially good or bad after installing this update, please let us know.

Mac OS X has been pretty much a dream for me. I can't ever remember getting the Apple blue or gray screen of death. My Mac Pro is up 24/7 and only reboots when I've done a software update. Most of the time it happily chugs along. The same is true for my MacBook Pro. It's been problem-free except for one bad battery that started to swell. Apple eagerly replaced it.

That makes it all the more vexing when minor things go wrong that seem pretty unexplainable. One little problem is Apple Mail notification sounds. They seem to work about half the time. I have 3 email accounts, and the one that is the most unreliable is the MobileMe account. Even though mail sounds are turned on, I usually don't get any sound when mails comes in. I use the 'glass' sound, but it fails on any selection. My POP mail accounts seem to trigger the alert properly.

This same problem existed in Tiger, and has survived several Leopard updates. This minor but irritating issue exists on both my computers, and so far has eluded all my detective work to eliminate it. This bug is impervious to permission resetting, changing default mail sounds, playing with the sound control panel, (yes, 'play user interface sounds' is checked) and making sure that Growl and other 3rd party hacks are nowhere on my computers. The guys at the Genius Bar scratch their heads and smile.

The Apple support boards are full of similar complaints, and when you eliminate the people that had their sound turned down, or the other obvious fixes, there is a pretty large residue of people who have this problem. Apple must be aware of it.

Don't get me started on the error I get 2-3 times a week when Time Machine tells me a backup didn't work, and then the next hour everything is fine. This is another error that has survived several Leopard updates. Like a good citizen, I always do the larger combo updates to have the best chance of replacing any bad system components.

Every OS has a long list of issues. Actually, I find the current build of OS X the most reliable system software I have ever used. That said, I'd love to see some of these little bugs cleaned up. I'm sure you have your own lists and will share them.

Maybe Apple will read this and send me a fix for my notification sounds issue. The problem is, I probably won't notice the mail when it comes in. Grrrrr.

Apple released Security Update 2008-007 for Mac OS X Leopard and Tiger users today. The update addresses many specific areas of the Mac OS, including: Apache, ClamAV, CUPS, Finder, and more. A full list of the areas affected by the update can be found on the Apple support website. The update is available for the following systems:

• Client systems running Leopard
• Server systems running Leopard
• Client systems running Mac OS X 10.4.11 (Intel)
• Client systems running Mac OS X 10.4.11 (PPC)
• Server systems running Mac OS X 10.4.11 (PPC)
• Server systems running Mac OS X 10.4.11 (Universal)

You can get the update by downloading the installer package from the Apple support website, or by opening Software Update (Apple menu > Software Update).

If you've been a bad nervous Mac user, then chances are that you might not be running the latest updates. If so, you can download the Combo updater for Mac OS X 10.5.5 which includes all important patches up to this point, so you can remain up-to-date even if you skipped a couple of updates.

If you are still running the slightly older OS, Tiger, then Apple has provided an update for you as well. The Security 2008-006 update allows you to stay as safe as your Leopard brethren. Security update 2008-006 is available for both PPC and Intel Macs running Mac OS X 10.4 (Tiger).

You can download all of these updates by opening Software Update (Apple menu > Software Update) or by visiting Apple's download page.

When Apple made the move from Tiger to Leopard, they decided to throw in more than a few features. One of those new features was the ability to search Wikipedia right from Dictionary.

To start searching Wikipedia, just open Dictionary (located in /Applications). Next, click on the Wikipedia button and enter a search term. Leopard will then browse Wikipedia for the answer.

You can access the dictionary from most applications by highlighting a word, right-clicking and selecting "Look Up in Dictionary."

By now, everyone knows about the awesome power/productivity achieved by using Exposé. Well, here is one time saver that Apple built into OS X which you might not have known about.

After you invoke Exposé by using either the Exposé key, F9, or F10, pressing the tab key will cycle through your open windows, one application at a time (all the Safari windows, then all the Mail windows, then... etc.). Keep pressing the tab key until you reach the application that you are looking for.

If you want to return to the previous application while Exposé is still activated, just press shift + tab. You can select a specific open window in the app by clicking with the mouse or using the left/right arrow keys.

Apple has just released a new security update for client and server users of Mac OS X 10.4 (Tiger) and 10.5 (Leopard). This Security update 2008-005 is "recommended for all users and improves the security of Mac OS X," and includes fixes for a dozen or so features in Mac OS X.

This update fixes a QuickLook bug where loading a malicious Microsoft Office file could lead to "arbitrary code execution." Doesn't sound too good to me! It also fixes a DNS vulnerability that has been highly discussed over the past week (and which many other vendors have already patched).

You can download this update by opening Software Update (Apple menu > Software Update). You can also find more information on what this update fixes by looking at Apple's support note.

Today Apple released an AirPort Extreme Update for those Mac users running Mac OS X Tiger (version 10.4). Here's the information that Software Update gives us:

This update is recommended for all Intel-based Macintosh computers running Tiger OS and improves the reliability of AirPort connections.

You can get this update by either opening Software Update (Apple menu > Software Update) or by downloading the installer package from the Apple Support downloads site.

Just in case you haven't yet upgraded to Leopard, but still love using Cocktail (that crazy mix of Unix functions for OS X), Maintain has released version 4.0.1 of their Tiger edition. They've fixed some compatibility problems with QuickTime, and added support for clearing font caches in Microsoft Office 2008. The update is now available from their website, and is, they say, "strongly recommended" for all Cocktail (Tiger edition) users.

Cocktail's Leopard edition is at version 4.0.2-- that update fixed these same problems last week, as well as fixing a network optimization bug for DSL (PPPoE) users.

I used the original Boot Camp beta last year just to see it work. I applied the subsequent updates, but haven't tinkered with it since.

Today, I received an email from Apple that reads, in part:

"...With the introduction of Leopard, the Boot Camp Beta program has ended. The Boot Camp Beta software will expire on December 31, and Apple won't offer further updates of Boot Camp Beta for Mac OS X Tiger."

There's your warning, Tiger users. The Boot Camp beta expires December 31st. Upgrade to Leopard or run unsupported. You don't want that, of course. Windows needs all the support it can get.

Thanks to everyone who sent this in.
