Hi Dave. I have a question that I don't think you've ever written about: I have a folder with confidential information and want to encrypt or password protect it. I can see how to create a ZIP file from it with the Archive feature, but that's not password protected either. Is there any way to accomplish this in Mac OS X Snow Leopard?

I feel like a total chump: a few months ago I changed all my system passwords to ensure my girlfriend didn't mess with things (we were fighting a lot, we're no longer seeing each other). Not a problem on my iMac or Mac Mini, but on my MacBook Air that I promptly slipped into the closet anyway? I have no idea what the password is and can't log in to use it any more! How do I reset my account password in Mac OS X Snow Leopard on my MacBook Air??

I thought I had turned off the "guest" account on Leopard, but was then darn surprised when a friend showed me that when he looked at the Network in our office my computer showed up. Worse, he could poke around on my file system as Guest!

I'm running Mac OS X Leopard and the transparent menu bar is slowly but surely driving me batty. Isn't there some way to make it opaque and white again? Man, it's darn hard to read much of the time!

I've been getting into trouble lately for not seeing email that my husband's sending me. I don't get a huge amount of email, but when a wave comes in, his mail does, well, get lost in the shuffle. Is there some way I can change the color of his messages in Microsoft Entourage on Mac OS X so that it stands out more?

I'm migrating from an old Mac computer to a shiny new MacBook Pro and want to be able to join my brother's network, except we don't remember the password! But my old computer can connect. Is there any way to dredge up that password from Mac OS X so I can enter it anew? I do have Leopard running on both systems...

I'm loving Mac OS X 10.5, aka Leopard, but there's one "feature" that's driving me crazy: when I print anything, the printer application hangs around until I quit it. In the good old days (Panther) the printer would quit and vanish once the queue was empty. Is there some way to restore that behavior?

I just upgraded my G5 mac to the latest Leopard software and am leery about syncing my iPhone with my computer because I'm afraid I'll lose data. However, I really need to get the photos off the phone and don't want to email them to myself, one by one. Your suggestion?

Somewhat inadvertantly, I have been thrust into the world of the latest Mac OS X system, Leopard. Some months ago, I bought a top-of-the-line Apple MacBook Pro from my friend and colleague Jeff Walker (thanks Jeff!) and have subsequently had a variety of hardware problems with the unit. The first problem was the power switch, which ended up slightly akilter inside the unit and would stick. Not good. But quickly fixed.

This time, however, the power switch went a bit wonky again and the latch switch also became sticky. To top it off, a few keys on my two month old keyboard were already losing their letters / details, so when I took the unit in this time, I asked them to fix everything. They did. I have a new keyboard, new lower chassis, new power switch assembly and, yes, a new latch switch. Very cool.

Unfortunately the Apple techs went above and beyond and did one more thing while they had my laptop, something that caused me to lose 130GB of data...

Can you offer up a better explanation of the new Time Machine capability that Apple has unveiled for its upcoming Mac OS X 10.5 operating system? I've read that it's some sort of automatically backup system, but don't see how that can work without massive reengineering of the entire Mac OS?
