I need to go into the Apple Store to talk with them about my broken iPod [ed note: see my article how to fix your broken iPod first, perhaps it'll help?] and was told that it's far smarter to make an appointment at the "Genius Bar" than to just walk in and hope that there's space in the schedule. How do I make a genius bar appointment?

I saw a demo of a video chat using FaceTime where one person was on their MacBook and the other was on their iPhone 4. Incredible! How do I set up my Mac so I can have face to face chats with my girlfriend, even when she's on the road with her iPhone 4?

Okay, so I now know how to pair a cellphone with my Mac via Bluetooth - thank you! - but I am still unclear about how to actually transfer a file to the device. Can you shed light on this additional step, Dave?

I saw your earlier article about how to pair a bluetooth speaker with a Mac OS X system, but am wondering about how to do the same with my son's older LG phone? I know that the iPhone has a good connection with the Mac OS X system, but what about other cellphones that support bluetooth? How do you pair 'em?

My brother sent me some really cool wireless bluetooth speakers for my computer and I can't figure out how to make them work. Is there some secret to getting a MacBook to use a bluetooth speaker system?

I've taken the plunge and installed Snow Leopard (aka Mac OS X 10.6) and was pretty psyched about the fact that it's a 64-bit operating system, until my brother said "yeah, but I bet you're still running in 32-bit mode". How can I tell if my Snow Leopard computer is now running in 32-bit "compatibility" mode or as a true 64-bit operating system?

I can still remember the first Mac I used: it was a 512K unit that the fine folk at the Whole Earth 'Lectronic Link loaned me when they hired me to hack their discussion system and make it faster. At the time I'd just left my job at Hewlett-Packard and had no computer of my own (back then people didn't have computers unless they were hardware hobbyists or could handle cassette backups).

To the proffered loaner Macintosh I can recall saying "uh, no thanks, I don't really need a toy computer. I'll figure out another way to connect to your computer network." At the time, I was living in Los Altos, basically southwest of Palo Alto and due north of Apple headquarters in Cupertino, and the WELL was located north of the Golden Gate bridge in beautiful Sausalito. Way too far to drive for the work. So I had to get a computer of some sort.

I reluctantly accepted the dorky little fishbowl unit that was reminiscent of the Osborne my Dad had won in a sweepstakes a year or two earlier, and...
