I’ve mostly been very happy with my migration to Lion, but I did get bit with one bug after the upgrade: for the life of me, I couldn’t get sound to output through HDMI when using my Kanex Mini DisplayPort to HDMI Adapter. That meant the days of hooking my 11-inch MacBook Air to my 47-inch 1080p HDTV were at an end.

I wasn’t alone. Apple’s support communities are filled with threads from frustrated Lion upgraders who suddenly lost the ability to pump sound through their HTPCs. HDMI sound also stopped working on my girlfriend’s MacBook when she upgraded to Lion. It’s obviously a widespread problem.

Luckily, today I finally figured out how to fix the issue, and it was remarkably simple. Here’s how to get HDMI sound back into Lion.

If you’re still banking on Apple releasing the iPad 3 this October, this might disappoint you: there’s just no chance that an A6 SoC will be ready this year. In fact, if there’s going to be a quad-core chip at the heart of the iPad 3 at all, we might be looking at an iPhone 5 sized delay between tablet generations by the time the next iPad comes around.

Apple provided some great default keyboard shortcuts in Mac OS X Snow Leopard and one of my favorites was Command+D. You could use that keyboard shortcut combination to select the Don’t Save option when closing a document you haven’t saved yet. Unfortunately Apple decided to change the keyboard shortcut combination in Mac OS X Lion.

One of Lion’s most impressive features is the new way that the OS handles the saving and managing of files. Versions and Resume allow the user to never have to worry about saving or losing files again — Lion just takes care of it.

If you still don’t really understand how Lion saves files, check out this infographic to see the process laid out in a simple way.

Having gotten used to carrying a task management app in my pocket for some time now, I’d struggle to get through the day without my trusty to-do list. But for a group of amnesia patients in Ontario, Canada, apps are doing a lot more than just reminding them to buy milk. They use Apple’s iPod touch as a “memory substitute.”

Hey, good news! If you’re one of the many people having problems installing Lion on a clean machine, Lion USB media is now shipping!

Samsung has just announced the successor to its PM810 solid-state drive which is a super-speedy 6Gbps SATA 3 that boasts read speeds of up to 500MB/s and write speeds of up to 350MB/s. A custom version of the PM810 is currently used in Apple’s MacBook Air line lineup, so there’s a good possibility its impressive successor — the PM830 — will also hit the ultraportables.

One of the most noticeable changes in OS X Lion is Apple’s reversal of traditional page scrolling. In Lion, Apple has adopted an iOS approach to scrolling by changing the way that the user scrolls up and down; instead of moving the window around the content, you actually move the content itself.

This method of scrolling works great when you’re on a touchscreen device like an iPhone or iPad, but a more traditional desktop experience doesn’t lend itself to what Apple calls “Natural Scrolling” in Lion.

If you’d like to go back to the old way of scrolling in Lion, here’s how to do so.

Eight years after retail giant Walmart announced its ‘iTunes-killer’ 88-cent MP3 downloads, the company is waving the white flag and closing shop later this month.

Someone must use Facebook’s chat system, because the social networking giant just released Facebook Messenger, a dedicated iOS app that allows you to send and receive messages or chat with friends on your iPhone, iPad or iPod Touch. It even comes with push notifications so you won’t miss any messages.

More interestingly, though, Facebook’s Messenger app contains files that hint at future video calling functionality to come.
