There are a couple of ways to force an app to quit, which can be useful when one is frozen, or it just decided to launch itself and you don't want it to (like iTunes does when you plug an iDevice in):

• aim for the kill: right clic on the dock icon. If it shows "Quit" instead of "Force Quit", press the Alt key and it should toggle to "Force Quit" 
• the worm in the Apple: clic on the Apple icon (top left of your screen), select "Force Quit", pick your app and press the "Force Quit" button 
• the Windows way: press "cmd + alt + esc" keys altogether, and it should prompt the "Force Quit" men

And as the little green guy would say, "May the Force Quit with you".

Until everything is in the cloud and you don’t have to take care about this anymore, getting a new computer often means that you need to move your iTunes library manually.

There are a couple tools online, most of the time they’re not as free as they claim, and really it will take you more time to learn how to use these tools than to read the official Apple way of doing it.

So the only thing you need to know really, is go to the Apple Support page and follow the steps.

Now there’s one point where you might get stuck at if you’re using Windows 7, which is step 4 of the “Restoring your iTunes Library backup” section, where they tell you to “Open iTunes while holding down the Option key (Mac) or Shift key (Windows).”

Unfortunately, this won’t work under Windows 7. What you really need to do is:

• locate your iTunes.exe file, which should be in something like C:\Program Files (x86)\iTunes\
• hold shift key
• right clic
• select Open

You should then get the “Choose iTunes Library” popup and be back on track.

Here's a simple, free, and quick way to combine single images into a unique pdf if you have Mac OSX with Automator (it's a pre-installed app, so you don't have to download any app).

There's a couple "classic" ways to do it, but most of the time you'll get a poor result if you have images with different sizes.

To get started, download this workflow:

Then, here's what you have to do:

• open the workflow file (it should load Automator automatically) 
• go where your images are stored, and select those you want to group 
• go to the Automator window 
• (optional) change the destination (default is Desktop) and change "PDF NAME" to whatever you want to name your pdf in the "New PDF from Images" box 
• press "Run" (top right corner) 

And you're done!
