This page contains features and/or settings I have found useful on the Mac.

More will be added, so check back.

• Relocate your iTunes folder
  You may wish to relocate your iTunes folder. It makes no sense to have the default location under the Music folder. iTunes downloads everything there, music, movies, iPhone apps, and more. I relocated mine under the Home folder, at the same level as Music, Documents, etc. To relocate your iTunes folder, take the following steps:
  • Quit iTunes
  • Move the iTunes folder where you want
  • Hold Option and launch iTunes
  • Select Choose library and select the iTunes folder in the location where you moved it
  • When you started iTunes, it may have created an empty iTunes folder in the old default location (done before you get a chance to make the selection). That can be safely deleted.
• Put your own image icon on a Stack
  For example, you may create a Stack called "Quick Apps" so you can see a quick fan of frequently used applications. You create a folder by that name and put in aliases for the applications you want. Create a 48x48 image file (jpg or png) with the icon you want, make sure to hide the extension (in get info). Use the name " Quick Apps" (note the leading space) for the image, and put it in the "Quick Apps" folder you will use for the Stack. Drag the folder to the right side of the Dock to create the Stack.
• Select any one of multiple "from" addresses in Mail
  In Preferences > Account Information > Email Address you can put in multiple email addresses separated by a comma. Then when you compose an email you can select the address to use in the From dropdown box.
• Use multiple address books
  You can use multiple address books by using File > Import/Export from within Address Book. This will allow you to have multiple address book archives and import the one you want to use. You can print address labels from within Address Book using File > Print > Style - Mailing Labels.
• Skip the trash for USB drives
  To delete a file (bypass the trash can) on any particular drive, create a file named ".Trashes" (no quotes) at the root of the drive. That file will replace the OS X trash can on the drive. This method works great on USB drives where you may want actual deletion rather than a trash can.
  
  You can do this from the Terminal app (Launchpad -> Utilities -> Terminal) using the following commands:
  cd "/volumes/USB DISK NAME/"
  rm -r .Trashes
  touch .Trashes
  The first command sets the location to the USB disk. The second command removes the existing trash can. The third command creates the special file which keeps the trash can from coming back.
• Browsing hidden directories
  OS X hides some directories (folders). This is done to prevent novice users from doing bad things. There are many techniques you can use to browse these directories, but the easiest is just to use Finder. Go to Finder -> Go -> Go to Folder, and enter the name of the folder you wish to browse. That hidden folder and all folders and files under it now become visible.
  
  You can also expose the hidden Library folder for your user by holding down the Option key when using the Go drop down menu in Finder. If you want to make your Library folder always visible in Finder you can hide, and unhide, the folder using the following commands from the Terminal app (Launchpad -> Utilities -> Terminal):
  chflags nohidden ~/Library/
  chflags hidden ~/Library/
  The first command will unhide the Library folder. The second command will hide the Library folder again.
• Edit your custom dictionary
  The OS X built-in spelling dictionary is a great feature. You can add words by selecting "learn spelling". But you may want to edit words that have been added, or add a bunch of words at once. You can edit the dictionary file directly using any text editor. The file is located in the Spelling folder within the Library folder within the user directory.
• Make a Lion Recovery USB Drive
  Built right into OS X Lion, Lion Recovery lets you repair disks or reinstall OS X Lion without the need for a physical disc. The Lion Recovery Disk Assistant lets you create Lion Recovery on an external drive that has all of the same capabilities as the built-in Lion Recovery: reinstall Lion, repair the disk using Disk Utility, restore from a Time Machine backup, or browse the web with Safari.
• Recommended Settings
  Here are a few recommended settings, along with the reason for making the change.
  • System Preferences -> Privacy and Security -> check "Disable remote control ...", that is unless you plan to use it.
  • System Preferences -> General -> uncheck "Restore windows ...", when closing an app is it a pain to have to close the document first.
