Here’s a handy little tip if you shut down your Mac with the options in the Apple Menu.
Typically, when you choose Restart or Shut Down from these menu options, you’ll get a dialog box that checks to see if you’re absolutely, positively sure you meant to choose the menu option that you just…chose…sigh.
When you’re using iTunes in list view to see all your songs listed in order, you can sort that list by the columns across the top.
If you notice, there’s a little checkbox to the left of each track. These checkboxes tell iTunes when to use the tracks or not, like when you’re ripping CDs, using the Match Only Checked Items Smart Playlist option, and when syncing to your iPhone. If you uncheck a song, it won’t be burned to a CD, added to a specific Playlist, or synced to your iPhone. To make that happen, simply click on the checkbox to the left of any track and it will be unchecked.
But what if you want to uncheck more than one track at once?
When you’re typing in Terminal, it’s easy to access the commands you’ve previously typed with the Up arrow on your keyboard. This can be handy when you have to re-type a long, complicated command. Simply hit the up-arrow and you’ll get the previously entered command.
Hit the up-arrow again, and you’ll get the command you entered before that, and so on, cycling through in reverse order until you get to the very first command entered in that particular Terminal window.
Turns out, you can do a similar thing in Messages, too.
There are quite a few web sites these days that will send you notifications when you visit them via Safari. Sites like NBA.com and the New York Times will drop you a dialog box when you visit them for the first time to ask you if you would like to receive the push notifications.
If you allow them, all hope is not lost should you reconsider your decision. You can drop right into System Preferences and disable them on a site by site basis.
When you launch Safari on OS X Mavericks, you’ll typically get a set of thumbnails of web sites you’ve visited, called Top Sites. The default set is twelve thumbnails, but if you hop into the Safari preferences, you can set it to display six, 12, or 24 Top Sites.
OS X offers a very nice graphical user interface to verify and repair your hard drive, located in the Utilities folder. It’s called Disk Utility, and you can use it as the first line of defense when weird disk-related things happen to your Mac’s hard drive.
If, however, you want to dig in a bit deeper, or you’re already running Terminal a lot and don’t want to launch a separate app, you can use the following commands to both verify (check for problems) and repair any problems that you might find when verifying.
