Quickly Re-Type Previous Text In Messages App [OS X Tips]

By

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.

How To Repair & Verify Your Hard Drive From The Command Line [OS X Tips]

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.

And here you thought Terminal was just for Unix geeks.

Ok, well, maybe it really is, but there’s a fun easter egg or two hidden in the old UNIX code that underlies Apple’s OS X software.

Turns out that you can play Tetris and Snake, two classic games from the dawn of digital gaming, in a Terminal window. Intrigued? It’s super easy.

Go Ahead, We Don’t Mind: Put The Dock In The Corner On your Mac [OS X Tips]

By

Dock Upper Left

While no one puts baby in the corner, you can ignore that time-honored advice and actually put the Dock in the corner on the screen of your Mac.

While the traditional tools for moving the Dock around will let you move it to the right, left, or bottom of the screen, this little bit of Terminal magic will have the dock pinned to the far corners of your Mac’s screen, either the right bottom, the top left, or any other corner you can imagine.

Enable The Web Server In Mountain Lion [OS X Tips]

By

WebSharing

It used to be a no-brainer to enable the Apache web server included with Mac OS X. You’d hop into the System Preferences, fire up the Sharing preference pane, and then you’d be good to go.

Starting in Mountain Lion, however, Apple hasn’t given a user-friendly checkbox as in previous OS X releases. Instead you need a little bit of Terminal magic.

Here’s how to enable and start the Web Service in OS X Mountain Lion.

Use Single-User Mode To Solve Wonky Mac OS X Issues [OS X Tips]

I saw this tip over at OS X Daily today, and it reminded me of all the times I did this as a Mac IT guy a couple of jobs back.

See, every so often, the Macs where I worked would start to act weird. Nothing truly game-stopping — just little things, stuff that was easily worked around but always a little bit annoying. The first stop when things are weird, for me, was always Repair Permissions in the Disk Utility app. I’d usually then Verify the disk in that very same app, and see if it returned any errors. If not, I’d usually drop into single-user mode and do a file system check.

Here’s how to do just that.

Do It Your Way – Set A Custom Delay Period To Unhide The Dock [OS X Tips]

By

Dock Unhide Delay

I routinely hide the Dock on my Macbook Air, since it takes up a significant portion of my screen. While I use Alfred most of the time to launch apps and such, I still like to use the Dock; call it a hold over from the last ten years or so.

Sometimes, though, when I move the mouse cursor over to the side of the screen I keep the Dock on (the left, if you’re curious), it pops up even when I don’t want it to.

Then I found this Terminal command which lets me set the time delay between when my cursor hits the edge of my screen and when the Dock actually appears. Now I have the delay period set to a larger number, making it much slower to respond and unhide.
