5 ways to take a screenshot

If you want to show someone what’s on your screen (perhaps in order to give or receive technical support), there are many ways to capture an image that shows all or part of your screen, for sharing with others. Here are five practical methods for grabbing a screenshot.

  1. Full screen To capture an image of your entire screen, simply press z-<Shift>-3.
  2. Selected area To capture a selected area of the screen, press z-<Shift>-4, and then drag the rectangular marquee around the area that you want to include in the screenshot.

Most screen-grab utilities let you capture a whole window or all or part of the screen

  1. Window or object To capture a window, a menu, an icon, or any other on-screen object (along with its drop shadow, if there is one), press z-<Shift>-4, press the spacebar, and then click the object that you want to obtain a screenshot of. The preceding three commands (for full-screen, selected-area, and window or object screenshots), save the captured image as a file on your desktop. If you would prefer to copy the image to your Clipboard, add the <Control> key to the shortcuts listed above.
  2. Grab For more capture options – including a time-delay feature, the ability to choose how the cursor appears, and the option to have your system emit a confirmation sound when you make a capture – use the Grab app that comes built in to OS X (in /Applications/Utilities).
  3. Third-party utilities If you need more capabilities than OS X’s Grab can provide – for example, the ability to specify file formats on the fly, or to scale a screenshot’s size – you have many screen capture utilities to choose from. Among the most popular of these are Ambrosia’s Snaps Pro X ($69,, Realmac Software’s LittleSnapper ($40,, and Skitch (free, plus account, $20/year,

2 ways to share screen

If your Mac is set up on the same local network as the Mac that you wish to control remotely, you just need to ensure that Screen Sharing is enabled on both Macs

If your Mac is set up on the same local network as the Mac that you wish to control remotely, you just need to ensure that Screen Sharing is enabled on both Macs

  1. If your Mac is set up on the same local network as the Mac that you wish to control remotely, you just need to ensure that Screen Sharing is enabled on both Macs (System Preferences ð Sharing ð Screen Sharing). In a Finder window’s sidebar, select the Mac you wish to control or view, and then click Share Screen. Enter a username and password for the Mac that you intend to control (or choose to log in with an Apple ID supported by that Mac). You should be screen-sharing in to time.
  2. Remotely If you want to control a Mac that isn’t on your Mac’s local network, sign up for a free AIM account ( on each system, using a different account for each. On each computer, launch the Messages application; in its Accounts preference, click the plus (+) button and configure your AIM account. Click the Video menu, and select Screen Sharing Enabled on both Macs. Now, when each Mac has Messages running, you can select the other Mac and choose to share its screen. Alternatively, you can sign up for a free LogMeIn ( account. Install the free LogMeIn server application on any Mac you wish to screen-share with, and you can access and control that Mac through a Web browser.


2 ways to make a clean migration to a new Mac

When you get a new Mac, you may want to transfer some of the apps and data from your old Mac, but leave behind all the useless Cruft and clutter.

Unfortunately, you have no clean way to transfer only the specify applications and data you want while still guaranteeing that all necessary components and files are preserved. That’s because many OS X apps not self-contained. Instead, they store pieces in a variety of folders and sometimes these pieces are invisible or have hard-to-identify names.

Reinstall your critical apps by downloading them again or using fresh copies

Reinstall your critical apps by downloading them again or using fresh copies

  1. Use Migration Assistant The easiest and most reliable way to move stuff to your new Mac is to connect the two Macs with a FireWire or Ethernet cable and use Migration Assistant. You’ll find this utility located in /Applications/Utilities; it’s built into the Setup Assistant that runs automatically the first time that you turn on a new Mac.

Regrettably, Migration Assistant lets you select or deselect only board categories of things to move; you can’t, for example, choose some apps but not others, or only a few subfolders within your Documents folder.

  1. Reinstall apps As a compromise, I suggest that when running Migration Assistant, you deselect Applications and Other files and folders on [Volume Name], but leave Settings and all its subcategories selected along with all the user accounts and their corresponding subfolders. Finish starting OS X and then log in.

Now you can reinstall all your critical apps in two ways: You can either download them from the Mac App Store, or use fresh copies that you obtained directly from the developers.

This process may take a while, but it will lead to much less clutter, and it will allow you to enjoy the latest, most up-to-date apps.

In case you are not able to install an application from scratch for some reason, you can run the Migration Assistant utility a second time. This round, select only Applications and let the utility copy everything (including all the extra clutter).

6 ways to troubleshoot a Web Connection

If you can’t get to a webpage, try the following steps.

  1. Check your internet connection The first thing to do is to confirm whether you can access other websites. If you can, your connection is fine.
  2. Check the Wi-Fi menu This is to make sure your Mac hasn’t dropped its connection; if it has, try reconnecting.
  3. Try another device If another Mac, an iPhone, or an iPad on the same network can connect to the website that you are having trouble with, then restart your Mac and try again.

If this doesn’t work by restarting your DSL or cable modem followed by your AirPort base station or other Wi-Fi router, if any. If you do all that and your connection is still down, it’s time to call your Internet service provider.
