How to Take a Screenshot Using Timer

This is by far the best feature that Grab offers. It allows you to take a screenshot after a short period of time (10 seconds), and here is how to use it. Click on Capture on Mac’s menu bar and choose Timed Screen or use the keyboard shortcut Command+Shift+Z. Now click Start Timer and Grab will take a screenshot of the entire screen 10 seconds later.

After taking the screenshot, you can see information about it by clicking Edit on Mac’s menu bar and choosing Inspector. This also have a dedicated keyboard shortcut – Command+1. Here you can see your image’s view depth and size. By default, Grab saves all the images in TIFF format. However, you also have JPEG and PNG as variants when saving the image. Lastly, you can use the Preview app to make any changes to your screenshots like cropping, resizing, etc.

Screenshots Quality

Many of us have specific requirements when it comes to screenshots quality, like using particular file formats or some resolution standards. As the native format for Grab screenshots is TIFF, the images are fairly high-resolution. However, Grab is making screenshots of your screen, and if the resolution of your screen is 1080p, you cannot expect 4K images from it. That means your display resolution limits the Grab possibilities.

If this confuses you, let’s take a different approach at the situation. Grab captures the actual pixels on your screen. So, if the resolution of your screen is 2880×1800, all the full-screen-capture images will be with the same resolution. To make sure you get the best results of your display, go to System Preferences open Displays and check if you are getting the highest resolution available for your monitor.

Screenshots Image Format

The default and most used image format on Macs is usually PNG. However, you can quickly change that in whatever supported format you want, using Terminal. Macs support most of the popular image formats out there like JPG, PNG, GIF, TIFF, and PDF. So, you have a wide variety of options here.

Here is how to set a default image format using Terminal.

  1. Go to Applications, open Utilities, and doubletap the Terminal
    1. To change the default format to JPEG, type the following text in Terminaldefaults write com.apple.screencapture type jpg
    2. For TIFF, type “defaults write com.apple.screencapture type tiff
    3. To change it to GIF, write “defaults write com.apple.screencapture type gif
    4. If you want PNG to be your your default image file format, type “defaults write com.apple.screencapture type png
    5. And, for PDF, type “defaults write com.apple.screencapture type pdf
  2. The changes you have made do not make any effect until you restart your Mac or use additional Terminal action “kill SystemUIServer” Make sure you do one or another way and your default image format will be changed.

Grab Does Not Work After Updating Your macOS or OS X?

If your Grab app does not work after an OS update, the preferences file of this app might have gotten corrupted. However, here is how can you check and fix this issue.

  1. Open Finder, navigate to Mac’s bar menu, and select Go.
  2. Now, choose the Go to Folder option, and a new bar will show up in your Finder.
  3. Write in the following: “~/Library/Preferences/com.apple.Grab.plist and hit return
  4. Move the file to your Desktop or to the Trash and restart your computer.
  5. After your Mac turns on, try Grab If it works, you can delete the old preference file from your Desktop or Trash.

If this procedure for updating the preference file did not work for you, reinstall the Grab app using macOS Recovery and then reinstall macOS or OS X.

Additional Screen Capture Option on macOS and OS X

If for any reason you don’t want to use Grab, try using your standard keyboard shortcuts for screenshots. To capture entire Mac’s screen press Command+Shift+3. For capturing a specific area of the screen using crosshairs, press Command+Shift+4. The screenshots are automatically saved as image files on your desktop. If you don’t want to save them to your desktop, just press the control button, and the images will save to your clipboard. After that, you can easily paste into other applications using the Paste option (Edit and Paste, OR Command+C).

If you cannot make screenshots using the keyboard shortcuts, make sure they are enabled in your Mac’s default keyboard shortcut menu. Go to Preferences, choose Keyboard, and tap on the Shortcuts tab. Look at the left panel for the Screenshot option. On the right-side panel, make sure you have enabled the boxes next to the options for screen captures.
