How to Allow a Pop-Up on a MacBookby David Perez
A pop-up is a Web page that opens in a browser window other than the one you're currently using. Many users consider them undesirable because they tend to display unwanted advertisements and can cause the desktop to become cluttered with unused windows. You can control the way your MacBook handles pop-up windows through your Web browsing software. Note that if you want to enable pop-ups altogether you must do so on all Web browsers installed on your MacBook.
Open the Safari Web browser from the Applications folder.
Click the word Safari at the far left of the toolbar at the top of the screen. This displays a drop-down menu. Some versions of Safari provide an option reading "Block Pop-up Windows." If there is a check mark to the left of this option, Safari is blocking pop-up windows. Click the option. This removes the check mark, indicating that pop-up windows are no longer blocked.
Select Preferences from the Safari drop-down menu, if the "Block Pop-up Windows" option does not appear in the main Safari menu. Select the option labeled Security from the menu at the top of the toolbar. The option appears as a padlock. Locate the option reading "Block pop-up windows."
Note whether the check box to the left of "Block pop-up windows" has a checkmark. If so, click the box to remove the check, indicating that pop-up windows are no longer blocked.
Click on the Firefox drop-down menu at the far left of the toolbar at the top of the screen. Choose "Preferences" from the menu. This opens a window with a list of options at the top. Select Content from this menu. This option appears as a Web page with text and images. This displays a new list of options.
Note whether the check box to the left of "Block pop-up windows" has a check mark. If so, click the box. This removes the check, indicating that pop-up windows are no longer blocked.
