If you use an Apple MacBook or an iMac, then enabling JavaScript on your computer will depend on the browser you prefer to use. Most Mac users prefer to use Safari as their primary browser. You might also use Firefox or Safari on your device. Enabling JavaScript in any of these browsers requires a specific set of actions that you must follow sequentially.

  1. Enabling JavaScript in Safari on a Mac
  • You will need to launch Safari after your Mac goes through its full startup cycle.
  • Once the browser displays correctly on your system, choose the Safari menu option at the top left of the display.
  • Then you will want to click on the Preferences choice in the drop-down menu that displays. You will then have a pop-up window that eventually appears on the screen.
  • If you are running multiple applications at once, the spinning rainbow wheel may appear for a few moments. This action is normal.
  • Choose the Security icon in the middle of the pop-up window that appears. You will be given two options, with the bottom selection asking to Enable JavaScript. Make sure the box is checked. Then you can close the pop-up window.
  1. Enabling JavaScript in Google Chrome on a Mac

If you prefer to use Google Chrome on your Mac, then launch this browser after your device’s startup cycle is complete.

  • Go to the Chrome option on the top left of the display. Then choose the Preferences option that appears on the drop-down menu.
  • Then you must select the Show Advanced Settings option from the next menu of choices that appears on your Mac. Once you get into this window, select Content Settings, which you can find in the Privacy section.
  • You will then need to click on the Allow All Sites to Run JavaScript (Recommended) radio button in the appropriately marked section. Then you can close the window to use Chrome successfully.

  1. Enabling JavaScript in Mozilla Firefox on a Mac

If you use Mozilla Firefox as your primary browser on a MacBook or iMac, then you will want to launch it after your device completes its startup cycle.

You cannot access the advanced settings to enable JavaScript from the drop-down menus found in this browser’s latest updates.

  • When the browser opens the empty default window, you must type about:config into the URL address bar. Press the Return key to initiate the command.
  • Firefox will then issue a warning that changing any advanced settings could void your warranty. You must click the I’ll Be Careful, I Promise button.
  • Then type JavaScript:enabled into the search bar. You can find it underneath the URL address bar, but above the list of commands that will display on your screen.
  • Double-click the option that appears so that it toggles between a “true” and “false” value in the browser window.
  • When it is set to “true,” then JavaScript is enabled on your Mac. Then you must reload Firefox for the changes to go into effect.

If you do not see changes happen, then close your preferred browser. Launching it a second time should give you the needed result. Some users may need to restart their Mac as the final step to enabling JavaScript.
