How To Type A Hashtag On Mac Keyboards

It might seem strange but Mac keyboards don’t have a dedicated hash key # like PC keyboards do. Those that have recently switched to Mac can end up tearing their hair out trying to find out how to type something as simple as a hashtag on Mac for Twitter. The confusion is often because US and UK Apple keyboards are slightly different. Here’s how to type a hash on a Mac keyboard.

1. On US Apple keyboards, hold down the Shift key and press the number 3 key. You’ll see the hash symbol above the number 3 key on your keyboard.hashtag on mac - us keyboard


2. If you’re using a UK or European Apple keyboard, hold down the Option key (also known as the Alt key) and press the number 3 key. You’ll see the hash symbol to the right of the number 3 key on your keyboard.

If this happens follow these instructions to change it back to a UK British layout:

  1. Go to the Apple () Menu > System Preferences.
  2. Select Language and Region.
  3. In the list of languages, simply drag your preferred language to the top i.e. UK British. If you don’t see English (U.K) in the list, simply click on the “+” symbol to add it to the list. where is hashtag key mac - mac language preferences

When you close the system preferences, you may be prompted to restart your Mac for the changes to take effect.

Using Alt+3 will now type the hash again on British keyboards.

This is a simple tip but it’s sometimes surprisingly frustrating for first time Mac users that are used to the dedicated hash key on PC keyboards.

    Just comment to you young whippersnappers.
    US keyboards have always had the ‘pound’ sign on the ‘shift 3’ key. As far as ‘ hashtag’ goes the is a use of the ‘pound’ character in programming. People started using it the social media and I bet half of people today do not know it was used as pound symbol first. ‘#’ is an ASCII character (0x23 hex, 035 decimal), regardless what you call it.
