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.
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 you’ve got a UK or European keyboard and find one day that the hashtag key suddenly types a pound sign instead or the hashtag when you use the Alt-3 combination, it’s probably because the keyboard language settings have reverted to US instead of UK after an update to macOS.
If this happens follow these instructions to change it back to a UK British layout:
- Go to the Apple () Menu > System Preferences.
- Select Language and Region.
- 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.
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.
