It’s really annoying that many Apple keyboards dont have a # hashtag. This is especially annoying when you tweet a lot and want to emphasise or tag your post with a hash tag using a Mac………I suggest using a post-it note on your monitor with the following written on it.

# = Alt + 3

€ = Alt + 2

© = Alt + G

• = Alt + 8
