Step 1: Swipe Settings
Launchpad will open with a four-finger pinch on your trackpad. Right now you can’t launch it with a Magic Mouse Gesture, sadly.
Step 2: Hardware
All new MacBook Airs and wireless keyboards have a hardware button on the F4 key that opens Launchpad with a tap rather than a swipe or a click.
Step 3: Apps
Launchpad’s first page contains your pre-installed apps. When you download more from the Mac App Store, they’ll be added to the next page by default.
Step 4: Swipe at the pages
Swiping across the trackpad with your finger (or fingers) will show you the next page of apps. It’s like the iPad Home screen.
Step 5: ’Wobble Mode’
When you click and hold on a single app, all the icons will start to shake and you will be able to delete those that you bought in the Mac App Store.
Step 6: Making a Folder
You can drop app icons on top of others to create a folder. You don’t need to be in Wobble Mode to do this, unlike on iPad where it’s mandatory.
Step 7: Rename the folder
When you drop the icon in it will intelligently name the folder based on the apps that you have included in it. You can rename it by clicking the title.
Step 8: Delete
Deleting an app is just as easy – click and hold until crosses appear in the top-left corner of icons, then click one to remove it. You will be asked to confirm.
