You can use Command plus the number keys to jump to the first, second, third, all the way up to the ninth tab in the current Safari window. But a new feature in macOS 10.13.4 is the ability to use Command+9 to jump to the rightmost tab. So if you have three tabs open, you can use Command+1 to Command+3 to jump to each, but Command+9 can also be used to jump to the last tab too.
If you hold the Option key down and click on the Time Machine icon on the right side of the Menu Bar, you’ll see that the command Verify Backups replaces Back Up Now. You can use this command to verify the integrity of your backup. This can be a handy reassurance if you are about to do something like use Migration Assistant to restore everything to a new Mac.
Sometimes it can be hard to remember where a setting may be inside of System Preferences. To find things, just search. Click on the Search box at the top right, or use Command+F. As you type, suggestions will appear and preference categories will become highlighted. Click one of the suggestions to jump right to that setting.
