Whenever you Mac starts up you can set your most frequently used Applications to automatically open.This will ensure that once you login that you won’t have to go clicking through icons to get your Apps to open, they’ll be right there waiting for you when you login.
All you have to do is open System Preferences and click on the Users & Groups tab in the lower left hand corner. Once you’re here you can choose the Account that you would like to have items open upon login. After you’ve selected the Account that you would like to use click on the Login Items tab in the upper right side of the screen, here you’ll see a list of Apps that are currently set to open upon login. Clicking on the “+” below the list of Apps will allow you to add an App from your Mac to automatically open upon login. You can remove an App by selecting it from the list and then clicking on the “-” button below the list. In the list you’ll see the option to Hide an App, what this will do is open the App but hide the window so you don’t see a bunch of windows opening up when you login in.
