When you first turn on your Mac, there may be other programs that start up at the same time besides the operating system. Some of these programs do not need to start up each time and turning them off can really help, not only the startup performance, but the overall performance of your machine.
Here is how to manage your startup programs.
Open System Preferences and select Users & Groups. Next, click the Login Items button near the top of the box. Here you will see a list of items that are starting up when you log in. To remove one, select it and then click the “-“ icon below. You can do this for each one listed.
What if you do want to have a particular application start up because you use it every day, all day? For example, perhaps you use the calculator or your calendar often throughout your day. To add an application, click the “+” sign and Finder will open to the Applications folder.
Here you can scroll through the list and add those apps that you want to start up at log in. Select the application and select Add. If you change your mind about these startup apps, just return to make the changes.
To change the startup appearance of your desktop, in System Preferences, select Desktop & Screen Saver.
Select the Desktop tab near the top and then in the list on the left, select your background. I decided to go plain and I selected Solid Colors.
At the bottom of the box, you can choose to have pictures from your selected folders, change either in order or randomly and you can choose how often to change the picture. Click the arrows to make your interval choice.
If you want to use the screen saver, click the tab at the top of the box. At the bottom-left, you choose when to start the screen saver. Click the arrows and make your choice. Try out the many possibilities to find the right one for you and then you can close the system preferences box.
