Your homepage is the page that normally appears when you first open Safari.
Open Safari if it is not already open.
Choose Safari > Preferences, and then click General.
Do one of the following:
To use the page in the current Safari window or tab, click “Set to Current Page.”
To use another page, type its address in the Homepage field.
To use a blank page, delete the contents of the Homepage field so that the field is blank.
If you also want the homepage to appear whenever you open a new Safari window, choose Homepage from the “New windows open with” pop-up menu.
