Q: Why apple come up when I lodge on to wifi

Hello Donald,

You may have that set as your homepage.  If you are using Safari, you can update your homepage by following these steps:

Your homepage is the page that normally appears when you first open Safari.

1. Open Safari if it is not already open.
2. Choose Safari > Preferences, and then click General.
3. 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.
4. 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.
