I'm sorry about the issue. In Safari app on your computer, click on the Safari menu at the top, then click on Preferences
, then click on the General tab at the top, then if the Homepage box is wrong, then delete it, and leave it blank or type in a website you want, such as google.com or yahoo.com etc.
, then click on the Search tab at the top, then change the Search engine option to anything you want, such as Google or Yahoo etc.
Please reply at the box below to continue troubleshooting. Thank you.
