I'm sorry about the issue. Can you please open Safari application, then click on Safari menu at the top, then click on Preferences, then click on the General tab, then on the right of the option Default web browser, click on the dropdown list, click on the option Safari.
- If that does not work, please click on the Apple logo / menu icon at the upper left corner of the computer's screen, then open System Preferences, then open General, then choose Safari for Default web browser.
If that does not work, can you please confirm if you have Mac OS X version 10.6, 10.7, ..., 10.10, 10.11, etc.?
Or is it a different device?
Please reply at the box below to continue troubleshooting. Thank you.
