Answer 1

  If you don’t have another browser installed,
Shut down the computer.
Press the power button. Immediately after you hear the startup sound, press and hold the Shift key.
The Shift key should be pressed as soon as possible after startup,but not before the startup sound.
Release the Shift key when you see the Apple logo on the screen. Startup will take longer than usual.
Login to your account. Launch Safari.
