I have a problem with a swipe back in Safari. On my MacBook I could fix it by resetting of NVRAM. I can't find out how to do it on iMac with a Bluetooth keyboard. Do I really need a cable keyboard in order to reset it?

  • I've reset the NVRAM on my iMac with BT keyboard with no issue. You have to turn on the iMac and then hold down the keys before the startup sound/logo appears. If you still have a problem resetting it, try entering nvram -c to reset the NVRAM variables via the command line. Then reboot – Allan Feb 13 '19 at 15:03

This can be reset using Terminal.

  1. Launch Terminal from the Utilities folder

  2. Run the command:

sudo nvram boot-args=”-p -r”

  1. Press Enter

  2. Type your password

  3. Press Enter again

  4. Restart your computer

After a restart it should be reset.
