How do I delete Time-Machine back-ups on external HD
Hello everybody, I would like to delete all the Time Machine back-ups on my external hard drive and create a new full back-up. This is because after several months my HDD is quickly filling up and I would like to clean out all the old back-ups. What is the best way to do this? Sould I simply delete the old back-ups through finder, or is there another and better way to do this? Many thanks for your help!
