I have NOT updated macbook at all since I bought it in 2020. I lost 'everything' with my previous macbook in the process of 'updating' (with Apple technical support assisting me the whole way through!) and I am so scared of any updates. I suppose there is no other way - ? (These seems to be no older version of WhatsApp available as far as I could see.) I'm just not up to date with any changes and really puzzles me one day after one hour, green logo just went grey (do people like me exist? I really hate updating......and avoid any updates if at all possible) Thank you for offering solutions though. I really must try.
