@sweetp Hi Russell, For other reasons I've had to rollback from Big Sur to Mojave of which I have the latest update, 10.14.6 (18G7016). I have installed Cookie 188.8.131.52. There is still an issue with this which may be a permissions problem. Even though I've unchecked the Apple website as a favourite, I still cannot delete the cookies.
Sorry I didn't get back to you sooner, thought there would be a notification of your reply. Cheers!
