Hi @LarryWaterhouse, welcome to the LE community forum 
Fixed it for you
I'll try to focus my reply on things specifically yet uncovered...
How useful was the laptop prior to this event? (maybe I'm missing something here - I don't MAC)
Which uses have actually been rendered useless? I can only think of one (but, again, no MAC here).
So.. you may have to use another browser until:
- Apple fixes the problem or allows others to do so (I wouldn't hold my breath)
- You get used to some other browser and life resumes (for the laptop - with that bit less useless)
It's really not the end of the world - just the end of the incredibly insecure world we once lived in.
Welcome to the future
