12476486739033557300 asking for access to safari

Thank you K Shaffer. I guess you were right.

I wiped my Mac clean and reloaded the OS. And Malwarebytes + Avast.(Really do not know if that is the best thing. Apple support recommended Malwarebytes. And I already had Avast subscribed.)

And then restored all needed files from a back up. That shady long number asking for Safari access has vanished. My battery lasts a little longer. And no more messages popping up saying there is low memory (while I knew I had 40 gigs free).

Apple support on the phone was spot on with the help.

Probably was Malware.... and taking up too much battery, memory and peace of mind!
