@Steveh100 well, there is your problem. You have an infected Apple Mac. “CleanMyMac” is a nasty bit of scamware.
For other readers - this is not a Picard issue. Everything below here is boring to read unless you want to know about infected Apples.
Funnily enough, the client’s Apple Mac I am looking at this weekend was infected with that scam last month. He had a few like that on there. And between them they had knackered his Security System. I know when I was trying to install correct anti-virus tools they were being fought off by CleanMyMac breaking the “apps from unidentified developers” section thereby stopping any other apps from being installed. In this case, specifically the proper scam cleaners.
I expect that is the point that is failing on your Apple when trying to install Picard.
I’ll be straight with you - that was a messy cleanup. I had to do a part manual clear up, and then throw a couple of different malware scanners at it. Finally finishing up with quality anti-virus. Shocking volume of items pulled out in the end - and all related to each other.
Kinda funny that for years Apple had this “we don’t get infected” attitude… and in this past 12 months I have cleaned up more infected Apple computers that Microsoft!
What is hitting Apple now is like ten to fifteen years ago on Windows. These are applications that claim to help, but really do the exact opposite. Not exactly a “virus”, just a plain old fashioned scam.
I hope you have never paid for it?!
And if you want actual clean-up assistance then I can offer my services. Don’t let the comedy name fool you - I am UK based and can run remote clean-ups using remote access software.
