@corlin In 2020 My network and everything attached was compromised. It was hard to get Apple to listen at first. After looking at the System Information report under Applications, I noticed blocks of Apple software listed updated at the same time with insanely high Version numbers. Then compared them to my reinstall log. They had been passed over because they were a newer version then the current install. After that they took it seriously, they ended up having me call the police.
Sorry to hear that.
Hope all is well now.
I don't know how technical you are.
But Mac OS does have an extensive log system. That greatly helps trouble shooting. I use this to access log files.
Mints – collection of custom log browsers and tools
@corlin I can’t code or even use scripts. I’m an analyst by profession though so I’m good at looking through vast details that don’t always make complete sense and find connections or things that stand out.
That what this piece of kit helps with. Gathering information so one can analyze it. It is pretty extensive and has a fairly high learning curve, but once you solve a problem with it. You will keep it in your toolkit.
@corlin I have extensive backups of system files and logs at several different levels, then each collection with any screenshots written to an SD card locked and dated. I might not have a clue but I am a total digital hoarder just in case. Then the cards go in a brown envelope the size of a business card that has the Admin login and password I was using at the time of the backup. I might not be technical but I’ve learned that the more documentation you have saved can help later.
