Silent key logger
I am a victim of domestic violence. My ex put perfect key logger for Mac on my old MacBook. I removed it some years ago but now I need evidence it was on there for court. I have IMs of him admitting it and how to remove but I wondered if there was a digital footprint of exactly when it was installed? He was FTPing all my data to his ex gfs shared hosting space. He maintains he never had my banking passwords or financial records but I know he harvested all of my email going back years. So not new key strokes - maybe using passwords?
Please be kind in responses, I realise that some things may not be accepted as evidence but after PTSD treatment I feel having the full facts and proof it really was on there would be good closure. And am ready to deal with this legally.
Thanks for any help and being kind.
