I've seen a few people with LogMeIn issues be given advise to check the box next to LogMeIn in the Privacy tab of the Security & Privacy pref pane. My question is why does LogMeIn need "Full Disk Access"? Or what affected if I don't grant this permission? My setup seems to be working fine for both host & client without this box checked.
Hmm i'm not sure that's it. I have LogMeIn *unchecked* in the Full Disk Access section of Security & Privacy and I'm able to select and generate a link to share files. It even works with files outside of my Home folder.
In that case I may be wrong, but I'll add that we typically ask for full permissions from Apple just in case they change another security policy in the near future. It's entirely possible that permission is not needed at this time.
