In /var/db/diagnostics folder there are some compressed binary .tracev3 log files.

How can I read them what is inside in a formatted way?


Ok, I've found that using log command will read these files in a formatted way, e.g.

log show file.tracev3 | less

  • @Doug If you've got a command line access on your iOS (jailbreak), possible. On Windows, not, unless you can log in into macOS machine (VM or remote), or there are some external tools for Windows reading these kind of formats. – kenorb Jan 30 '18 at 16:06
  • I have a jailbroken phone. I don't see the log command on it, but I'm trying to track down a binary. Hopefully I'll get lucky :-). – Doug Jan 30 '18 at 16:07
