Log Locations
macOS:
~/Library/Logs/CrashReporter/MobileDevice/[Your_Device_Name]/DiagnosticLogs/sysdiagnose
Notes: “~/Library/...” actually translates to: /Users/[Your User Name]/Library/...
The “/Users/[Your User Name]/Library/...” folder is hidden by default in macOS. To expose the folder, hold the option key while clicking the Finder’s Go menu and the Library folder will appear in the menu. Any time you see a placeholder like “[Your Device Name]” or, “[Your User Name]” you should replace that part of the path with your actual device’s name, or your computer user name.
Windows:
C:\Users\[Your_User_Name]\AppData\Roaming\Apple Computer\Logs\CrashReporter\MobileDevice\
[Your_Device_Name]\DiagnosticLogs\sysdiagnose
Note: The AppData folder in Windows 8 is hidden by default. Click on the View menu item in a Windows navigation window and check the "Hidden items" checkbox and the AppData folder will appear in the list of folders under C:\Users\[Device_Name].
Important: Replace "[Your_Device_Name]" or "[Your_User_Name]" in the file paths above with the actual device name for the iOS device, or the actual user name you use on your computer.
