How to view activity logs of iPhone and iPad on Mac
iPhone and iPad create a record of some system activity, including application problems and other interesting or useful data. By connecting an iOS device to a Mac computer, you can review those logs.
Although viewing log data is usually only useful for developers and advanced users to diagnose, troubleshoot and create better applications. However, for non-professional users who are curious about everything, exploring device logs can also bring about interesting things.
To view the iOS device log you need an iPhone / iPad, a Mac and a USB cable. Make sure your iOS device is turned on.
How to view iPhone and iPad logs on Mac
- Connect iPhone or iPad to Mac using USB cable. Remember to unlock your iOS device.
- Open the "Console" application on Mac OS, then find / Applications / Utilities / Directory.
- From the sidebar of the Console application, see the Device section and select the iPhone or iPad connected to the Mac.
- Log data will be displayed immediately.
Log data will be updated immediately when actions occur on iOS devices. For example, when you connect to a wi-fi, disconnect from Wifi, turn off the mobile connection, open or close the application, start a process that you know will happen, data related to those events will appear immediately on the screen. For the average user, this may not work, but it is really useful for developers.
If you connect multiple iOS devices to your Mac, you can browse the logs for each device independently. If you have synced the Apple Watch with the connected iPhone, you can also view the Apple Watch log via the Console app on the Mac in the same way.
Note: If you choose an iPhone or iPad from the Console application and have no data instead, the "!" next to the device name in the list. This means that you must unlock the device and the connected computer to be trusted.
If you ever untrusted the computer or reset the list of trusted computers in iOS, you will need to install the computer trust before displaying the log. Similarly, if you ignore the "Trust This Computer?" Dialog box, you can reactivate by connecting and disconnecting.
