If iPhone is not coming up with “Trust This Computer” pop-up when connected to Mac or PC, you can find below the steps to fix this problem.
Trust This Computer Not Showing Up on iPhone
iPhone should come up with “Trust this computer” pop-up, when it is connected to Mac, Windows computer or Chromebook for the first time.
Once you authorize the computer by tapping on the Trust option, it practically gains the right to access Photos, Contacts, Messages and other data on your iPhone.
Hence, the purpose of “Trust This Computer” pop-up is to protect your privacy and data by making sure that you are connecting your iPhone only to known and trusted computers.
If “Trust This Computer” pop-up is not showing up on iPhone, you may have already trusted the computer or unknowingly tapped on the “Don’t Trust” option.
Apart from this, the problem could also be due to USB Port being faulty, the version of iTunes being outdated and network related issues.
1. Unlock iPhone
iPhone won’t be able to show “Trust This Computer” pop-up, if its screen is locked. Hence, unlock your device and it should come up with Trust This Computer pop-up.
2. Replug iPhone into Computer
Unplug iPhone from the Computer > Wait for 30 seconds > Plug iPhone back into the Computer and see if it now comes up with “Trust This Computer?” pop-up.
3. Try Another USB Port
As mentioned above, the problem could be due to the USB Port being disabled or not working properly. To confirm, plug iPhone into another USB Port and see if it helps in fixing the issue.
4. Restart iPhone
Sometimes, the problem is due to a minor glitch or stuck process preventing iPhone from coming up with its usual Trust This Computer pop-up.
Go to Settings > General > scroll down and tap on Shut Down.
Allow iPhone to completely shut down > After 30 seconds Restart iPhone and plug it back to the computer.
5. Update iPhone
Sometimes, the problem could be due to a pending update waiting to be installed on your device.

On the software update screen, tap on Download and Install (in case a software update is available).
6. Update iTunes
If you are connecting iPhone to a Windows computer, make sure that the latest version of iTunes is installed on your computer.
Open iTunes on your computer > click on the Help tab in top-menu bar and click on Check for Updates option.
Wait for the computer to check and install the update on your computer (if available).
7. Reset Location and Privacy
