Trust request error 0xE800009A
I'm just trying to connect my iPhone to my Mac.
When I click on the Trust button through the Finder I get the following error: "Trust request error 0xE800009A"
No trust this device dialog appears on the device.
I've gone through the steps here: https://support.apple.com/en-us/HT204095 but to no avail.
Any ideas anyone?
