Device not showing in iTunes
When I connect my iPhone 8 Plus to iTunes, it never comes up in iTunes. The help information says:
If you use a Mac
- Connect your iOS device and make sure that it's unlocked and on the Home screen.
- On your Mac, hold down the Option key, click the Apple menu, and choose System Information or System Report.
- From the list on the left, select USB.
- If you see your iPhone, iPad, or iPod under USB Device Tree, uninstall third-party security software. If not, contact Apple Support.
My iPhone shows up under "USB Device Tree". I didn't know I have third-party security software, but if I do, I don't know how to locate it and/or how to uninstall it. Any help is appreciated. I have iOS 10.13.6 but it was not one of the choices below.
iPhone 8 Plus, iOS 10.3.3, I am on iOS 10.13.6
