I had to switch temporarily to a MacBook Pro 13 early 2011 model and when I'm connecting my iPhone 7+ or iPad, it's not getting detected nor charged.
Other USB devices like thumb drives or USB-microphones are working just fine. If I put a voltcraft USB power converter between the iPhone/iPad and my MacBook Pro, the device is getting charged but it's still not getting detected in iTunes/duet. I already reset NVRAM (https://support.apple.com/en-us/HT204063) as suggested in similar posts here but that didn't fix anything and I don't know what else to try.
Any ideas? Thanks
