i thought the error page would be connected to my question.
below is what my question was referring to::
"If you see "Software update is required to connect to your iOS device" on your iPhone, iPad, or iPod touch
When you connect your iPhone, iPad, or iPod touch to a Mac with macOS 10.11 or later, you might need to update the software on your Mac in order for it to recognize your iOS device. Learn what to do.
If your iPhone, iPad, or iPod touch has a newer version of iOS than is supported by your Mac, you may see this alert: "A software update is required to connect to your iOS device. Would you like to download and install this update now?"
so my question, again:
my macbookpro is Sierra 10.12.6. what is the update to be downloaded? is it just a minor update to existing OS or is it a newer version full OS??
