iPhone not connecting to iMac

[baxlobs]

I have an iPhone 5SE, and an iMac late 2012, normally if I connect them via USB the iPhone shows up as a device in iTunes, and I can then back it up etc. However I tried today and it just does not appear. iMac is running Mojave 10.14.6, iPhone iOS 14.3
it occurred to me that maybe Mojave is not compatible with the latest iOS and just does not “see” the iPhone? What other reason might there be?

have you tried restarting your iPhone, and trying a different USB port or cable

Hi,

Thanks, yes I did restart it and tried a different cable, but oddly I just now plugged it in to charge it overnight to the Mac rather than a mains charger, and lo and behold it has synced and backed up!! Must have been finger trouble or a grubby contact?

Could still be a dodgy cable. You might need to clean the lightning port on the iPhone.

It could also be dust in the lightning port you can blow into it or get a dust blower, these locks phone shops usually do it for free
