- System Requirements
Your iPhone requires specific system requirements for compatibility with Macs. For instance, the iPhone 5 pairs with Mac OS X v10.6.8 and later for iTunes 10.7 or later. Confirm your iPhone’s operating system specs for your Mac.
Also, examine your Mac’s existing operating system by going to Apple icon in the upper-left corner of your screen and choosing “About This Mac”. Update the operating system to upgrade it to your iPhone’s minimal requirements and restart your Mac.
- USB Ports
iPhones and iOS devices require USB 2.0 to link properly to your Mac. Ensure your Mac specifications reveal a USB 2.0 port. If present, try unplugging and reconnecting your iOS directly to a Mac’s USB 2.0 port rather than the keyboard’s connection or hub. Pair your cable to every USB 2.0 port on your Mac, and check if it detects the connection. Otherwise, use another USB cable and retry all ports.

A buildup of unwanted content, digital dirt, and traces of purged applications gobble up space meant for essential files, which means your machine runs out of steam.
