iPad won't connect to MacBook air (keeps flickering in and out of charge)

I need to connect my iPad to my Mac in order to install the new security software fix (my iPad doesn't have enough store to download the software unless, as it says, I connect it to the compute). But when I connect it to the Mac, it flickers in and out of charge every second or so -- beeping as it does so. The iPad charges normally with a wall socket, so it doesn't appear to be a dust or dirt problem with the iPad's charging port. And my USB sockets are working on my MacBook as I can plug in peripherals (e.g., external camera) and they work just fine.

Moreover, I have gotten a message -- when, I guess, the Mac has managed to recognize that the iPad is, however briefly, connected to it -- that my iPad won't connect to the Mac because it needs new software...which I can get by connecting to the Mac...which I can't do.

Any idea what I can do? Thank you!

Your iPad appearing and disappearing when attempting to connect with your Mac is symptomatic of your iPad attempting to negotiate its power needs. Each time the iPad attempts to draw power, the USB connection is interrupted. If you are able, try using a different USB port on your computer - and/or attempt connection via a powered USB hub.

Be aware that most computer USB ports cannot source sufficient power to charge an iPad. Most models of iPad require at least 12W (i.e., 2.4A @5V) to reliably charge - whereas computer USB ports, unless explicitly designed for charging, are limited to 0.5A @5V (2.5W) or 1.0A @5V (5W).

Before attempting to update or connect to your Mac, ensure that your iPad is fully charged.

When constrained by available free-space, “Offloading” Apps can be a helpful method of creating temporary space for the software update.

You should note that for your iPad to install an available update, the iPad battery must be charged to at least 50% capacity - and/or be connected to its Power Adapter.

Thanks -- that's helpful. The iPad is in fact fully charged. Will definitely try offloading apps! Still -- any further advice on what might be keeping the iPad from connecting?
