Wanting to buy a current Imac now which has USB-a My hesitation is in looking way ahead in the future, and lets say I purchase a new maching now (which I would like to), which will havea USB-a port, and then lets say I get a iphone 8 which maybe will have a USB-c plug, or a future Ipad with a c plug, then what? I have been scouring the internet last couple of days, trying to see if there was such a thing as a male a plug transistion to a c plug female. I did find a couple, but the discussing was that USB-c protocol will not accept such a routing c to a to machine, and perhaps if using it could damage components of the computer. I hope this is clear as mud. I would appreciate any comments. Thanks!
