The reason I ask is that about 2 months ago I gave my sister in law my iMac from 2015 because I never used it and felt that owning a computer is no longer needed. Turns out my assumption was wrong. I have needed a PC twice so I can hook up my devices to iTunes to get them in working order. Is anyone aware of any kind of workaround the use of a computer to restore idevices? If not, would it make sense to get a super cheap laptop to avoid the inconvenience of needing to run to the apple store every time something goes wrong?
