I thought in terms of switching USB plugs on the laptop. Since the phone was still charging with that fabric chord, which I would not have bought if the seller did not include it, I did not think the chord caused the problem. At Genius Bar, since the technician used a new chord to connect - and I had no other chord - I told him to dispose of the fabric one and sell me a new one. That outside material I do not like. I have seen it before for connecting instruments to amplifiers. Due to performance problems, I have to plan on replacing this Mac Monterey over the next year. It displays beach balling, kernel panic errors, just enough RAM and HD space for this OS. Thank you to all. I am going to have to put up with this system for a while. At Genius Bar they said the laptop was going through old age; and they could not make changes to the storage.
