InReach mini without USB capability on computer

I just purchased an InReach mini. Attempting to set up for days now. Synchronizing. Tech advice says “when you are sitting at your computer….”. The last time I sat at a computer, George Bush was president. As an airline pilot, I live out of a suitcase. I carry an iPhone, company issued iPad, and occasionally a MacBook Air. Thankfully I have not needed a desktop in over two decades now. It’s starting to seem like this unit will not be usable unless I start shopping for an old fashion computer with USB ports. I’m not going to do that. Is this unit really unusable now?
