Hi,
While I don't have the flip 5, my s23 ultra hasn't received the new update yet either on OTA or smart switch (from the UK), I bought the phone a few days ago from an online retailer (not via a carrier and I'm not in the beta scheme)
I spoke to Samsung support and they told me the updates come in batches, similarly I have read reports depending on device region your carrier may be holding the update until they are ready to send it out OTA, maybe ask them for an ETA?
abit disappointing coming from an iPhone where the updates come out universally. I do hope I receive the update soon, especially since I have read reports that all s23 devices should have the update by now.
I have read there is away to update the firmware manually without smart switch however I believe it's tailored to more advance users and I personally am not sure I want to mess about with all of that, especially since the phone is brand new and I don't want to lose any data.
Re your question about the MacBook, perhaps you could try getting an adapter or buying another cable that supports data transfer online?
Apologies this doesn't answer your question directly but I hope it gives some more context from my experience dealing with a similar issue, I guess it's just wait and hope for the time being
😞
