When using Personal Hotspot from a MacBook, macOS automatically drops the Wi-Fi connection to the iPhone whenever the phone loses cell service. Is there a way to keep the Mac connected so it reconnects automatically when service returns?

There is no built-in macOS setting to disable automatic disconnection from an iPhone Personal Hotspot when the iPhone temporarily loses cellular service. macOS sometimes disconnects or deprioritizes hotspot connections that no longer have upstream internet access, which can require the connection to be re-established after service returns.
Try one of these workarounds:
Use Instant Hotspot. On the Mac, click the Wi-Fi icon in the menu bar and select the iPhone under Personal Hotspot. Instant Hotspot uses Bluetooth for discovery and coordination while carrying traffic over Wi-Fi. Unlike a standard hotspot connection, temporary cellular signal loss does not always cause the hotspot session itself to fully disconnect. In some cases, the Mac remains associated with the iPhone and traffic resumes automatically once cellular service returns, without requiring manual reconnection.
Tether over USB. Connect the iPhone to the MacBook with a USB-C (or Lightning-to-USB) cable, then on the Mac open System Settings > Network and confirm the iPhone USB interface is enabled and at the top of the service order. USB tethering is less likely to disconnect when cell service drops; the interface stays up and traffic resumes the moment the iPhone regains signal. This is the most reliable option on trains and in tunnels.
For reference, see Apple's support article "Set up Personal Hotspot on your iPhone" for the supported connection methods.
