I just shared a photo using the sequence you described from Android -> MacOS.
Contrary to my sibling commenters, it did just work. A prompt appeared on MacOS asking if I wanted to accept the connection request, then asking if I wanted to accept a filee. I agreed, a download progress bar appeared until it was finished, and when it was done, the file was in the Downloads folder.
Wow, it was incredibly slow, though. Transfer rate ~50kB/s, about 500x slower than uploading the file to a cloud server somewhere and downloading it again. 2000x slower than local Wifi. Distance between devices: about 60cm. Time to transfer 1 photo: 10 seconds, after starting the download.
The Android UI was unhelpful for finding the Bluetooth option to share to. The Share icon showed 5 share methods (none of them Bluetooth, one of them "Quick Share" to "nearby Galaxy devices", it's even more specific than Android-only), plus 5 contacts-with-methods (none of them useful: SMS and WhatsApp, and I don't even have WhatsApp activated on this phone), plus a different kind of button for "Nearby Share" (something to do with nearby people in your Contacts, which doesn't explain how it does that so I assume some cloud service I'd rather not use). Finding "Bluetooth" involved some hardly discoverable horizontal scrolling with no visual affordance, using a different UI than the share options listed from other apps.
But it did work, extremely slowly.
It's not obvious, but some of the other share options use Bluetooth to set up the connection then Wifi to transfer the files, perhaps about ~2000x faster. Some supposedly use local Wifi alone, no Bluetooth required. Unfortunately I've never had success with any of them, so I can't confirm if any of them actually work as advertised. A few years ago I spent nearly an hour trying to all the different methods on the phone I had, to send a collection of photos from Android to MacOS without using an internet service, and nothing worked. Each built-in sharing method failed in some way, and standard Bluetooth file transfer was too slow. In the end I gave up and transferred just a few of the photos the slow way. It is striking (and absurd) that cloud services run much faster than local transfer - when both devices have access to a usable internet connection.
