A Doro 8-series Android phone and a Doro 2880-style flip phone are basically two different questions wearing the same title, and half the advice here only fits one of them. @luc1d_loop already flagged this, but I think it’s the whole ballgame, not a footnote. Figure out which one you have before you touch MacDroid or anything else, because the smartphone advice will just waste your evening if you’re holding a feature phone.
Here’s the bit people keep dancing around. A lot of the simpler Doro models don’t expose a clean MTP file system at all. You plug them in and macOS either shows nothing or shows some tiny partition with folders you didn’t ask for. On those phones no transfer app saves you, because there’s nothing sensible to mount. That’s where the microSD card reader route earns its keep, and honestly for a feature phone I’d skip USB entirely and go straight to pulling the card. Faster, fewer surprises, and you’re not fighting a phone that was never really designed to talk to a Mac.
If it is the Android Doro, then yeah, the earlier USB and MacDroid points hold up. The tool does the job Finder refuses to do, and I wouldn’t dismiss it. I’d just treat it as the thing you reach for after you’ve confirmed the phone shows a proper file-transfer mode, not before. Installing a manager app to troubleshoot a dead charge-only cable is a classic waste of time, and @owl1369 is right that dodgy cables cause more of these ‘phone won’t appear’ complaints than any software ever does.
One angle nobody’s mentioned: the Google account you set up on the Android Doro. If it’s already signed in, your camera photos may be quietly syncing to Google Photos anyway, and you can just grab them from the web on your Mac. No app, no cable, no card reader. Not great for a huge backlog, but for the ‘I took some pics and want them on my laptop’ case it’s the least fiddly thing going. Cloud gets a lot of grief in this thread for small jobs, and I get why, but for photos specifically it’s often already half done without you noticing.
So my rule would be simple. Feature phone, use the card reader. Android Doro with photos only, check if they’re already in the cloud. Android Doro where you need real two-way access to documents and downloads, that’s the one case where MacDroid or a similar MTP app actually earns the install. Copy first, verify it opens on the other end, keep the originals until you’re sure. The Doro’s file format support is the quiet killer here, so don’t assume a PDF that opens on your Mac will open on the phone.
