I'd expect something like Cyberduck quality UI, as an example. The author should aim to mimic system UI in my opinion as closely as possible (or integrate inside Finder).
I also have a usb-c flash drive for copying as well.
Amazon has a great MTP app but it only works with Kindles.
Your mileage may vary.
I don't think using ADB is the right way to go about it. Normalizing elevated shell permissions just to copy files just feels like going the wrong way about it. Unless that's the only way to get decent Android file management done on Mac, of course.
Edit: I thought Apple supported MTP but I guess they never did? That's a weird limitation for an OS to have.
Clearly a Mac user should also have an iPhone, or face the repurcussions for using a non-Apple device.
But why does it matter? Does the app not work? I don't have a Mac, can't check.
A file manager better be rock solid, I don't want a bug to delete any files or do other shenanigans.
But that would apply to any app that deals with files like this one does.
This one is open source and we can run some code analysis on it, compile locally, etc. I am not well versed in security checks but I guess you get the idea.
As usual, it is low quality and has zero tests.
The README.md uses a ton of Emojis in the feature Setting.
100% AI.
And of course every commit is Co-Authored by Claude Code with excessive commit descriptions also created by Claude. Is this really something we want to see on Hacker News? I wouldn't trust such an application.
Nothing against AI coding but letting AI take the wheel 100% of the time and not even mention it (like he coded it himself) is very dishonest.
