Mac notifications do not work

[PfisterFactor]

I tried running the example at https://github.com/hoodie/notify-rust/blob/main/examples/mac.rs.
However I get no notification, the program just runs and closes. The notification center doesn't have anything either.

I am running on a M1 Macbook Pro (14-inch, 2021) on MacOS Monterey.
Compiling with Rust 1.58.0 stable-aarch64-apple-darwin. stable-x86_64-apple-darwin produces the same results.

This seems to be an issue with mac-notification-sys, as I don't get a notification even when using that crate directly. I've posted an issue there: h4llow3En/mac-notification-sys#33 (comment)

I know this issue is a bit old, but I investigated this last night and the problem is at least partially caused by where the binary is run from.

The daemon that handles notifications in macOS is called usernoted. When trying to generate notifications from my binary, usernoted threw errors about failing to read my binary (these errors show up in Console.app). I'm not sure why but my guess is because there is something it wants to check about the signature.

I develop in a subfolder of my documents which is a protected directory. Fetching the entitlements of usernoted:

    </dict>
</plist>

None of which grant it permission to access my documents. So I tried running my binary from /tmp and notifications started being sent correctly. This should also extend to /usr/local/bin/ as that is also not a macOS protected directory (other than normal unix permission).

Hope this helps people in the future.

Once the binary is placed in the /Application directory it works just fine as well. This issue will cause problems only during development of software, since you'd have to move the binary to directories that usernoted has access to.

What're the list of valid paths on macos then? This lib seems kind of useless if mac isn't easily supported.

I can't reproduce the issue on an M2 mac. Using version v4.8.0.

@mitjans that's why the issue is open for so long, it's a bit of a heisenbug.
