macOS Mojave cannot get already set key passwords since v23.1.0

[atomiechen]

Describe the bug
On macOS Mojave (other macOS version not tested), the README demo steps fail:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFType bytes]: unrecognized selector sent to instance 0x101ed5d10'

when calling keyring.get_password in python or keyring get in command line after setting a password. In system app Keychain I can confirm that the key password is set.

The problem disappears when downgrade to version 23.0.1 and shows up since version 23.1.0.

To Reproduce
Steps to reproduce the behavior: follow README demo steps

Expected behavior
The console log is as follows:

Environment

• OS: macOS Mojave 10.14.4

$ keyring --list-backends

Additional context
I encountered this when trying notion-scholar on my Macbook Pro before I realized that the cause is rooted here.

Update: after I upgrade my MacBook Pro to Monterey, the problem no longer exists.

There were several compatibility issues between Python and macOS and the ARM transition (which happened in Python 3.7/3.8).

As you can see in the changelog, v23.1.0 introduced one change as found in #519, where the API was updated.

Probably Mojave didn't have that API yet. My recommendation - if you're using an older version of macOS, you may need to use an older keyring.

Having the exact same issue with MacOS 12.5.1, Python 3.10.5 (and 3.9.13) on an ARM M1 Max.

Tried keyring 23.6.0 and 23.8.2.
Reverting to 23.0.1 is still a workaround.

Update: issue was due to compiling python through asdf/pyenv with outdated clang (bundled with llvm@11).
