I cannot import the module on my Mac m1 Big Sur.
This is the error I get.

Any news? I have the same problem with Mac OS Monterey (M1 Pro chip)

[anthonyaoun23]

Me as well, on a macbook pro 2015 Mac OS Monterey. No luck finding a fix yet, but same exact error.

[Pedro-Beirao]

It was working fine yesterday, but I decided to upgrade from 1.7.3 to 1.7.4, and not I get this error
Tried downgrading, but the problem doesnt go away.

MacOS Monterey - M1 MacBook pro

[Pedro-Beirao]

I think the problem is that pyobjc (https://github.com/ronaldoussoren/pyobjc) was updated a few days ago.
I will write back if I get it to work

Thanks @Pedro-Beirao! The problem is pyojc I downgraded to 7.3 and seems to work

[Pedro-Beirao]

Downgrading pyobjc to 7.3 also worked for me

[moses-palmer]

Thank you for your report.

I can reproduce this on a non-M1 mac, and it seems to be caused by changes to pyobjc. I hade made a small change and pushed the fix to master.

After downgrading pyobjc to 7.3, I get the below error;

  File "/Users/xxxxxxxxx/xxxx/xxxxx/lib/python3.8/site-packages/HIServices/init.py", line 11, in
    from HIServices import _metadata, _HIServices
RuntimeError: Wrong version of PyObjC C API (got 21, expected 22)

Has anyone else seen this / does any have a solution?

Are there modules with dependencies on PyObjC that also require downgrading?

Thanks,
Mark

[moses-palmer]

Please try the updated version of pynput instead; install from the master branch.

[markthompson94]

Do you know when we might be able to expect the fix included in a PyPi release?

Thanks,
Mark

[willwade]

Just to save anyone else the google:

pip install --upgrade pyobjc==7.3

Fixes this

[JeremyKeusters]

In case anyone still bumps into this, simply upgrading to pynput==1.7.6 does the trick now.
