macOS 12.3 removes python 2.7

Source: https://macmule.com/2022/01/29/macos-monterey-12-3-will-remove-python-2-7-usr-bin-python/

Given that python 2.7 will no longer be part of the system from that release onwards, the following error will appear:

/usr/local/bin/display_manager.py: bad interpreter: /usr/bin/python: no such file or directory

As a workaround, is it possible to specify the location of python 2.7 to use?

Hi @ptrkstr:

Thanks for the feedback and opening an issue. But, TBH, our team is very busy with other projects and we will need dedicate time, attention & testing to the migration of the display_manager script to python 3.

Will will keep adding it to our to-do's and get to it as soon as we are able.

In the interim, you can implement @whyisjake suggestion to install python 2.7 or use other options like relocatable-python: A tool for building standalone relocatable Python.framework bundles.

Hi, having the same issue here. Tried @whyisjake's approach but can't seem to get it to work. Could you please add some instructions on how to get this to work again?

Hi @uurazzle, that workaround looks good, I appreciate the reply 🙏

Hi!

Tried the relocatable-python workaround but am still getting errors. Any ideas?

thta@m1air-01 ~ % /usr/local/bin/display_manager.py help Traceback (most recent call last): File "/usr/local/bin/display_manager.py", line 27, in <module> from display_manager_lib import * # The Display Manager Library File "/usr/local/bin/display_manager_lib.py", line 27, in <module> import objc # access Objective-C functions and variables ModuleNotFoundError: No module named 'objc'

Tried manually installing objc but can't seem to get it to work.

hi folks, is there an update somewhere on horizon that wouldn't need to require the workaround?

Hi, @filipruisl:

Sorry, we haven't had the bandwidth to focus on this project, but it is on our to-do's when we have time and can fit it into our priorities.

Looks like the code has been update for Python3 (much appreciated!). However, the ReadMe file still references Python 2.7.

It seems the interpreter location and the install location of the lib is incorrect for this Ventura.

I was able to get this running on MacOS 13.2 from the installer without relocatable python by:

1. Installing Python 2.7 from python.org installer.
2. Change the interpreter (first line) of /usr/local/bin/display_manager.py and /Library/Python/2.7/site-packages/display_manager_lib.py to #!/usr/local/bin/python2.7
3. cp /Library/Python/2.7/site-packages/display_manager_lib.py /Library/Frameworks/Python.framework/Versions/2.7/lib/
4. pip2.7 install pyobjc

It worked after that. May need 'sudo' to copy to those dirs.

@uurazzle I can see the code has been updated to python3. Can you guide to use it with python3?
