System Information
Operating system: MacOs 11.2
Graphics card: AMD Radeon Pro 5500M 8 GB

Blender Version
Broken: MacOs 2.93
Worked: 2.92 and Win10 2.93

Short description of error
Addon Rigify won't load with 2.93 MacOs version.
Exact steps for others to reproduce the error
Run import binascii in Blender.

Or

Python: Traceback (most recent call last):

Win10 version works fine.
Thanks!

Ok I found a workaround. It's a Mac security issue.
When I disable the Mac's SIP (System Integrity Protection), I can load the Addon without any errors and everything works as expected.
I have no clue how to solve this at a Blender (Rigify?) level. Can anyone help? I'm not sure it's a good idea to lower the system's security to be able to run an addon...

Nope sorry. The latest nightly gives me the same error (related to Python?). I have to disable the mac's SIP to access the addon...

The ID of libz seems correct.. so not sure why our library has a relative rpath ?

$ otool -L "/Users/ankitkumar/blender-build/lib/darwin/python/lib/python3.9/lib-dynload/binascii.cpython-39-darwin.so"

	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.250.1)

The hotfix is install_name_tool -change ... but would be nice to fix cmake builder somehow.

I think this is a side effect of c70eb30240
macOS Python libraries should either link statically against zlib with a patch like that of linux, or use the system installation of Zlib.
Still need to build python to see if removing that dependency and those flags helps this issue.

Or reuse the patch to see if Python stays happy with libz_pic.a.

@ankitm Thanks for merging my report. I was aware of this one here, but thought a more generalized phrasing would draw more attention to, what looks like a very pressing issue.
If you think it makes sense, maybe rename this one here to reflect that?
Anyway, thanks for the fix, hope it gets committed quickly!

Then it's not the same issue. Please file a new bug report, or search previous reports for something related.

have the libraries been committed yet?

Yes, and new Blender builds have been uploaded too. But again, yours is a different issue.

ok, will file a new bug report.

I followed #85801 (Any addon installation from zip will fail in Blender 2.93 (using Python 3.9.1)) to get to this (#85648). It appeared that similar bug reports were being lumped here. Sorry for my confusion.
