Description

Bug stacktrace:

Im on a macOS system. Here's a partial stacktrace screenshot of the error I ran into
Image

Everything else in stack trace is custom library code and truncated for brevity

Potential bug site:

The issue is in:
https://github.com/fsspec/filesystem_spec/blob/961412dc83cb242728860f8637ab234485962f40/fsspec/spec.py#L568

Exception has occurred: AttributeError       (note: full exception trace is shown but execution is paused at: _run_module_as_main)
module 'posixpath' has no attribute 'sep'
  File "/path/to/my/venv/python/virtualenvs/base_lock/3.10.16/lib/python3.10/site-packages/fsspec/spec.py", line 563, in glob
    seps = (os.path.sep, os.path.altsep) if os.path.altsep else (os.path.sep,)

Research direction

Start in fsspec/spec.py at the glob method around line 563, where os.path.sep and os.path.altsep are accessed. Reproduce the macOS failure with the reported Python 3.10 environment and verify that glob no longer raises AttributeError for the path separator lookup.
