Using SageMath-9.6 (v1.4.2 for arm64) under macOS 12.5.1, in a new notebook I evaluated:

Manifold(2, 'M')

and get error:

NameError Traceback (most recent call last) /var/folders/r2/v_ly_rjj6_v1qpzx4kqy_mqr0000gn/T/ipykernel_37595/1178276850.py in <module> ----> 1 Manifold(2, 'M')

NameError: name 'Manifold' is not defined

According to the docs at https://sagemanifolds.obspm.fr/downlo..., "all SageManifolds code is included in SageMath..."

What's wrong?

Maybe you created the notebook with kernel "Python" not kernel "SageMath"? If so, you can change the kernel in the menu. If so, I also advise you to do the "User Interface Tour" from the help menu.
