glfw window (mjcviewer) application not responding on macos

[shivanimall]

Hello,

I am on macos, I can successfully run robosuite, but unable to see mjcviewer.

referred to this to load on-screen: https://robosuite.ai/docs/modules/environments.html:

# create an environment to visualize on-screen
env = robosuite.make(
    "TwoArmLift",
    robots=["Sawyer", "Panda"],             # load a Sawyer robot and a Panda robot
    gripper_types="default",                # use default grippers per robot arm
    controller_configs=controller_config,   # each arm is controlled using OSC
    env_configuration="single-arm-opposed", # (two-arm envs only) arms face each other
    has_renderer=True,                      # on-screen rendering
    render_camera="frontview",              # visualize the "frontview" camera
    has_offscreen_renderer=False,           # no off-screen rendering
    control_freq=20,                        # 20 hz control for applied actions
    horizon=200,                            # each episode terminates after 200 steps
    use_object_obs=False,                   # no observations needed
    use_camera_obs=False,                   # no observations needed
)

To note, I have successfully opened igibson, mujoco and pybullet viewers. also, robosuite + pygame renderer worked.

Following is the output:

but robosuite + mjc_viewer does not -- window instance says application not responding on mac dock. Please let me know if you need further details, thanks for help!

Dear @shivanimall, it appears to me that this issue was not caused by robosuite, but some configurations of your system runtime. I can confirm that the mjc_viewer works fine on my macOS (I have Big Sur). I would suggest you search with the error message "ApplePersistenceIgnoreState: Existing state will not be touched." and see if you can find any online solutions that resolve your problem.

thanks @yukezhu! want to confirm that mujoco viewer w/ robosuite is now working.
