I am aware the Big Sur is currently in beta. However, still wanted to share an heads up for anyone looking to update and for the folks at Nvidia.
Thanks, we will look into this.
Same issue for Nsight Compute 2020.2.1 and MacOS Big Sur V11.0.1
Same issue for Nsight Compute 2020.2.1 and macOS Big Sur V11.0.1 with Apple Silicon M1.
Nsight Compute is not yet fully compatible with MacOS Big Sur. Full support for this will likely be added in a future version. In the meantime, you can try setting the environment variable QT_MAC_WANTS_LAYER=1 beforehand. I recommend setting it in a terminal window, and then launching Nsight Compute from the same window.
/Applications/NVIDIA\ Nsight\ Compute.app/Contents/MacOS/ncu-ui
then enjoy nsight on mac.
