Hi, I was trying to run mono_euroc example on my device (MacOS 11.0.1) and the command crashes. I have mentioned the details below.

Command executed -

./Examples/Monocular/mono_euroc ./Vocabulary/ORBvoc.txt ./Examples/Monocular/EuRoC.yaml ./Datasets/MH01 ./Examples/Monocular/EuRoC_TimeStamps/MH01.txt dataset-MH01_mono

Output -

file name: dataset-MH01_mono

Same issue here. I am on MacOS Monterey with M1 CPU. Have you solved it ?
