Hello @xinbao

Which chip do you used? Please take a video or screenshots show your detail steps, that I will reproduce it on my side.

Can you tell whether your computer is x86 or arm architecture? Version 1.5.0 does not support Apple computers with M core. BTW, please check the document on the prerequisites of MacOS.

Thanks
