這是因為沒有權限打開createinstallmedia，修改權限即可:
swaedeMacBook-Pro:~ swae$ chmod +x /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia
修改完成權限后狱从，重置制作u盤啟動即可：
/Volumes/Install macOS Catalina/ is not a valid volume mount point.
swaedeMacBook-Pro:~ swae$ sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/Catalina/
Ready to start.
To continue we need to erase the volume at /Volumes/Catalina/.
If you wish to continue type (Y) then press return: Y
