I'm trying to delete the file /System/Library/SystemMigration/History/Migration-50EF6388-7D0F-42FD-B946-38F4A6A88D0D/QuarantineRoot/Library/StagedExtensions/Library/Extensions/Soundflower.kext. I've seen and followed instructions for doing so with a sudo command in Terminal, but that's not working for me. I think I may have the syntax wrong. I'd appreciate someone showing me the correct syntax for the kernel extension removal command. Thanks.
