I can't seem to change the permissions (let alone delete) anything in directories like
/usr/local (which I should be). My research has indicated that it's due to OSX automatically setting everything to be immutable. I was able to work through my problem by booting into single-user mode and remounting the partition with
-uw. From there I was able to use
chflags to remove the immutability.
However, I would REALLY love to not have to do this every time. Is there a way I can disable immutability globally across the system? Is there a reason I shouldn't?
