I have a MacBook Air where someone attempted to install this version of bash over MacOS's native one unknowingly. I attempted to fix this by removing the files created by the installer (the readme was clear about it).
This version was causing error because it's compiled for PowerPC, so I immediately deleted it. Now I'm lacking Bash.
I'd use my system install disk to restore it, but I'm on an MBA and I'm not sure how to proceed from here. Any help is appreciated.
