Thanks for software... I wonder how come Apple does not produce a very small OS X security update will just put relative .pkg receipts to do it with disk utility -repair permissions- and do this particular action at first install.

I know Input Managers will be locked for end user installation but same companies using the Input Managers can release a minor update requiring their application to be installed with admin rights.

I suspect even if it is needed.

Don't do the

sudo chflags schg

command. You need to boot into single user mode to undo it

(with sudo chflags noschg)

I believe you need to issue commands of the sort

sudo chflags uchg /Library/InputManagers /Users/*/Library/InputManagers
sudo chflags schg /Library/InputManagers /Users/*/Library/InputManagers

after that,

touch ~/Library/InputManagers/foobar
touch: /Users/wgscott/Library/InputManagers/foobar: Operation not permitted

man chflags for more info
