When i try to install adobe flash player it's failed. I'm on mac. It's written on my consol : sudo: brunocuenoud : TTY=unknown ; PWD=/ ; USER=brunocuenoud ; COMMAND=/usr/bin/open http://get.adobe.com/flashplayer/completion/aih/?exitcode=1&type=install
So i install mavrick then it's worked. I don't know why. But i found a lot of ACL on my computer and it's juste impossible to repare them. Maybe it's that because the first time on my consol it was written someting like : permission denied to write in library com.adobe.installer. And I see on forums that's lot of people had this kind of problem (ACL).
