I clean-installed Mavericks and now tried to install MacTex.
I tried 1. downloading the MacTeX.pkg from http://www.tug.org/mactex/index.html 2. downloading from mirrors [http://www.tug.org/mactex/mirrorpage.html] 3. using Safari 7 and Safari 5. 4. changing permissions and ownership [me: read & write, me: owner]
I always get: Installer: "The Installer is damaged. The Installer can’t open the package. There may be a problem with file ownership or permissions." Installer log: "Dec 3 14:42:24 Js-MacBook-Pro.local Installer: Install's runner tool is not properly configured as a setuid tool. Dec 3 14:42:24 Js-MacBook-Pro.local Installer: Unable to create InstallController"
None of the related threads could help me.
