I'm running OSX 10.11 (El Capitan), DP1. I'm attempting to install the Fujitsu ScanSnap software. The installer proceeds well, but then appears to hang towards the end, at "Running package scripts": I have left it here for around 20 minutes, no change. Running lsof | grep Installer, I get: https://gist.github.com/victorhooi/caaed31b976d15a51a00 Running lsof a few times, the output doesn't appear to change, so it appears to be stuck at wherever this is. Also, even if I Force Quit the installer, OSX doesn't even let me restart the machine after this - I need to send a SIG9 to "installd". Does anybody have any ideas on how to work out why the above process is stuck? Or any possible workarounds/fixes?
