tried uninstall/reinstall, disable/enable SIP, but didn't help. Any clue pls?

1. Reboot.
2. Download the latest release, or the latest test build (https://www.virtualbox.org/wiki/Testbuilds), if you don't already have them.
3. Mount the DMG from the previous step. Run "VirtualBox_Uninstall.tool". Make sure there are no error messages. If there are, please post them, exactly as they appear.
4. Reboot.
5. Mount the DMG from the previous steps. Double-click the "VirtualBox.pkg". As soon as you start the installation, press Cmd+L to show the log. Select "Show All Logs" from the drop-down menu. Before the last step of the installation (Done), click the "Save" in the log window. ZIP and attach that file.
6. Start VirtualBox. If it crashes, open "Console.app" and look at "~/Library/Logs". Is there a VirtualBox related log with the current date/time? ZIP and attach that file as well.

Thanks socratis, installer log attached. There was no error reported in console during uninstall, or starting up. but it still crashed with the same error reported.

[socratis]

Your installer log looks fine.
You need to find the crash log.

[chenchen]

how can I find the crashlog please?

[papi leoo]

I'm having the same problem! I have no idea how to find the crashlog

[socratis]

Post the output of the following commands entered in /Applications/Utilities/Terminal.app:

• 
  ls -ale@ /
  ls -ale@ /Applications
  ls -ale@ /Applications/VirtualBox
  ls -ale@ /private/tmp
