Can't install the latest and 5.1 versions on MacOs

[eignatik]

I faced a little trouble. I tried to install VB on my Mac. And every time during the installation I get the error "The installation failed" whatever version I tried to install. Never faced that before.

1. There is no 5.1 version of VirtualBox. There is 5.1.0, up to 5.1.36, in increments of "2". Please use the exact VirtualBox version. Small details make all the difference.

2. You didn't mention your OSX version, but I'm willing to bet it's a 10.13.x. Is that correct?

3. If you're using 10.13.x, did you see a warning that you should head to the System Preferences » Security page and explicitly allow Oracle's VirtualBox to install kernel extensions (kext)? Similar to the one described in Apple's Technical Note 2459: ​Apple Technical Note TN2459 - User-Approved Kernel Extension Loading?

4. Did or didn't see that dialog, go in any event to the Security in System Preferences and do approve of Oracle. Then call Apple and yell at them, as loud as possible for their half-baked, misimplemented, completely botched "security" solution (to a problem that didn't exist).

May I suggest something? It's usually better and faster, if issues like this one (configuration, question) get first addressed in the ​VirtualBox forums. More than 95% of the issues are resolved over there, which keeps the developers focusing on the bug fixes and enhancements, and there is no need for another ticket to keep track of. For example, yours is most probably not a bug and someone from the developers has to deal with it and close it as "Invalid".

So, if the above procedure doesn't resolve your problem, please open a new thread in the ​VirtualBox on Mac OS X Hosts section of the forums. Please be sure to mention that you came from the bug tracker and include the ticket number.

And finally and most importantly; do NOT forget to call Apple and let them have it. VirtualBox is not the only one having to face this problem. A lot of software has been impacted. It was really bad when 10.13.0 came out, now it seems that they have addressed the key issues in recent updates, but we're still see the issue once a week or so. Before the fixes it wasn't 1 complaint in 7 days, it was 7 complaints in 1 day... ;)

Thanks for reply. Yes, I'm very sorry, I was in a hurry. I tried 5.1.36 and 5.2.10 VirtualBox versions to install. MacOS 10.13.4

So, I believe that a problem is exactly with these kernel extension things. But the point is that in Settings > Security page the "allow" Oracle's VirtualBox doesn't even appear. Whatever I did. I tried to use uninstall tool, I even turned off this kind of a security check via a terminal. But I still get this error.

And the funniest thing that my wife just installed VB on her MacBook with the same OS and the same VB version and this "allow" option did appear.

It seems I need to find out what is wrong with my Mac, why this option in security doesn't appear at all.

Thanks for your respond. I will check all links you shared with me. Have a good day :)

Shut it down for more than 30 minutes. It has a tendency to ... reappear out of the blue!

And don't forget to "praise" Apple. In person. Go to a genius bar and lash out (not the poor guys working there) at their software/security department! :D

PS: There's no real "need" to quote the whole previous message verbatim. It adds to the length of the conversation unnecessarily... ;)
