I have a OSX vm (all stock, no mods of hacks). Everything works. I upgraded to a 16-core cpu (i7-7820X) and if I set more than 8 CPUs for my osx vm then it won't start.
With current release 5.1.x it always crashes on start, with 5.2.0 BETA it also crashes the same way, but if I try a few times eventually it starts up and inside my osx vm I see all assigned cores (all 16).

Post the guests log file ( as an attachment ). Right click on the guest in the Main Manager then click show log. Save and post as an attachment. Compress if it is too large to post.
Re: Cannot start osx vm with more than 8 CPUs
These are the logs. Just before I took them I had that crash when I tried to restart the vm (by clicking restart from inside of osx). When vbox crashed I got that messagebox with access to 0000000..00040 or something like that, Basically it's long list of zeros with some small number at the end.

You do not have an OSX Host, you have a Windows Host, and unfortunately OSX guests are only supported on Apple hardware (which you do not have). See: Important notice regarding Mac OS X as Guest.VirtualBox VM 5.2.0_BETA2 r117563 win.amd64 (Aug 15 2017 16:17:28) release log 00:00:01.145707 DMI Product Name: MS-7B06 00:00:01.147876 Executable: C:\Program Files\Oracle\VirtualBox\VirtualBox.exe
