VB 6.0.2 asserts while starting a macOS VM (#18362)

ModEdit; related ticket: #18362: VirtualBox 6.0.2 assertion failed while starting a macOS VM

My physical computer is a Mac Mini running macOS 10.13.6 and VirtualBox 5.2.2. Among several VMs I have, one is a macOS 10.10.

Today I tried to upgrade VirtualBox to 6.0.2, including the extpack, but when I tried to start the macOS VM, I got a meesage box with an error and the session did not start.

Checking the log, the only lines that seem to be related to VirtualBox are:

I removed 6.0.2, reinstalled 5.2.22 and the same macOS VM started normally, so at least 6.x did not damage it.

My understanding of the log lines is that this new version of VirtualBox running on macOS has a problem and an assert is triggered.

If this is not the right place to report such problems, please advice where to do it.

No, this is the perfect place to do it! ;)

From the error message that you got:
... Class FIFinderSyncExtensionHost is implemented in both ... and ... /FileProvider.framework
/OverrideBundles/FinderSyncCollaborationFileProviderOverride.bundle/Contents/MacOS/...
One of the two will be used. Which one is undefined.
I don't know about you, but I don't like the sound of things being "overridden"... This is *not* a virgin OSX, is it? Sounds like you've seriously messed with it, at the system level, no? Could you shine some light on the situation?

Well, OSX is as 'virgin' as Apple managed to keep it so.

I treat it as a production server, and I don't run anything directly on it, but in the virtual machines. I kept a log of all maintenance operations, I can provide dates and details; it was re-installed in Jan 2018 as 10.13.4 + server 5.6 + VirtualBox 5.2.8 and later updated to 10.13.5 and 10.13.6, and VirtualBox to 5.2.16 and 5.2.22.

Except some hdiutil to manage the backup volumes, there were no other operations performed.

I would not consider the system to be seriously messed up; on the contrary.

Please note that VirtualBox 5.2.22 is perfectly happy with the system, the problem occured when I tried to upgrade to 6.0.2. I would start from the reason behind the assert. Is it a real problem?

As for the two bundles, it looks like a known Apple problem:

Is there anything I can do to help with fixing this bug? Is there a bugzilla, or similar, to register it?
