Repetitive "macOS Detected" notification

Occasionally, Parallels Desktop gets stuck in a loop where it keeps showing a "macOS Detected - Click to install macOS" notification over and over again. I can turn off notifications to stop it, but I can see in the notification center that the time is always "now" which means it's continuing to issue that notification.

Does anyone else get this, or know what causes it?

I do have both Acronis True Image 2019 and Bitdefender Antivirus installed, which are probably the only really nonstandard things I have that might conflict with Parallels. I also have 24 virtual machines, which might be more than most people, but I only have one VM actually running when this is happening.

* macOS Mojava 10.14.1
* iMac Pro
* Parallels 14.1.0 (45387)
* Acronis True Image 2019 23.4.17000
* Bitdefender Antivirus 7.2.1.6

It happens every time when my AntiVirus scans DeveloperDiskImage.dmg from xCode. And there are a few!..

I'm not sure why PD needs to constantly watch disk access, isn't that going to cause performance issues, surely!? That's a bigger issue than the annoying pop up "macOS Detected"...

Parallels devs: Could you please provide us with the option to "DISABLE DISK ACCESS WATCH", I would be quite happy to manually create VM without getting prompted by PD whenever I download an O/S image to improve performance and save the annoying pop ups.

I had almost the same problem. Turned out that sometimes antivirus and Parallels have some troubles working together. It happens because an antivirus sometimes may mistake Parallel's processes for malware. In this case, to prevent the antivirus from blocking Parallels Desktop processes, you just need to make a full virus scan and add Parallel's processes, which usually start from prl or parallels to a trusted list.

Best regards, Nora

I doubt this is the case. It's more likely that Parallels watches file access constantly, and a file handle with an O/S image is opened, it then displays this silly message. When antivirus runs a full scan, it needs to open the file handles to scan the files, thus the message. I would be much happier if Parallels didn't watch my file access all the time, and an option for that be provided, but with the lack of their input, it appears that Parallels support doesn't frequent this forum much.

I sent a test report 325684916 on Nov 9, 2019
I sent you a new report now again 352187743.

You can replicate the issue yourself!!! Here are the steps:
install Xcode from appstore

then in finder, go to:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/DeviceSupport/13.1

copy DeveloperDiskImage.dmg onto your desktop.

Voi'la the pop up appears ("macOS detected; Click here to install macOS."). If you did these steps, you just simulated the same behaviour as when AntiVirus is scanning these very files.

Thanks a lot for the provided information. We've involved Parallels Engineering team in this case for the further issue investigation.

I, too, can confirm that the problem still exists with 16.1.0 (48950) - maybe even worse than before the update.
FWIW: I recently (30 Sep) installed CleanMyMac X, configured to provide "malware and threat protection"; I thought that this might be significant based on information from other reports on this topic. Also, for years I have run Intego VirusBarrier without any problems, but maybe that has changed. (I will try turning them off one by one to see if that "fixes" it.)
