Could this also happen with Adobe Reader DC or Adobe Flash Player. We got a couple of machines last week which booted into recovery mode because the /Applications or /System folder was completely deleted. We are using Adobe Reader DC and Adobe Flash Player update scripts. Does anybody had the same behaviour?

@donmontalvo He knows. A few of us reached out to him on the #adobe-installs channel on the [macadmins.org](macadmins.org) Slack yesterday.

The update has been pulled & a fixed version expected in the coming days.

@anverhousseini It's only via CCDA & only when installing I think via that.

Also, it's affecting hidden folders at the root of the HD. Not others.

@bentoms We still don't know what could cause such a big issue. The timing would be perfect ;)

Creative Cloud Desktop 3.5.1.209 addresses file deletion bug.

I went digging for an outgoing tweet/formal message, but Twitter replies from @AdobeCare was the best I could find at the moment.

3.5.1.209: Fixed an issue in the Creative Cloud for desktop app for Mac where in some scenarios the application may incorrectly remove files with user writeable permissions from the system root directory.
