The other day i had this message in my chrome settings: “your browser is managed by your organization”. well, it was actually in german language, so it’s more like this one:

starting with chrome version 73 this warning comes up if one or more of chromes built-in policies differ from the default settings.
so you google the problem and you may find some solutions … for windows! (gasp) — or you come across the ‘solution’ to simply suppress the message without fixing the real problem…
most of us are not part of a browser-managing organization. therefore it would be nice to see which policy elements are set. you can see them with the browser-internal url:
this should bring up something like this:

here we go again… wasn’t it months ago when you were fed up with that chrome cloud printing dialog?
cheesy google print dialog… … apple’s print dialog for real men ;-)
you wanted apples’ standard dialog window with chrome! you wanted back control!! you wanted reven… – whatever!
so you updated the policy above (DisablePrintPreview=true) and lived happily ever after since… until now: “your browser is being managed by someone else!” – you want to get rid of that message, for zarquon’s sake!
the thing is, when you set the policy element back to “false”, this still counts as a modified policy.
you can set the propery back with this command in a terminal window and restarting chrome:
defaults write com.google.Chrome DisablePrintPreview -bool false

…and guess what shows:

ok, so setting the property to “false” obviously leads nowhere. the trick is, to delete the property like this:
defaults delete com.google.Chrome DisablePrintPreview
et abracadabra: after a chrome restart your browser belongs to you again. no evil corp controlling whatever sleazy (or not) policies are set.
jokes aside: this method is a good way to see if this policy you deleted is actually the reason for the nefarious message. if the message persists after deleting the policy, there’s still another policy active.
