What is libwidevinecdm.dylib on macbook? I got a pop-up while trying to watch netlflix.

I had a pop-up saying "libwidevinecdm.dylib" wasn't downloaded from the app store when I tried to use netflix while on google chrome. it gave the option of "Ok" or "Show in Finder". I tried googling it to understand it, couldn't find much except for possibly having a relation to streaming videos. There was a google link saying something else with a similar name was malware, so I panicked, deleted it on Finder, then realized it was something different. But after deleting it Netflix and HBO Max didn't work. I updated my software, video streaming services work again, and I never got the pop up again, but I am concerned about it still. Does anyone have a clear answer/understanding or am I diving way too deep into this?

Wikipedia claims that "Widevine" is a Google DRM system. If this "libwidevinecdm.dylib" is related to that, then it is presumably there to restrict how you access streaming content.


The article mentions a "content decryption module" which may be where the "cdm" part of the library name comes from. The name "libwidevinecdm.dylib" would then translate as "a dynamic library containing the Widevine content decryption module" – or something to that effect.
