1561731 - [10.15][Mac] libwidevinecdm.dylib can't be opened because it is from an unidentified developer

Status: RESOLVED DUPLICATE of bug 1558924

(Core :: Audio/Video: GMP, defect, P1)

Description

[Haik Aftandilian [:haik]]

Attachment: widevinecdm-error.png

When trying to watch Netflix on macOS 10.15 Beta 2 with Firefox, a GateKeeper dialog is displayed (see attachment) stating "libwidevinecdm.dylib can't be opened because it is from an unidentified developer" and then the CDM crashes. As a result, Netflix is not usable with Firefox on 10.15.

This was first reported on bug 1556733 comment 31.

Like bug 1556733, this might be due to the changes in 10.15 regarding launching quarantined applications. I'm looking into this.

See the Apple WWDC presentation about quarantine changes in 10.15:

After a change that disables quarantining of the downloaded CDM dylib, the CDM crash appears to be a EXC_BAD_INSTRUCTION crash in libdispatch.dylib`_firehose_task_buffer_init. More debugging needed.

Haik, watch out for the Widevine version changing in bug 1561693. It's on nightly as of about 3 hours ago.

Thanks for the heads up! I'll make sure I have that version and retest. Closing this bug as a dupe of 1558924.
