macOS Sonoma update fixes USB hubs, Java crashes, and more

macOS Sonoma 14.4 update breaks USB monitor hubs

Following iOS and iPadOS updates late last week, Apple has released a complementary update to macOS Sonoma with security updates and some big bug fixes.

It's still not fully clear what the update contains in its entirety. The patch notes displayed for a manual update mention the updates provide "important bug fixes and security updates," and that it is "recommended for all users."

The update notes also include a link to details of Apple's security releases. Monday's macOS update, and last week's iOS updates fix an arbitrary code execution flaw in CoreMedia, and a similarly exploitable flaw in WebRTC.

Monday's macOS Sonoma 14.4 update fixes a few problems. USB hubs in monitors weren't working properly under the prior update. Additionally, a bug in the 14.4 release caused Java processes to terminate unexpectedly.

Other users were seeing problems with printing. For some users, the update process removed the core CUPS software, leaving no way for the printer and Mac to interface. It's not yet clear if this has been fixed, and we will update this post as more information develops.

Alongside the macOS 14.4.1 update, Apple also released macOS 13.6.6. Update notes are similarly sparse. The macOS 14.4.1 update is build number 23E224, with the macOS 13.6.6 update holding build 22G630.
