Apple: Latest macOS Supplemental Update Patches Crackling Speaker and Kernel Panic Issues

macOS High Sierra title headline

Earlier this week, Apple released a minor update to the macOS High Sierra 10.13.6 platform, which may not be as minor as the release notes might have suggested.

Apple has clarified the latest software update for the desktop operating system, saying that the new software actually fixes two of the major issues that were plaguing the OS. If you’ll recall, Apple’s latest hardware, both the iMac Pro and the 2018 MacBook Pro, have been plagued by kernel panic issues (rumored to be courtesy of the T2 chip inside the models). In addition to that, some 2018 MacBook Pro owners have been plagued with a crackling speaker issue while listening to content from YouTube, Spotify, and other sources.

According to MacRumors, which received a response from Apple regarding the supplemental update released yesterday, the software patch addresses those issues directly. As noted in the original release, Apple reiterated in its statement that all users install the supplemental update on their MacBook Pro units.

The software update has only been around for a short time, but it appears that the fix is working for most when it comes to the crackling speaker issue. As noted in the original report, an Apple Support Communities visitor, “takashiyoshida”, published their own reaction following the update:

“This evening, I set the microphone and speaker’s sampling format to 44100 Hz and began playing back music on iTunes. Before the update, I would normally hear the noise in about an hour. I left my MacBook Pro to play music for about three hours and so far I am not hearing any noises.”

However, it appears some users are still hearing the issue when they watch/listen to content on YouTube.

The kernel panic issue appears to still be plaguing some folks, even after they’ve updated to the supplemental update. One user said, “Installed today’s update… and then it happened”, in regards to the kernel panic issue and updating to the new software.

Unfortunately, based on the anecdotal evidence so far, it does not appear that this supplemental update actually fixes the issues as well as Apple might have liked. If anything, this may be just one step in a series that Apple needs to take before fixing the issue completely.

Our Take

Both of these problems plaguing the latest-generation iMac Pro and the 2018 MacBook Pro are incredibly frustrating, so it would stand to reason that owners would want them fixed as soon as possible. Unfortunately for those who are still experiencing the problems even after updating to the newest supplemental update, the wait continues.
