According to various critics and hardware reviewers, the 16-inch MacBook Pro pretty much checks all the right boxes and addresses the complaints that were rife with previous-generation models. However, that doesn’t mean users weren’t experiencing some problems.

Some time ago, owners of the premium portable Mac stated that their machine was giving out a ‘popping’ sound when running a media or video editing application such as VLC, After Effects or Premiere Pro. Apple later recognized the issue as one related to software and stated that a future update would help address this issue. Fast forward to today, one user reports that the latest macOS update has fixed the problem.
