In the Mojave 10.14.5 update, Apple broke reliable SMB file sharing. Organizations found that the SMB service would stop responding after a few hours of uptime. Apple addressed this problem in 10.14.6.
Apple has another SMB problem. In this case, I’m talking about Small and Medium-sized Businesses. Apple has gradually been moving away from server technologies that small businesses rely on. File sharing is one of these critical services. It’s surprising that Apple performed little or no QA on such a basic service for 10.14.5. With the recent simplification (to put it mildly) of the macOS Server product, Apple is sending a strong message that it wants to get out of the on-premises service business. I would argue that there’s a limit to how far it can go in this business endeavor. There are legitimate reasons why businesses want locally-hosted services, such as performance and security.
Apple’s timeline for addressing its SMB problem is completely unacceptable. Here are the release dates:
10.14.5 – May 13, 2019
10.14.6 – July 22, 2019
Companies that use macOS file sharing had to resort to rolling back their OS or using AFP. I believe that any other mainstream operating system would have been fixed in a few days given a major failure of basic functionality. Apple’s timeline speaks volumes about how it values its SMB customers.
