Apple’s macOS Sequoia Update Causes Security Tool Failures For Enterprises

Apple released the stable version of macOS 15, also known as macOS Sequoia, to users on Monday. However, the current update has generated unforeseen problems, notably with third-party security solutions from businesses such as Microsoft and CrowdStrike. These issues raise worries about the security of businesses that rely significantly on Mac devices. 

According to concerns from users and tech forums, the macOS Sequoia update appears to be causing issues with network-based security products developed by Microsoft, CrowdStrike and SentinelOne. TechCrunch cited complaints from a Mac-focused Slack channel, where several users stated that their security software had ceased working properly after installing the update. These tools, which are frequently implemented in enterprise contexts, are crucial for ensuring cybersecurity and their failure might leave firms vulnerable.

Users on Reddit have raised similar issues, stating that security apps stopped working after the update. Some speculated that the problem stemmed from bugs in macOS Sequoia. One Reddit user commented that, despite Apple's developer builds having been accessible for some time, the absence of quick compatibility for these tools was ‘amazing,’ raising concerns about Apple's interaction with third-party security vendors. 

One CrowdStrike sales engineer commented on Slack that, despite the company's best efforts, their solutions will not be fully supported on macOS Sequoia from the start. It's unclear whether the tools have restored functionality after more debugging.

The impact of macOS Sequoia's problems appears to extend beyond security tools. A Reddit user stated that approximately 90 percent of the apps on their M1 Max-powered MacBook Pro were having problems. They also complained about Wi-Fi connectivity, alleging that even though their smartphone could connect to a hotspot, internet access was not working.

 Will Dormann, a security researcher, reported on Mastodon that he experienced DNS difficulties and firewall faults on his Mac computer after updating to Sequoia. Despite the mounting number of complaints, Apple has failed to publish a comment or set a schedule for correcting these concerns.
