macOS 15 Sequoia: Network problems and connection interruptions cause frustration | Message

After installing macOS 15 Sequoia, many users have encountered problems, particularly with regard to the Internet connection. Common complaints concern slow or incorrect loading of websites, with browsers such as Safari, Chrome and Firefox being equally affected. Users report certificate errors and glitches that occur particularly on websites with HTTPS encryption. While the problems were initially attributed to browser updates, it turns out that they occur regardless of the browser software used.

Extensive problem
It quickly became clear that the fault must lie in the network configuration, and for some users, the connection problems were made worse by programs such as “ESET” and “Little Snitch”. They report that these tools no longer work properly or are even blocked completely after the update. The macOS Sequoia firewall appears to be a major cause of the problem. These malfunctions create a vulnerability, especially for those who rely on this program to monitor incoming and outgoing traffic.

Network security at risk
The incompatibilities affect not only individual users, but also companies that rely on comprehensive network security solutions. This could lead to important security updates or other protective measures being bypassed, potentially leading to data breaches. Experts recommend that macOS Sequoia 15 should only be installed after a patch has been released. The software security company CrowdStrike has sent a “Tech Alert” to its customers and initially advises against installing macOS 15 Sequoia.

Unstable Wi-Fi connection
Slow or unreliable Wi-Fi connections, especially in networks with multiple devices, are also among the bugs mentioned. Apple has now confirmed the error and is working on a fix, but it is still a long way off. The company has announced that an update will soon resolve the most common problems. Until then, installing macOS Sequoia 15 is not recommended, especially for business-critical systems that rely on a stable network connection.
