Apple distributed to developers the fourth beta version of MacOS Sequoia 15.5

Apple released the fourth beta-version of the MacOS Sequoia 15.5 for developers. This was another step towards improving the operating system, represented last fall.

According to the announcement, the update identified by the assembly number 24f5068b became available on April 28, 2025 after the release of the third beta version in the previous week, writes Xrust. This beta cycle signals that Apple is focused on increasing user experience using gradual improvements, although specific details about new functions are limited.

The fourth beta version of the MacOS Sequoia 15.5 is primarily a release focused on developers aimed at eliminating errors and optimizing performance. Macrumors reports that no major additional functions were disclosed, which suggests that Apple gives the priority of stability, not catchy updates.

Journalists reflect on possible innovations. They write that the beta version will most likely be based on the main functions of MacOS Sequoia, such as the iPhone Mirroring, the autonomous Passwords app and the improved windows. They were presented at the launch of MacOS Sequoia in September 2024.

Update 15.5 can improve these tools, increasing the reliability for users who rely on seamless integration of iPhone-MAC or optimized password control. For example, the iPhone Mirroring allows users to manage their iPhone directly from their Mac, which is good for multitask users who want to control notifications without switching devices.
