MacOS Sequoia 15 Slow / Lagging? How to fix it

May 17, 2025 by Catalina OS

Is your Mac lagging or freezing while running macOS 15 Sequoia? Have you noticed it slowing down or behaving inconsistently since updating? Today, we’ll look into the latest version of macOS—macOS 15 Sequoia—and explore why it might be slowing down your system.

In that case, disabling some of the newer features could help improve performance. However, if your Mac is supported and you’re still facing slowdowns, don’t worry—there are several steps you can take to troubleshoot and speed things up.
