In this article we will figure out how to fix if your favorite browser began to lag at the most inopportune moment. There are several ways.

- In the window that appears, select the Updates tab and install any version of macOS or Safari (if, of course, it is available);
- Most likely, after installing the update, the problem with Safari will be solved.
