Macos opens Instruments when I press "Command" + "~"
Unfortunately when I have opened Chrome and I want to switch between its windows, ⌘` opens Instruments.

As Instruments is a part of Xcode, not Google Chrome, check the Chrome &gt; Services menu for a service assigned: ⌘`
You can change it in: System Preferences &gt; Keyboard &gt; Shortcuts &gt; Services
