How to prevent Mac from changing the order of Desktops/Spaces

Question

You may have encountered a situation in which Mac changes the order of desktops based on some events like alerts on a program or a web page in browser.

How could I disable this logical change?

Note: I'm using El Capitan, but I had this problem since Mavericks.

Newer MacOS Ventura (v13)

System Settings > Desktop & Dock > Scroll down to Mission Control section > Uncheck Automatically rearrange Spaces based on most recent use

Older macOS (v12 and older)

System Preferences > Mission Control
Uncheck Automatically rearrange Spaces based on most recent use.

This will fix the order of all your regular Spaces - but not Fullscreen spaces, which always go to the right of existing numbered Spaces.

From comments: Note this cannot fix the Mac confusing which external screen is which. That's not user-controlled at all, & seems to occur mainly [though not always] when the external screens are identical.

Late note:
This echoes the behaviour of Cmd/Tab or equivalent in most operating systems, so could be considered a 'sensible' default.
_{just to save this attracting even more comments on why it was a good/bad choice of default.}

Seems I've never looked for it precisely. It's the first options in the list. thank you. – Reyraa Nov 05 '15 at 07:17

I cannot imagine why anyone would want that to be the default. Thanks for the solution. – Nathan Beach Oct 12 '16 at 12:05
This does not work for me. I have two extra monitors, and about 25% of the time after waking the Mac up from sleep, they flip Spaces. Super annoying. This has been a problem from Mavericks to now (MacOS). – jazzdrive3 May 16 '17 at 19:55

@NathanBeach it helps users that don't understand spaces, so it helps users who *need* it to be the default setting. :) – Florian Wendelborn Jun 25 '17 at 21:00
It does it even if I turn off 'Displays have separate Spaces' – jazzdrive3 Jan 09 '18 at 16:44

This auto-rearranging has been happening for me recently (macOS 10.15), even with this unchecked. Anyone else having this problem and/or know how to fix it? – caleb Jul 08 '20 at 18:08

You can also use the terminal to change the setting.

To disable rearrangement:

defaults write com.apple.dock "mru-spaces" -bool "false" && killall Dock

To enable rearrangement:

defaults write com.apple.dock "mru-spaces" -bool "true" && killall Dock
