⌘⇧S (Command + Shift + S)- not working

What it sounds like is you want the OS to behave as it did for decades before Apple moved the keyboard shortcuts around starting in Lion.

a) Open the System Preferences. Click on Keyboard, then the Shortcuts tab.

b) Click on App Shortcuts in the left column, then click the + button below that.

c) This box will appear.

d) In Menu Title:, type Save As and then press Option+; to get a true ellipses. Do not type three periods.

e) Highlight the Keyboard Shortcut: field and press Command+Shift+S .

f: Click the Add button.

Close the System Preferences. Save As will now be Command+Shift+S in all apps.

Have you ever created an ⇧⌘S keyboard shortcut for any Automator application or Quick Action, or in any other application in System Preferences > Keyboard > Shortcuts > App Shortcuts? Are you using Karabiner to remap keyboard keymaps or any other application that intercepts that keyboard shortcut? Is the current input source set to U.S. or is it on some other language such as ABC- Extended?

I created a new user, and ⇧⌘S key combination does work there. Does that help you in anyway? Clearly this is something to do with my actual user.

Yes, quite a bit, actually. It tells us the problem is specific to something in your main user account, and not the OS.

Restart to your normal account while holding down the Shift key so you startup in Safe Mode. Everything should work normally since only certain items are allowed to load. Assuming this works as expected, you need to find out what's loading in a normal startup that's interfering with the menu options.

You can start with EtreCheck. It's free to use. Run the app, then copy/paste the results back here. All personal info is automatically redacted from the report. We'll be able to see what processes are running and what may be lurking in the Daemon folders. Make sure to post the results into the extra info field as they're too long to post in the main editing window. Third icon from the bottom right of this editing panel.

I don't have Office so I can't help there. However, in Pages, Pixelmator Pro, Preview and I imagine a host of others "Save As…" is the same, command option shift S.

If neither of those help, try…

Pages 11.2 uses command option shift s.

You can try a couple things…

First, make sure "Enable Full Keyboard Access" is disabled in System Preferences > Accessibility > Keyboard.

Try booting into Safe Mode then restart normally.

The correct Save As… keyboard shortcut for Pages has been discussed. However, if you are menu-driven, just the option key will transform the duplicate menu item to Save As…

Keyboard Shortcuts for Pages

As far as Pages v11.2 on macOS 12.0.1 is concerned, the Duplicate command ⌘⇧S works correctly producing a duplicate of the currently open document with the word "copy" added to the name. LibreOffice Writer v7.2.3, in keeping with its Word clone nature, does not offer a duplicate menu item, and uses ⇧⌘S for Save As… For multi-platform distribution, it probably uses Qt, instead of Apple's Cocoa. The Qt library on the Mac attempts to map as much as possible to the Cocoa appearance.

Preview, with an open PDF document, will open a new window with the name "copy" appended to the filename when one uses the ⇧⌘S keyboard shortcut.

I am testing these on a 16-inch MacBook Pro M1 Pro running macOS 12.0.1.

FWIW, in Preview and Pages command shift S creates a duplicate in a new tab, same window.

'Duplicate' in Pages, Preview and Pixelmator Pro is not working. ⌘⇧S is a standard keyboard for all of these. I am not attempting to change anything.

Yes, that's different than what I thought you were saying.

In Pixelmator Pro, "Duplicate" is command shift S. In Preview and Pages "command shift S" does create a duplicate for me.

There's quite a bit of unnecessary software going on here. These are from the list of stuff installed in the last 60 days. You may have already deleted some of them.

Displaperture - Eye candy that does nothing but add overhead to the system. I'd remove it.

CopyClip - Up to you. Lots of people like being able to get back to various clipboard grabs. But each one does take up more RAM as you go.

GetRate - Another app unnecessarily taking up system resources. You can get that information without an app here. Rates are updated every week.

Simple Antnotes - More unneeded software. Stickies is included with the OS and already does this.

Adblock Plus - I've tried this and found it both invasive and doesn't work all that well. K-Block! is a much better ad blocker. Not only that, you have both Adblock and Adblock Plus on your Mac. More than one of any ad blocker is trouble. Adblock Plus also caused at least one crash of Safari, as noted in the report.

ExpressVPN - Delete. Seriously. Unless you use a VPN for its actual purpose of communicating with an office server, it's useless. Public VPNs are anything but private.

Back to the top of the report to look at running processes.

There are just so many third party apps going. Any of them could be the problem. Slack, MagnetLauncher, HourLoginHelper, who knows. Start removing them a couple at a time and test to see if the menus go back to normal.

Delete Chrome. It's a known, massive resource hog. On top of that, from the moment you turn your Mac on to the time you turn it off, it is constantly sending anonymized data of your computer and web usage to Google's servers. Chrome doesn't even have to be running. The keystone agents

/Library/LaunchDaemons/google.keystone.agent.plist

/Library/LaunchDaemons/google.keystone.xpcservice.plist

do that by launching apps buried within the Chrome app, which load at startup. And then there's this.

We don't allow any software written by Google on our Macs. Not Chrome, Google Earth, or anything else. Google's real business is collecting marketing data. You are their unwilling and unpaid source for it when you use any of their junk. If Safari isn't a browser you care much for, try Firefox. If you have one, you do not need Chrome to access your Google account. You can do that from any browser.

Remove Chrome and its daemons. Never install it again.

In normal mode. Otherwise, the processes we would want to see that are interfering won't be loaded.
