I've made a bit of a mess with my Mac whose shell is zsh. The problems started when I used python syntax to run commands, as it's a requirement apart of the project I'm doing to implement CIS benchmarks on my computer. 

* I never had AutomaticCheckEnabled on this Mac, so I was trying to make that change first: 

`command = f"sudo defaults write {self.path} \"^{self.key}\" -int {target}"`.

I think I want instead: `sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate "^AutomaticCheckEnabled" -int 1`.

I think my problem was exactly `"^AutomaticCheckEnabled"`.

I tried to use delete the default, with the command `defaults delete /Library/Preferences/com.apple.SoftwareUpdate "^AutomaticCheckEnabled"`  which errors: `Domain (/Library/Preferences/com.apple.SoftwareUpdate) not found. Defaults have not been changed.` So, I'm trying to figure out the best way to resolve this.

I eventually added the field with the right format, as you can see below here in the output of `defaults read /Library/Preferences/com.apple.SoftwareUpdate`. The old field is at the bottom, needing to be removed.
`{
        AutomaticCheckEnabled = 1;
        LastAttemptBuildVersion = "13.4.1 (22F82)";
        LastAttemptSystemVersion = "13.4.1 (22F82)";
        LastBackgroundSuccessfulDate = "2023-07-24 13:19:33 +0000";
        LastFullSuccessfulDate = "2023-07-24 13:39:11 +0000";
        LastRecommendedMajorOSBundleIdentifier = "";
        LastRecommendedUpdatesAvailable = 1;
        LastResultCode = 2;
        LastSessionSuccessful = 1;
        LastSuccessfulDate = "2023-07-24 13:39:11 +0000";
        LastUpdatesAvailable = 1;
        PrimaryLanguages =     (
            "en-US",
            en
        );
        RecommendedUpdates =     (
                    {
                "Display Name" = "macOS Security Response 13.4.1 (c)";
                "Display Version" = "13.4.1 (c)";
                Identifier = "MSU_UPDATE_22F770820d_patch_13.4.1_rsr";
                MobileSoftwareUpdate = 1;
                "Product Key" = "MSU_UPDATE_22F770820d_patch_13.4.1_rsr";
            }
        );
        SplatProductVersion = "macOS Security Response 13.4.1 (c) 13.4.1";
        TimeOfSemiSplatCompletion = "2023-07-24 13:22:41 +0000";
        "^AutomaticCheckEnabled" = 1;
    }`


I'm looking for guidance on how to fix the  `Domain (/Library/Preferences/com.apple.SoftwareUpdate) not found. Defaults have not been changed.` error from running the command `defaults delete /Library/Preferences/com.apple.SoftwareUpdate "^AutomaticCheckEnabled"`.
