[PowerShell] macOS 15 Sequoia compatibility script to check your fleet with optional System Group creation

[JuergenKlaassen]

Hi Folks

Excited about the upcoming macOS 15 Sequoia? 
You might want to do a sanity check on your fleet of macOS devices ahead of it to plan the update and deployment process. Pretty sure you will get requests from users and some might be unlucky if they're running incompatible systems. 
I have a script for you to determine the status for each system and optionally create a System Group on JumpCloud with compatible devices. 

# List of compatible Mac models for macOS Sequoia
$compatibleModels = @(
    "Mac13,1", "Mac13,2", "Mac14,10", "Mac14,12", "Mac14,13", "Mac14,14", "Mac14,15",
    "Mac14,2", "Mac14,3", "Mac14,5", "Mac14,6", "Mac14,7", "Mac14,8", "Mac14,9",

    } else {
        Write-Host "Failed to create the new group: $groupName" -ForegroundColor Red

P.S.: If you need a Dynamic Group with devices running on Sequoia (i.e. for evaluation purposes), here you go:

Instead of this:

# List of compatible Mac models for macOS Sequoia
$compatibleModels = @(
    "Mac13,1", "Mac13,2", "Mac14,10", "Mac14,12", "Mac14,13", "Mac14,14", "Mac14,15",

    "Mac15,10", "Mac15,11", "Mac15,12", "Mac15,13", "Mac15,3", "Mac15,4", "Mac15,5",
    "Mac15,6", "Mac15,7", "Mac15,8", "Mac15,9", "MacBookAir10,1", "MacBookAir9,1",

    "iMac19,1", "iMac19,2", "iMac20,1", "iMac20,2", "iMac21,1", "iMac21,2", "iMacPro1,1"

which is cumbersome, wouldn't a regex be more efficient? Less text and less space for error when copying and pasting.
