This script was designed to be used as an Extension Attribute on Jamf Pro server to ensure specific requirements have been met to deploy macOS Ventura. With little modification it can probably be used on other systems (Jamf Pro server requires the output of an Extension Attribute to be echo "<result>$FOO</result>).
- OS X 10.9.0 or later (It seems, as of the day I write this Apple has not yet made recommendations, this page and the script will be adapted if necessary when the information will become public)
- 4GB of memory (It seems, as of the day I write this Apple has not yet made recommendations, this page and the script will be adapted if necessary when the information will become public)
- 60GB of available storage, the required storage is different when upgrading from Catalina (33,5GB) or from older versions (44,5GB) and accounts for the size of the installer (almost 13GB)
These last 2 requirements can be modified in the first 2 variables (MINIMUMRAM and MINIMUMSPACE).
- REQUIREDMINIMUMRAM: minimum RAM required, in GB
- REQUIREDMINIMUMSPACE: minimum disk space available, in GB
- MacBook (2017 or newer), ie MacBook10,1
- MacBook Pro (2017 or newer), ie MacBookPro14,1
- MacBook Air (2018 or newer), ie MacBookAir8,1
- Mac mini (2018 or newer), ie Macmini8,1
- iMac (2017 or newer), ie iMac18,1
- iMac Pro, ie iMacPro1,1
- Mac Pro (2019 or newer), ie MacPro7,1
- Mac Studio (2022 or newer), ie Mac13,1
- MacBook Air M2 (2022 or newer), ie Mac14,1
Default compatibility is set to False if no test pass (variable COMPATIBILITY)
The extension attribute will also display false for a computer that is compatible but already running Ventura.
Copy the content of the script (.sh file) to a new Computer Extension Attribute or just download the existing Extension Attribute (.xml) file and upload it to the Computer Extension Attributes of your Jamf Pro server.
