# Package Requirements

What a macOS package has to carry before Easy2Patch will send it to Intune, and the limits Intune itself imposes.

### Required fields

| Field                                  | Rule                                                                                                |
| -------------------------------------- | --------------------------------------------------------------------------------------------------- |
| **Package**                            | A `.dmg` or `.pkg` file. The type is read from the package; it is not chosen on screen.             |
| **Primary bundle ID**                  | Required. The main application bundle Intune looks for on the device.                               |
| **Primary bundle version**             | Required. The version Intune compares against when version detection is in use.                     |
| **Included apps**                      | At least one entry, each with a bundle ID. This list is the detection rule — see Deployment Models. |
| **Minimum supported operating system** | Required. Devices below this macOS version are not applicable.                                      |

{% hint style="info" %}
Where the package allows it, these values are read out of the package itself. Where a package cannot be read, the fields are **left empty and the reason is shown** — they are never filled in with a guess. An operator completes them by hand.
{% endhint %}

### Limits

| Limit                                    | Value                  | Applies to  |
| ---------------------------------------- | ---------------------- | ----------- |
| Package size                             | 8 GB                   | DMG and PKG |
| Included apps                            | 500 entries            | DMG and PKG |
| Pre-install / post-install script length | 15,360 characters each | PKG only    |

### Minimum supported operating system

The value is stored as the Graph key Intune uses, and offered on screen from newest downwards:

macOS Tahoe 26.0 · macOS Sequoia 15.0 · macOS Sonoma 14.0 · macOS Ventura 13.0 · macOS Monterey 12.0 · macOS Big Sur 11.0 · macOS Catalina 10.15 · macOS Mojave 10.14 · macOS High Sierra 10.13 · macOS Sierra 10.12 · OS X El Capitan 10.11 · OS X Yosemite 10.10 · OS X Mavericks 10.9 · OS X Mountain Lion 10.8 · Mac OS X Lion 10.7

An application created earlier may legitimately carry a value from further back than the picker offers. Existing values are never rewritten to fit the list.

{% hint style="warning" %}
Microsoft's published list and what a live tenant offers do not always agree — the documentation sample lags behind the portal. Compare this list against your own tenant's Requirements screen during rollout and use what the tenant shows.
{% endhint %}

### Intune management agent versions

These are properties of your fleet, not of Easy2Patch. Easy2Patch cannot see the devices and therefore does not enforce them; they are listed so that a failure on an older Mac is recognisable.

| Feature                              | Minimum Intune management agent |
| ------------------------------------ | ------------------------------- |
| Unmanaged PKG applications           | 2308.006                        |
| Pre-install and post-install scripts | 2309.007                        |

### Architecture

The inspector reports one of **Universal**, **x86\_64** or **arm64**. Anything else is stored as unknown rather than forced into one of the three.

Architecture is informational on macOS. It does not become a requirement rule — macOS applicability is expressed by the minimum supported operating system and nothing else.
