M4 vs M4 Pro: why the storage module is different

Check which Mac mini you have

1. Click the Apple menu in the top left and choose About This Mac.
2. Read the Chip line. It says Apple M4 or Apple M4 Pro.
3. Base M4: our module fits. M4 Pro: wait for the Pro version and do not order the current module.

To confirm the year, hold the Option key, open the Apple menu and choose System Information. Under Hardware, a Mac mini (2024) shows the model identifier Mac16,10 or Mac16,11. Apple lists both under the same model, so the identifier does not separate the M4 from the M4 Pro; the Chip line in About This Mac is the check that counts. The two machines look the same on the outside, so use the software, not the case.

Why one module does not fit both

The M4 Pro logic board is laid out differently from the base M4 board, and the storage module that goes with it is a different part with a different footprint. A base-M4 module does not fit the Pro board, and forcing it risks the connector on the board itself, which costs far more than any SSD.

A Pro module needs its own board layout, its own firmware validation and a full round of testing in real machines. That work is under way. We do not sell a Pro module before it has been through that.

When the Pro version arrives

We do not publish a date until the tests are done. Leave your email on the M4 Pro page and you get one message when it goes on sale, nothing else.

If your Mac says M4 (not M4 Pro), you don't need to wait for that release: check compatibility and see the available base M4 modules. Capacities and pricing for a future Pro version will only be confirmed after testing.
