Since the introduction of Macs with T2 Chips in late 2017, Apple has released a few different iterations of devices containing the security chip. Currently, Apple has the following Mac types listed for having the T2 Chip:
- iMac Pro
- Mac Pro – starting with the 2019 models
- Mac Mini – starting with the 2018 models
- MacBook Pro – starting with the 2018 models
- MacBook Air – starting with the 2018 models
Not sure if your Mac falls under any of these T2 Chip categories? The easiest way we have found to check is by using the Mac’s 4-digit Electromagnetic Compatibility (EMC) number. An EMC number refers to the devices’ ability to be a good electromagnetic neighbor without causing or falling to electromagnetic interference.
While Mac model numbers can also be used to identify the model type, the same model number tends to be used for a few years over a few iterations of the model and is not quite as unique as a Mac’s EMC number. To narrow down a Mac’s model and release year, we recommend using EMCs. You can find your Mac’s EMC number etched next to its model number on the bottom or back of the machine.
If you match the Mac’s EMC number to one in the list below, it has a T2 Chip:
- EMC – 3144 (Model A1862)
- EMC – 3203 (Model A1991)
- EMC – 3413 (Model A2304 – Rack)
- EMC – 3213 (Model A1993)
- EMC – 3214 (Model A1989 – 2018)
- EMC – 3215 (Model A1990 – 2018)
- EMC – 3358 (Model A1989 – 2019)
- EMC – 3359 (Model A1990 – 2019)
- EMC – 3301 (Model A2159)
- EMC – 3347 (Model A2141)
- EMC – 3184 (Model A1932 – 2018 & 2019)
- EMC – 3302 (Model A2179)
As of April 21, 2020, Apple has not released a standard iMac or MacBook (with single USB-C port) that contains the T2 Chip.
Now that you've determined the Mac has a T2 chip, you can use MacQuisition to create a decrypted physical image. Check out this article for more information.
