Apple has confirmed that the third-generation keyboard on 2018 MacBook Pro models

is equipped with a "membrane" to "prevent debris from entering the butterfly mechanism.

  1. 1The new 15-inch MacBook Pro with Touch Bar models support DisplayPort at High-Bit Rate 3 (HBR3),

  2. 2a signal standard of both DisplayPort 1.3 and DisplayPort 1.4. Apple says the dedicated Radeon Pro graphics can drive up to two 5K displays at 60Hz, each over a single stream.

  3. 3The new 13-inch MacBook Pro with Touch Bar models support DisplayPort at High-Bit Rate 2 (HBR2),

  4. 4a signal standard of DisplayPort 1.2. This is a limitation of the Iris Plus Graphics 655 in these models, as Intel's integrated GPUs do not support DisplayPort 1.4.

What that means:

  1. 5The new 15-inch MacBook Pro theoretically supports DisplayPort 1.4, which Apple confirmed, but at least for now, it still can't drive an 8K display. It could be possible with VESA's lossless Display Stream Compression standard, perhaps, but it's unclear if this can be enabled down the road.

  2. 6For now, then, the new 13-inch and 15-inch models have the same compatibility with external displays as the previous-generation MacBook Pro: up to two 5K displays or up to four 4K displays on the 15-inch model, and up to one 5K display or up to two 4K displays on the 13-inch model.

For comparison, 2016 and 2017 MacBook Pro models are equipped with Intel's JHL6540 Thunderbolt 3 controller, which supports DisplayPort 1.2.

In related news, Apple has also confirmed that all four Thunderbolt 3 ports on the new 13-inch MacBook Pro with Touch Bar are now full speed, compared to only the two left-facing ports on the equivalent 2016 and 2017 models.

T2 Chip, Benefits

The current benefits specific to the T2 chip are in improved security, the potential for better internal SSD performance, enhanced tone mapping in the FaceTime HD camera, and in the case of MacBook Pros, the Touch Bar.

The T2 chip integrates the System Management Controller (SMC), an image signal processor, an audio controller, an SSD controller, and a secure enclave processor. Although future versions of macOS will undoubtedly enable more features of the T2, perhaps including facial recognition, those currently available fall into three groups: security, storage, and image.

Security features include:

  1. Encrypted storage. All internal SSD storage in Macs with T2 chips is encrypted, either using keys based on the T2 chip alone, or in conjunction with a key supplied as part of FileVault. As the latter appears to come at no performance cost, everyone using a Mac with a T2 chip should enable FileVault. There doesn’t appear to be an option to disable the default encryption performed by the T2.

  1. Secure Boot. There are three levels provided, ranging from Full to None, and you can additionally disallow booting from external storage. These are configured in the Startup Security Utility, which is accessed from Recovery mode.


At present, the most serious issue with T2-equipped Macs is that they cannot boot from network volumes. If your Macs need to support network booting (NetBoot, NetInstall, or NetRestore), then they must not have T2 processors. Apple hasn’t, as yet, provided any workaround for this.

Any damage to the T2 chip could result in it being unable to decrypt the contents of internal SSDs. As a result, Apple stresses the importance of maintaining good external backups. You can’t, for example, simply pop the SSD out and access it from a drive enclosure using another computer (in any case, most of these SSDs are now soldered in too!). Because keys from the T2 chip are used in the encryption process, decryption can only occur when that exact same chip is able to perform the decryption (although some forensic tools may now be able to work around such encryption).

The combination of T2, FileVault, APFS, and soldering-in of SSDs is probably going to make recovery of data from an internal SSD practically impossible, for the foreseeable future.

2018 MacBook Pro T2 Chip can erratically kernel panic the system.

The new MacBook Pros with T2 chips do indeed kernel panic randomly,

Why does it seem like Apple rushed a beta-quality product out the door?

Because that’s what Apple did!

Shortly after release the firmware had to be updated to deal with a performance-throttling bug.

The kernel panics are another issue.

Is the 2018 MacBook Pro ready for prime time for a pro user depending on it to not go haywire?
