T2 Security Chip Possibly Causing System Crash On 2018 MacBook Pro


iMAc-Pro-motherboard-Apple-T2-chip-iFixit-001Some MacBook Pro 2018 and the iMac Pro user are complaining about system crashes. This kernel panic may be caused by the T2 chip, which should provide extra security.

Apple was quick to solve the heat problems in the MacBook Pro with a software update, but they can immediately continue with the following user complaints. Some owners of the new MacBook Pro 2018 experience system crashes, sometimes several times a day. This problem seems to be connected to the T2 chip, as the iMac Pro is already bothered by this.


The iMac Pro appeared late last year and was the first Mac with a safe and special T2 chip. This chip takes on all kinds of tasks from other chips from the previous models and regulates, for example, the encryption of the storage and ensures safe booting, in addition to functions for the FaceTime camera and microphone. Ever since the introduction of the iMac Pro, some users have complained about system crashes, a so-called kernel panic. The system logs show that this is caused by Bridge OS, a separate operating system that controls the T2 security chip.


T2 chip system crash on 2018 Macbook pro happens especially when it is put into sleep mode, because after the startup the message appears that the Apple MacBook pro had to be restarted due to a problem. It is still unclear at the moment when this problem occurs exactly. Some users say that it plays when connecting external storage, but there are also cases where this is not necessary. Apple has replaced the Macs with a number of users, but without result. So it seems to be a software error.

Apple has in the meantime made some adjustments that reduces the number of system crashes. But a definitive solution is not yet available. Apple has given suggestions to reduce the problems, but they are not very efficient.

According to Apple, it will help to completely reinstall macOS and disable FileVault and Power Nap. Disabling Power Nap has some effect on some users, while others say the number of crashes is also reduced by not using a Thunderbolt 3-to-Thunderbolt 2 adapter, disabling Secure Boot, unlocking your Mac with remove the Apple Watch, third-party kernel extensions, and disable power management options.

This temporary solution will only be a good thing for a few Mac users, so it is hoped that Apple will soon come up with a definitive solution.
