Some 2018 MacBook Pro and iMac Pro users reporting crashes, possibly due to Apple's T2 processor and Bridge OS; some fixes in macOS 10.13.6, no complete fix yet

Context & Ripple Effects
This lands one day after Apple shipped a supplemental update for 2018 MacBook Pro CPU throttling, making it the second stability complaint about the same launch-cycle hardware in as many days — this time crashes on the 2018 MacBook Pro and iMac Pro, tentatively tied to the T2 processor and Bridge OS.
The T2 thread runs long in this coverage: four years later the same chip would brick Macs during the Monterey upgrade until Apple issued a dedicated firmware fix, which makes today's unconfirmed T2 link less a one-off bug than an early data point on a chip that concentrates boot, security, and SSD control in Apple's own silicon.
First-order effects
- Owners of brand-new 2018 MacBook Pro and iMac Pro machines are running flagships that crash without a complete fix, with only partial relief arriving inside macOS 10.13.6.
- Apple is absorbing the cost through incremental OS updates rather than hardware action, stacking this crash patch on top of the just-released throttling update for the same product generation.
Second-order effects
- Each patch cycle pushes more of the diagnosis burden onto users and support channels while the root cause sits in firmware Apple has not fully addressed, pressuring the company to treat Bridge OS updates as a first-class release track.
- Buyers weighing the new models against prior-generation Macs get a fresh reason to wait for a proven-stable revision, softening early demand at exactly the moment Apple is defending the redesign.
Third-order effects
- If the T2 keeps surfacing as the common denominator — from these crashes to the later Monterey bricking episode — Apple's consolidation of security and storage control into its own silicon turns every firmware defect into a full-system failure only Apple can repair, raising the stakes of each OS release.
- The pattern reinforces a structural dependence on Apple's update pipeline as the sole remediation path for hardware-level faults, echoing earlier episodes like the macOS 10.13.2 mitigation for Intel's memory access flaw.
The trend: As Apple folds boot, security, and storage into its own T-series silicon, firmware bugs become machine-wide failures whose only fix ships through macOS updates — making each OS release a de facto hardware recall mechanism.
