Apple’s T2 chip could be behind small number of crashes in iMac Pro, new MacBook Pro

“A number of iMac Pro and MacBook Pro owners have reported issues with macOS enduring kernel panics, with initial investigations into the problems suggesting something connected to Apple’s T2 security chip is to blame — but actual service numbers don’t point to a hardware problem,” Mike Wuerthele and Malcolm Owen report for AppleInsider.

“A common trait found in the error messages is the mention of Bridge OS,” Wuerthele and Owen report. “The Bridge OS is an embedded operating system that is used by the T2 chip, which Apple uses to perform a variety of functions instead of making the processor handle the tasks.”

“While the cause of the kernel panics are unclear, with symptoms and hardware setups varying between users, Apple is seemingly aware of the problem and has been working on it since the start of 2018. One user notes the Kernel Version increase from 17.3.0 to 17.4.0 resulted in fewer panics, reducing the count from a daily occurrence to one that happens once or twice a week,” Wuerthele and Owen report. “In some cases, Apple has reportedly replaced the hardware, but the issue seemingly continued even on the new unit for a few users, suggesting a software conflict of some sort.”

MacDailyNews Take: With the T2 now in the popular MacBook Pros, not just in niche iMac Pro units, hopefully, Apple figures out the issue and fixes it sooner than later.


  1. Uh…sooner would have been BEFORE launching the new Mac.

    Of course, with today’s Pipeline Apple, we have to expect bugs like this to make it out the door.

    Pipeline puts a VERY low emphasis on quality. Both hardware and software have suffered greatly under the “leadership” of Pipeline.

    Pipeline is driving Apple into the ground.

    1. Don’t know what you are talking about. So tired of this whiny “pipeline” verbiage. So sad. Why not just go away if you don’t like Cook’s accomplishments? What have you accomplished? Zero, likely.

      1. Uhhhh, no. We’ve become accustomed to an Apple whose products ‘just work’, not an Apple where every freaking product launch is riddled with problems, bugs, things not working as they should, etc. Since Pipeline Timmy took over that Apple has faded into memory. The products are still better than the alternatives, which is why we still use them, but they’re not the ‘it just works’ products Apple used to tout, and they’re moving farther and farther from that distinction. So no, we WON’T just go away. Perhaps mediocre, which is where Apple is heading, is ok with you but it’s not to us.

        1. If you don’t think Macs suffered from odd bugs and other glitches in the days of Jobs, you have a very selective memory.

          All complex systems have bugs. I’m glad Apple is more proactive to hunting them down as any software vendor. Compare them to, say, Adobe, and you’ll see what I mean.

          1. Of course there’ve were some issued in days past, no one’s disputing that, but if you’re saying things are as they’ve always been then you’ve either been hiding under a rock or are wearing rose colored glasses. ‘It Just Works’ is a phrase that can be applied less and less to Apple products.

          2. I concur with you about Apple’s proactive stance on fixing software problems. And no, of course Macs and other problems weren’t completely perfect under Jobs – but there weren’t problems with the frequency of today’s Apple. There weren’t product lines languishing upwards of 5 years without a significant update.

            I really REALLY hope a lot of this was due to the many distractions that come with such a huge project as bringing Apple Park to fruition and, now that it’s built, they’ll get back on track.

        2. It’s always been this way. You have a selective memory or maybe your too young to know. Computer (and I am counting watches, phones, tablets and desktops as computers) and related software design is a messy business with countless variables and opportunities for error. What you must ask yourself is, “Does the company strive to produce error free releases?” and “When an error is found, how does the company respond?” Of all the computer/software OEM’s on the planet, Apple clearly strives the hardest to produce the best, error free products, and Apple goes the farthest to correct errors they miss. Compare to any other company.

          Throughout all of Apples years the phrase, It Just Works was never 100% true, but it was and still is more true about Apple products than any other company’s products.

          When the first iPhone came out I was astounded as to how well it was manufactured with seemingly no major manufacturing glitches. I mean iPhone 1 just kept on going and going. And this for a first run product unlike anything that had been manufactured on a mass scale before. And who was responsible for that? Tim Cook.

          You complain when Apple creates a product that isn’t perfect even if it is the best in the world, and even though you know Apple will make good on any issues that arise. But at the same time, when Apple works their asses off and takes extended time to make sure it’s right, you same people will be the first to complain that Apple is taking too long to release a product.

          Basically you are just whiners that have no clue as to what it takes to run a company like Apple. With you, Tim Cook is damned if he does and damned if he doesn’t. You give no credit to Cook for sheparding the iPhone to the pinnacle of technology in the world today, or for bringing forth the Apple Watch, AirBuds, Apple Music, ApplePay, HomePod, or for producing the best silicon in the world, or for significantly raising Apple’s position in the enterprise, or for his bold commitment to user privacy and security, etc. Instead you discount his accomplishments with petty complaints about inevitable minor issues that almost always get a quick attention, remedy and apology from Apple.

          You say Apple is heading toward mediocrity. That baffles me. Do you think Apple products are mediocre? To me most of Apple’s current pipeline products are by far best in class. Tim’s pipeline produces the best products in the world and Apple’s enviable position in the world has never been stronger.

          If you think Cook is so bad, name an able replacement. You can’t. Steve Jobs knew what he was doing when he put Cook in his place and if Steve could see where Cook had lead Apple up to this point, he would more than dazzled by Tim’s success. When you belittle Cook’s leadership, you are really belittling Steve’s wisdom and another one of Steve visionary decisions. That’s right, I said it, putting Tim Cook in charge of Apple was one of Steves Jobs’s greatest calls.

          The problem is, you Cook haters don’t think for yourself, you just repeat the same nonsense you hear from other Cook hating stooges. You’re just like the Android fan that always rationalizes some bullshit criticism of Apple. You can never objectively evaluate for yourselves, you just echo what hear from your closed network of idiots.

          Your complaints are petty and narrow minded. You see some selected small things but you can’t seem to see the big picture. Yes there are problems that will be corrected, but removing Tim Cook from Apple would be a disaster in comparison.

          So yeah, we don’t need to hear the word “pipeline” as some sort of sophomoric adjective of derision for Tim Cook anymore. You have worn it out, and it makes you sound like an under achieving thirty year old living in your parent’s basement.

          1. And might I add that Cook accomplished all these thing against the headwinds of several mind-boggling distractions that Steve left for him: Going “thermonuclear” on Samsung in court, overseeing the building of Steve’s radically designed Apple Park, and then moving the heart of Apple business into the new headquarters. All of this while continuing to grow Apples core business. It is plain to see that Tim Cook has done a truly outstanding job.

  2. I had this issue on my iMac Pro consistently but only when a third party app was installed which seemed to be causing the problem. It was “Cinch” which brings Windows 7-esque aero window snapping to the Mac. After I figured that out and uninstalled it, I’ve had zero issues for months now.
