    19:47 - MacBook Pro thermal throttling, Apple's T2 Security Chip May Cause Issues in iMac Pro, MacBook Pro

    Apple’s T2 chip may be causing issues in iMac Pro and 2018 MacBook Pros

    https://www.digitaltrends.com/computing/apple-t2-chip-may-be-causing-imac-pro-macbook-problems/

    "Many iMac Pro owners have reportedly suffered numerous kernel panics — the MacOS version of the dreaded Blue Screen of Death in Windows — since they hit the market at the end of 2017. You can find a handful of threads on Apple’s community forums, including this one, detailing the trials and tribulations customers are experiencing with their expensive iMac Pros and Apple support. The problems apparently reside in the new MacBook Pro laptops, too.

    Of all the error messages uploaded to these threads, there is one detail they seem to share: Bridge OS. This is an embedded operating system used byApple’s stand-alone T2 security chip, which provides the iMac Pro with a secure boot, encrypted storage, live “Hey Siri” commands, and so on. It’s now included in the new 2018 models of the 13- and 15-inch MacBook Pro with Touch Bar.

    But whether the T2 chip is behind all the kernel panics is up in the air. The symptoms and solutions are varied across complaints, such as iMac Pro owners daisy-chaining storage devices seeing crashes along with those with nothing connected at all. But Apple is aware of the problems and is apparently working on the issue behind the scenes.

    “Looking at the Kernel Panic dumps, looks like someone may have been working on it, as the Kernel Version got bumped from 17.3.0 in January to 17.4.0 yesterday and it feels like I’m seeing fewer panics,” reads one post. “Where it used to panic once or twice a day it now appears to panic once or twice per week.”

    Apple is replacing these machines — in some cases twice — but the problems still occur on the new hardware. One owner said he actually turned off the T2 security chip and never saw a Bridge OS-related problem again. Another user made a Time Machine backup, booted into recovery mode, erased and formatted the system disk, and restored from Time Machine for an error-free iMac Pro.

    Apple suggests that iMac Pro owners wipe and reload MacOS from scratch, disable FileVault, and disable Power Nap, the latter of which worked for some iMac Pro owners.

    According to the threads, the system crashes can be reduced if you don’t daisy-chain devices, don’t use a Thunderbolt 3 to Thunderbolt 2 adapter, turn off Power Nap, turn off Secure Boot, don’t unlock the device with Apple Watch, remove third-party kernel extensions, and turn off every power management option you can find. That’s quite a list.

    Many iMac Pro owners claim the kernel panics actually happen mostly at night when the device is idle, pointing to a possible problem with the storage/hibernation mode and/or the wake-over-Ethernet feature. Several owners report crashing with only an Ethernet cable attached, but that could just be a coincidence.

    Despite the annoying issues stretched across iMac Pro and MacBook Pro, the version numbers displayed in the error logs show that Apple is indeed on the case. An official fix for the hardware kernel panics is supposedly available inMacOS 10.13.6, although the update may not address sleep-related panics"

    According to digitaltrends.com, Apple’s T2 chip may be causing issues in iMac Pro and 2018 MacBook Pros. Many iMac Pro owners have reportedly suffered system issues since they hit the market in December. Many customer support threads on Apple’s community forums detailing the problems and have begun making about the T2 security chip, which provides the iMac Pro with a secure boot, encrypted storage, and “Hey Siri” commands. In response to the reports of computers crashing across iMac Pro and MacBook Pro forums, Apple is working to find a solution. An official fix for the hardware kernel panics will supposedly be available in the next Mac OS update.

    Yeah, he didn't even put a cover over it to bring up the heat. Plus he should have worked at getting an "egg cooking" workload that varied the load to keep the heat up. :cool:

    The thumbnail image teased a much more thought out cooker. ;)

    Hmm true a cover would've helped for sure. I would say just run something like prime 95 or something on loop, but I have no idea if that's on Mac OS or not.

    Eh 90% of all youtube thumbnails are click bait anymore. It's the way to get clicks and any youtuber that doesn't do it suffers from less views. Though I've unsubscribed from 4 youtubers this year alone for click baiting titles way too far.

    Apple runs into another embarrassing issue with the new MacBook Pro
    by BRYAN CLARK
    https://thenextweb.com/apple/2018/0...-embarrassing-issue-with-the-new-macbook-pro/

    "A series of embarrassing gaffes in Cupertino are leading many to question whether Apple has lost its eye for detail.

    Just weeks after Apple acknowledged, then patched, a throttling issue in its updated line of “Pro-level” laptops, users are now reporting another problem that casts Apple‘s quality control in a less-than-favorable light: the speakers. Numerous users have taken to Reddit and YouTube to report or demonstrate the problem.

    It appears that both 13 and 15-inch MacBook Pro‘s have an issue that causes a cracking sound in its speakers, a distortion of sorts that’s present even at a relatively low volume.

    The speakers, it’s worth noting, were advertised as taking “listening to new levels with wide dynamic range and more bass for maximum boom.”

    Apple also noted that these speakers were its best yet, with a direct connection to the power supply that enabled “peak amplification.”"

    New MacBook Pro 2018 Sound Crackling Issue

    My new 15 inch MacBook Pro that I’ve had for just 2 weeks. You can hear the sound issue. I decided to share this video because I think there are many of us out there but few are sharing it. I talked to Apple about this issue and my only course of action is a replacement. But I’m not in a country with an Apple store. So until I’m back in the states; there’s nothing that can be done.


    "It’s unclear at this time what’s causing the issue, although a source familiar with the matter tells TNW the company is aware of the issue, and looking into it. Finding the cause, though, could be troublesome.

    User reports, so far, are all over the map. Some report the issue as one that primarily happens in specific applications, like Apple Music, iTunes, or Garage Band. Others say YouTube videos have the same effect.

    Still others report that they’re also noticing it when using Windows via BootCamp — a problem that may point to a hardware issue, rather than a software “bug.”..."

    Its either the speakers or latency that produce crackling/distorted sounds.

    Report: Intel's 10nm Delay Led to a 2018 MacBook Redesign
    Apple was apparently planning to use Intel's new 10nm processors in the MacBook refresh, but with those chips being delayed until late 2019, Apple was forced to perform a redesign and use 14nm Kaby Lake chips instead.
    By Matthew Humphries, August 17, 2018 11:24AM EST
    https://www.pcmag.com/g00/news/363189/report-intels-10nm-delay-led-to-a-2018-macbook-redesign

    "Next month, it is expected that Apple will launch a new MacBook and with it clear up any confusion for consumers over whether they should buy a MacBook or MacBook Air. But the 2018 MacBook isn't the laptop Apple originally envisioned, and that's Intel's fault.

    According to DigiTimes and VentureBeat, Apple intended to use Intel's new 10nm processors for the MacBook refresh. The move to 10nm would have meant less heat and more performance, meaning Apple could potentially reduce the required cooling, make the laptop even thinner, and potentially increase battery life.

    The problem being, Intel delayed the move to 10nm leaving Apple with a laptop design and no chips.

    In order to still deliver a new MacBook, Apple is thought to have redesigned the laptop so as to accommodate the already available 14nm Intel Kaby Lake processors. They offer more than enough performance for the MacBook, but require tweaks in terms of space and cooling.

    And Apple was 100% sure Intels coming 10nm chips would run a lot colder. I see Apple prefer to continue push out similar overheating throttling junk as Macbook Pro (meaning Apple could potentially reduce the required cooling).

    Soldered CPU. Soldered RAM. Soldered SSD. Same old cooling! Yep. A really "hot" laptop here. Hope you don't mind losing your CPU, good RAM and SSD when a DIMM goes out.

    A little late to the party, but time for TechTips to weigh in on things -
