How bad is the T2 chip crash issue with the new MBP 2019?

Why would you be shocked? The main reason is bc the higher end one has a lower clock speed. I'd rather have the 2.6 Ghz. Now I don't know much about computers, but I just went with the 2.6 6 core
EDIT:
I would've upgrade the CPU if I could get like 2.9 or 3.1. Heck even 2.7 or 2.8 I would've gone with the upgrade.
my last rMBP I upgrade the CPU to 2.6. The regular one came with 2.4
I mainly use my device for safari, notes, weather, Word docs, maps, calculator, mail, YouTube, Live streaming TV on my laptop in the browser, activity monitor, and that's basically it
As far as SSD space, I've never used more than 30-40 GBs

On my iMac Pro the system would just randomly crash with a kernel panic and reboot . Crash report showed a bridgeos error 210.
they replaced it with 2019 2.3 (feel it should have been 2.4)
I have had it less than a week, it has had issues already (keyboard feels okay)
woke up to the error above this morning
Hold the fort....I might have just experienced one on my 15" 2019 MBP.
I unplugged my laptop from power, brought along my time machine backup drive, plugged the drive in and opened up my MBP. My AppleWatch unlocked it and the last open window was my email.
The cursor wouldn't move and I couldn't page through emails. All of a sudden the screen went black and a massive burst of air shot out from the bottom of the laptop fans onto my legs. It then rebooted.
I sent the error report along to Apple as requested.
I attribute this to plugging in the backup drive and then waking the computer with my AppleWatch. Had I waited until it was up and then plugged it in it might have been fine. No idea if this is the T2 crash. Maybe just a random crash - something I never experienced in 4 years on my 12" 2015 MB!

the 8 core lower clock speed is still faster than a higher clock speed like the 2.6. Dont let clock speed make it seem like the 2.6 is faster. What do the 2.6's run at normally under pressure? The reviews of the 8 core show similar clock speed from last years 2018 2.8ghz at around 3ghz.
My 2018 MBP (when I owned one), never experienced it either but others did.
I do think the T2 crashes are getting more and more rare, and the latest patch went a long way. Tbh, if the MBP checks off most of the must haves, then I wouldn't let this issue stop @hajime from buying the MBP.
We've had a 2016, 2017, 2018 and 2019 (various models, 13 and 15, all with touchbars) and never experienced it.
I don't doubt that it happens--I was just lucky. We did get dinged with two keyboard failures on the 2018 model, though.
I personally would be more concerned with the keyboard than the T2 issue. I think it's more widespread.
As soon as you put a name on something, others will attribute similar (or wholly unrelated) incidents to the named cause. Ghosts, UFOs, exotic diseases.... People are comforted by "knowing" the cause of their problem.
Kernel panics and unexplained sleep/wake issues have been around a whole lot longer than the T2. So even while some of those events may truly be due to that particular cause, there are probably plenty of incidents blamed on T2 that aren't actually due to it.
This seems especially true on the web, as "me too" articles/videos on a named phenomenon are more likely to be found in a search. The success of the search doesn't necessarily prove something is a widespread phenomenon, it may only prove the effective use of search engine optimization by the publishers.

Never had a hang on my 2009 Mac Mini, but did go through 2 logic boards, each time it was a complete fail, as in did not power up. The thing always ran hot and I think it just baked the board. It is now back in the original box and is part of old computer wall display.
I just had a Genius Bar appointment with the screenshot error above, plus a few others captured on iPhone video. The Genius Bar staff member just said “I hate the T2 chip”

Reading through the different threads, the T2 crashes happen at random to those that have them.
If it was a specific setup or action that caused them, they would be much easier to troubleshoot
.The T2 crashes seem rare enough now that I would not be too concerned over it.
I will second this — it does seem to be far more rare than it once was from a feedback perspective on this forum. A lot of the noise has died down in recent months.
For those interested, there’s a 100+ page thread on the forum about this on the MBP page...it’s worth reading a few pages deep if you’re considering a 2018/2019 model.
For those that won’t heed that advice, the TLDR version is that the KP crashes seem to be related to certain use cases (i.e. Photobooth oddly enough) and certain machines definitely seem to exhibit the problem more than others. There’s been a ton of users that have received eventual replacements, and the replacement results are all over the map. Some believe it’s a true T2 hardware issue, but I remain skeptical of that since they just announced it alongside the Mac Pro and 2019 MBP.
I personally believe the T2 issue is a combination of a few bad chips out in the wild coupled with complex bugs that take a lot of time to iron out. With the T2 Apple replaced many technologies which were very stable (i.e the entire SMC) and rolled them out all within a single chip. The end result bears several end user security benefits, however the unexpected limitation is that the system tends to KP crash far more often than in comparison to the T1 chip found in 2016/2017 MBPs.
As someone who has had 3-4 actual usage KP crashes that were a result of the T2 chip, I can say I feel that the majority of issues have been ironed at this point in the game. But there are still certain use cases out there that would consistently cause KP crashes. For me, I could consistently reproduce a crash using the Screens VNC application, for example. My advice for people buying a machine would be to load all your software and to use the hell out of the machine in the first 2 weeks of return period to ensure you don’t get a lemon.

On my new MacBook Pro 2019 15" 2.3 / VEGA 20 I had my computer shut down almost every single day.
This morning I finally received a Bridge os error message.
Horrible.. I bought the new one hoping it would resolve the issues from last year, should have known better!

First year can be buggy at times. Best to wait a bit at times I think and not jump into the first run or two of new Electronic products until everyone has complained and reported bug issues.
Since many people in this thread have reported not experiencing issues after a new replacement, is this supposed to be a hardware or purely software failure? I am not sure if we hold the true answer here, but I just wanted to know.
Are there others who experienced this and where it resolved itself a 100%? On my MacBook Pro 15" from 2018 with the 8750H I never had a crash.. So that's why I don't understand what could be the trigger.
My guess would be hardware. I don’t think mine has ever crashed either come to think of it (knock on wood). Mine runs like a Porsche
If they could replace yours you should be good.
NO issues here on my 15" 2018 MBP, purchased in December 2018. I rarely put my laptop to sleep -- generally I shut it down for the night or when I won't be using it for some time -- and I never keep my external drives plugged in all the time. I plug in an external drive when I'm about to use it and when I've completed whatever I was doing with it, I unplug it and put it away. I use spinner HDDs for archival purposes and external SSDs (including TB3) for supplementary files and for current backups.
I try to keep all my stuff on an external drive. I found that this helps keep my MacBook Pro running better. Less on it the less trouble and headaches. The external drive I just plug in also when I need to.
To give you guys an update; computer shut down out of the blue this morning.. when reviewing a T2 related bridge issue had occurred.. there was a Genius Bar spot available so I went to the Apple store today, they said it was definitely not normal behavior, my i9 also ran very hot, you could not even touch the metal area above the touchbar.
At the Apple store they also noticed that the coating from my screen was coming off already (21 days old machine) they said they couldn’t replace it since it was outside of the first two weeks, but they are repairing it. I hope everything will get well!
