Stockholm Syndrome.

Just as likely you’re living in the past.

How is it possible that my older MBP on Mavericks manages to run it fine and smooth while their supposed latest and greatest which costs 1k more with 5+ more years of hardware improvements struggles to? It’s straight up embarrassing. They really need to fire their software engineers and have another major shake up or something. Don’t care about the hardware when their software, the heart and soul, is no longer roaring like it used to.

Consider that most everyone else’s 2018 MBP works just fine and your MBP is having problems so you need to have Apple service address this and not complain to these forums like you’re helpless.

SMH. Boggles the mind with all that cash pouring in and this is the user experience for Mac users.

This is not the user experience for MBap users.

Dude lol.. not to burst your bubble, but look around you.. it's Apple, they've bloating OSes forcing people to upgrade since like forever, not only them by the way, almost the entire tech industry sadly. Get a, say, Iphone 6 or 5s on iOS11 and run it side by side with a, say, Galaxy S4, or Nexus 5 or whatever older Android device, observe app loading times, animations lag, letters stuttering on simple messages typing, etc.

The difference in performance is abysmal. Older iphones on iOS 10 outperform iOS 11 ("supported" according apple). The apple consumer will call this "support". Don't get me wrong, Android is far from perfect with it's "support (older device not so much)", but bloating the OS as to make it unusable is not one of them. Some old Android devices will even outperform Apple's still selling line (6, 6s, 7) and then you have the people posting iphone X benchmarks here as if in a couple of upgrades they ain't gonna be bloated as well.

They do it with their star product, imagine the Mac line, these latest ones scream cash grab all over.

What are you smoking?

These KPs happen on the 2017 iMac Pro as well. The sad thing is that they have been happening since 2017...

Not on mine.

I love your wet salmon reference, very funny. Personally, there's a positive: I find the keyboard faster to use, looks nicer, however: I have less confidence my fingers are on the keys properly (gap between the keys, full left and right cursor keys instead of half keys), prefer not to make so much noise typing.

ps -- sorry to be off topic. I'm tempted on the 2018 MBP, but once these problems are ironed out.

There are plenty working great, FYI, I own two of them.

 

[tehStickMan]

This update fixed zero of the audio issues I had, and I had all of them I believe.

Nice to hear it. It's hard to get a sense of % of MBPs with issues.

 

[tehStickMan]

Nice to hear it. It's hard to get a sense of % of MBPs with issues.

And you will never get a realistic number. The throttling and audio issues are only apparent if you REALLY pay attention, and check everything with a fine tooth comb.

How’s about updating your software so it doesn’t pi$$ing stutter? I recently copped one of these and even Safari stutters when scrolling simple sites, I was shocked given the hardware and high price. Straight up embarrassing from Apple and goes to show it’s the software that really matters. Don’t care about pointless benchmarks. Will be returning mine as it doesn’t feel it’s worth £2,699 at all.

Edit: Running the latest Mojave beta which is supposed to be smoother but it isn’t? I guess you people had a different definition of ‘smooth’ to me. I can’t straight from a late 2013 MacBook Pro running Mavericks and it’s shocking the difference in smoothness (and design too which is hideous looking in comparison to Mavericks in my opinion).

God knows how Apple would manage developing an OS like Windows for BILLIONS of hardware combinations.

Apple can't even develop a stable OS for the 10 or so hardware configurations they haven't forced obsolescence on....

Ouch. That’s a powerful statement with a bit of a valid point. However I still find macOS to be far superior of an OS.

 

[Burger Thing]

Well done Apple.
Now release a firmware update so the keyboard doesn’t feel like you’re typing on a salmon.

Ha Ha, this has to be the funniest comment I have read for a while.

And as an owner of a new MBP i9, I have to agree wholeheartedly.

 

[Pangalactic]

Ouch. That’s a powerful statement with a bit of a valid point. However I still find macOS to be far superior of an OS. That said, Apple needs to get these kinks worked out immediately. They should be embarrassed right now.

The issue is that Windows has to keep A LOT of backward compatibilities since a lot of businesses rely on it. For example, I went a couple of days ago to Chase bank to open a business account. Guess which browser they used? Internet Explorer! Same applies to a lot of applications that have been designed with IE usage in the background. And Windows has to keep all of this functional and it takes them a really long time to move ahead because of this.

Meanwhile, Apple moving ahead at the speed of light can't even design a non-crashing MBP when there are just TWO MODELS two support it! Wonderful. And keep in mind that while Windows is making a lot of progress with Windows 10, MacOS has been more or less stagnating for the last 5 years or so.

Speculation.

Even if that was remotely possible it only takes a few megahertz to manage sound output, as anyone over 40 knows.

I have a 2018 MBP 15 with T2 BridgeOS panic and Apple replaced it for free after all the software fixes. The new one has absolutely no issue with T2. So hardware not software issue.

"only takes a few megahertz to manage sound output"

T2 handles SSD on-the-fly encryption and serves as SSD controller, and it also controls the camera, light sensors, spectrum sensors and display temperature on 2018 MBPs, that's a massive overhead if they need to rely more on Intel CPU to handle those tasks, even if that's just crosschecking to increasing redundancy.

T2 also handles all the 4-way beam forming, noise-reducing microphones in addition to the quad-channel HiFi speakers.

T2 also handles the Touch Bar, BridgeOS, ApplePay and the second generation TouchID.

T2 also handles always-on "Hay Siri", live speech recognition and dictation.

T2 also handles various system management controllers, or SMCs, serving as the root trusted chip for the 2018 MacBook motherboard, directly offering firmware-level authentication service.

T2 also handles power management, over 20 temperature sensors and PID differential motor control for both fans.

Can you go to itunes radio and while listening mute and unmute several times, and let us know if you hear i high pitch sound ?

 

[Peperino]

The 2108 Throttlebook Pro has gotten off to a terrible start. Worse when you consider it builds upon the controversial 2016/17 Mabook Pro to begin with.

Apple just needs to end the Mac because they seriously do not care about it.

AKA soldered donglebook Pro. The Pro is for how many dongles you actually need in order to use it.

Furthermore they made it worse since now RAM and HD are now soldered, still no mag safe and still cannot connect your own iphone ipad.

I was waiting on 2016 Macbook Pro to came out to buy 2 new Macbook for my kids. They were so bad I ended up buying the 2015. Now is even worse since they are more expensive and there is no option without a touchbar.

 

[sjinsjca]

Agreed... my 2018 15" MBP is flawless so far. No kernel panics, no crashes, no crackling. Could these issues be, at their root, some sort of software-stack issue? I'm having trouble imagining how it could be hardware or OS if it is not more widespread.

Empty all your cache folders.

I've emptied everything that I can find with Onyx - tmutil trimmed local backups (TM is turned off) etc - can't think of anything else to do.

Apple phone support was useless (I asked for a terminal command and they told me: "ok, first open a terminal, then type "$" dollar sign, space"
Me: "erm, the dollar-space is not part of the command - that's the command prompt"
Apple Support: "no, it says here to type dollar-space"
Me: "sure, ok")

Calc all sizes shows that my system should only be using about 30GB, rather than 85GB...
Anyone know

What a nonsense.
So because you don't have a problem on a new machine, it's definitely hardware issues. Right. My machine didn't have any problem for a week. So what happened with the SoC? It "just broke"?

I'm observing the thread on forum and from all posts you can conclude one thing: nobody knows **** they talk about.
Clearly the issue isn't as widespread as some suggests. Yes, there are 90 pages of the topic, but some folks, like @StudioSanctum have a lot of posts there – I mean this guy is on almost every ****ing page. Sure there are many visits, but I made there at least 100 visits alone. @StudioSanctum probably doesn't work and stays on this forum whole day and refreshes the website every minute or so.
For example: I had 2 crashes after installing Mojave and downgrading to High Sierra on August, 24th.
I've googled panic string:
"macOSPanicString" : "BAD MAGIC! (flag set in iBoot panic header), no macOS panic log available”
Guess what? There are only 4 search results...

Clearly there are different issues, some have macOS panics, some have bridgeOS panic, in some cases it's related to some extra kexts installed on the OS, in some cases probably it's really hardware issues, maybe bridgeOS 3 isn't fully compatible with High Sierra (because downgrade isn't supported), etc.
Don't get me wrong, I can't work on this **** too. The crash on a new machine is so distracting and pissing off that it's hard to imagine.

Are the 2018 Macbooks Pro ****ed up? YES.
(beside the issues it's really nice machine imo)
Someone responsible for this hardware (or hardware/software integration) should be fired.

But guys, chillout. Instead of wasting time here by finding magical cure for different issues, go on f***ing https://www.apple.com/feedback/macbookpro.html or https://bugreport.apple.com/web/ and spam them after each crash you have.

Wait to late September at least if you wan to buy it.
Thanks

Young man, please don’t post irrational speculative stuff to people three times your age who have been using Macs since the 80s. Your new machine came from the same production run with the same fabrication process as the one you had last week. Nothing changed hardware-wise. You experienced some bugs before and are not now. Good luck.

 

[Nozuka]

I have not experienced any of these problems yet and i got the MBP since july.

People with the problem should just go and exchange the machine.

Just to play devil's advocate, drivers in Windows are mostly the responsibility of third-party manufacturers, so Microsoft don't have to do too much except provide and manage the SDK. Still, it works surprisingly well for such a diverse platform.

 

[Delgibbons]

My 2018 MBP encountered a "bridge OS" kernel panic this morning. So then I installed the update. Not even an hour later it happened again. I've had 8 of these happen since owning the product. So disappointing.

Time for an apple Kernel Panic BSOD meme.....

Ouch. That’s a powerful statement with a bit of a valid point. However I still find macOS to be far superior of an OS. That said, Apple needs to get these kinks worked out immediately. They should be embarrassed right now.

I love the look of OS X: no denying that it looks sexy. I just find windows (even 10 which has had its own cluster**** moments mainly involving forced updates - wonder where Microsoft got that idea from) to fit my work better and has been incredibly stable. Haven't had a blue screen on my desktop computer for years. Each to their own though

The latest build Windows 10 is finally moving on from some of those legacy areas in terms of the style of certain elements jarring with the new style they have.

Then again maybe phasing things in gradually is the best way to do it..

I quite like the 'clackity clack' it reminds me of the old IBM ps2 type keyboards back in the day.

For what it's worth. I havent had any issues with my 2018 13" MacBook Pro at all. No kernal panics or crackling or anything. I'd say it's the best laptop I've ever had, and runs like a dream.

I'm not saying that these issues don't exist and that they shouldnt be fixed. But I think there is a tendancy, particulary on forums like this, for issues to apear to be more widespread than they actually are. For the people that are affected, I competey understand their frustration.

Apple on Tuesday released macOS High Sierra 10.13.6 Supplemental Update 2, exclusively for 2018 MacBook Pro with Touch Bar models, but the release notes only mention improved stability and reliability.

When contacted by MacRumors for clarification, Apple said the Supplemental Update improves system stability and reliability across a number of areas, and addresses several issues, including crackling audio and kernel panics. Apple said it recommends all users install the update on their MacBook Pros.

The 1.3GB update hasn't been available long enough yet for any conclusive evidence from affected users, with mixed reports across the Apple Support Communities, Reddit, and our own MacRumors discussion forums.

Apple Support Communities user takashiyoshida, for example, claimed his MacBook Pro "no longer outputs the crackling noise" after updating.

"This evening, I set the microphone and speaker's sampling format to 44100 Hz and began playing back music on iTunes," he explained. "Before the update, I would normally hear the noise in about an hour. I left my MacBook Pro to play music for about three hours and so far I am not hearing any noises."

Reddit user onceARMY, however, commented that he was "still getting audio crackling noise while playing YouTube content on Safari." He did note that there were "no issues with the Spotify app" after installing the update.

As far as kernel panics are concerned, a handful of users have reported experiencing at least one since installing the Supplemental Update.

"Installed today's update... and then it happened," wrote MacRumors forum member King724, referring to a kernel panic. He shared a log indicating a system crash related to bridgeOS, the device firmware on the logic board that controls many functions on the 2018 MacBook Pro, including the Apple T2 chip.

Last month, Apple said it was looking into a small number of indirect reports about the kernel panics, but wouldn't say if the T2 chip was to blame.

Similar reports of kernel panicking began last year with the iMac Pro, which is also equipped with the T2, so it did--or perhaps still does--seem to be a potential issue with the chip, or the bridgeOS firmware that manages it. There was some speculation that the T2 chip was also to blame for the crackling.

For context, the T2 chip integrates several previously separate components, including the system management controller, image signal processor, audio controller, and SSD controller. It also features a Secure Enclave coprocessor for secure boot, encrypted storage, and authenticating Touch ID.

Prior to yesterday's Supplemental Update, Apple support representatives provided customers with a wide variety of potential solutions to mitigate these issues, ranging from disabling FileVault to turning off Power Nap, but none of the workarounds appeared to permanently fix the problems.

Apple also asked some customers if they would be willing to send in their MacBook Pros so that its engineers can look into the issues. Some customers were apparently told that fixes were in the works, and at least based on what Apple told us, they are included in the Supplemental Update.

This is the second macOS High Sierra Supplemental Update for the 2018 MacBook Pro in as many months, with the first addressing a bug that contributed to excessive throttling of clock speeds under heavy thermal loads.

The Supplemental Update is not available to macOS Mojave users, but the issues could be resolved in future beta versions.

My 2018 MBP encountered a "bridge OS" kernel panic this morning. So then I installed the update. Not even an hour later it happened again. I've had 8 of these happen since owning the product. So disappointing.

I never had any problems with my macbook Pro 2018 but yesterday I installed this new update and today I got this Bridge OS problem for the first time, also after booting up my computer again I heard strange voices from the speakers. So I think this update brings me those problems and not fixed it.

Ever since Apple redesigned and updated the MacBook Pro in 2016, there's been nothing but bad news and problems with them. Even more infuriating is how expensive these laptops are. At this point, the redesigned MacBook Pros have a tainted image that I certainly don't want to be a part of.

Get your **** together Apple, making great laptops should be child's play for you. Lay off the iPhone green for a while and sober up.

And yet i've owned the 2016, 2017 and now 2018 versions and I can honestly say they've been the most enjoyable MacBook Pro's I've ever owned, and i've had fair few others too!
[doublepost=1535622503][/doublepost]

While I was reading this thread, responding to an iMessage in the quick reply feature, that reply hung and the computer shut off. I was finally able to get it to reboot and see the below log.

This is on a 2018 13 in MacBook Pro and is the second Bridge OS crash I've experienced in the last 8 hours. I posted details on that one in another thread, but seemed to be related to the sleep/wake. Both have occurred after installing yesterday's supplemental update. I don't recall a crash before that supplemental.

Today is 15 days since purchase, so I'm one day past my return window.

Have you tried booting into recovery mode, accessing the secure boot utility and turning off the restrictions? (Any OS and allow boot from 3rd party drives)

I think these are totally unnecessary precautions anyway and we've managed to live with 18 years of OS X without them (plus I need to boot from an external drive quite a lot!) i've heard this can help.
