High Sierra freeze

Two things to test,

—Start in SafeBoot mode and see if it is isolated to extensions in your User

SafeBoot https://support.apple.com/en-us/HT201262

—open a guest account and see if the problem is universal

macOS Sierra: Set up users, guests, and groups on your Mac

With this information you can figure a way forward.

I am having the same issue. Previously the system worked perfectly. Then after updating to High Sierra it froze twice within the span of a couple days: once when I was playing a game from an external hard drive, another time when I was watching a stream on Twitch.

In the process of restoring from a Time Machine backup of MacOS Sierra. Will see if that solves it, then update. I am expecting it will. I don’t have the time to troubleshoot all the console logs and such. Will leave that to Apple.

Report it to them the next time it happens. That‘s what I am going to do and that’s what all of us should do, really, in order to maximize the chances of this getting fixed promptly. The next time it happens, make a note of the time. Then after you restart, pull all your Console logs from that time and send them to Apple along with a description of the problem here: https://developer.apple.com/bug-reporting/

Since you had the same problem before upgrading to High Sierra your problem is not the same as the OP's.

Therefore, download and run Etrecheck. Copy and paste the results into your reply. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.

Or better yet start a new topic with detailed info on your problem and the results of the Etrecheck report.

Same. Suddenly everything freezes, fan goes to max speed and a reboot is the only thing that will sort it out. Haven't been able to pin down the cause. Thought it might have been Safari, but switched to Opera and problem still remains. So many bugs with this OS, (preview is a disaster!) I'm gutted I 'upgraged'.

"minor update" LOL!

Thanks for the article--good read. However, I have no evidence or reason to believe that the freezes I was experiencing while using High Sierra were the result of any kind of hack of my EFI. I think that in all likelihood, High Sierra just has a few lingering kinks that need to be worked out for certain system configurations. Rather than waiting for Apple to perhaps patch these at some future date, I opted instead to start fresh with a clean install of an older, less demanding OS. For me and my 2012 iMac, at any rate, this has proven to be a great workaround.

I have, however, submitted all my console logs and crash reports to Apple through the developer bug reporter, along with a description of what happened when I was running High Sierra, so hopefully they will be looking into the freezing issue(s) soon.

I have the same problem. Started immediately after I upgraded to High Sierra. I reset the ram, started up in safe mode, tried using the guest account, upgraded and reinstalled my apps... aaaand nothing worked. Thanks to the person who posted that downgrading didn't resolve the issue, and to the other person who suggested that the firmware upgrade, that's part of the High Sierra OS upgrade, may be part of the reason why the downgrade didn't work. That saved me a lot of time downgrading my machine.

It seems to happen on a wide variety of Macs and the newer ones appear to be affected as well. My MacBook pro is a 2013 model, and prerequisites for High Sierra say that it's supported.

So I guess now we wait and hopefully enough of us post on here that Apples takes note of the issue.

Apple: You could at least acknowledge that there is an issue. We promise to still to love you..

Hey all! here is an interesting tidbit of info. I installed the High Sierra 10.13Beta (17A362a) on a Mid-2010 Mac mini with 8 GB of RAM and a 512 SSD replacement for the original HDD. This Mac mini is hooked up to a TV and used as a media server in my house. using a terminal window, uptime states that it has been up and running for over 30 days, 8 hours, and 22 minutes... All of the laptops that I have installed High Sierra on (10.13 release and developer Beta) are all crashing... Now in the process of reverting back to clean install of Sierra on my 2014 MacBook Pro+Retina...

Yesterday I successfully installed High Sierra on a MBPro 17inch (mid 2010) after it failed the first install the day before due to a firmware version issue. Miraculously the next day (yesterday) I called in an Apple Support ticket and they had me retry it. Why this would work was beyond me but I figured I do the install again. Took forever and flashed through several (and different) Apple with status bar screens (guessing firmware and software updates in succession).

It booted once successfully - second startup today and it froze on the Apple status bar boot up screen. The processor got real hot (like the burn-in software would do). I had to shut it down for a half hour to cool it off. Still does the same thing and gets real hot. This thing worked great the day before on 10.12 and now its tanked. 😢

Did the startup holding 'D' to do an internet recovery but that throws a -3403D (hardware issue) code.

I'd say Apple was hacked (maybe from the inside) and all their install base that tries to go to this version is hosed.

I don't see an easy fix for this issue as the firmware is new for High Sierra - can you see them shipping out repair CDs!!😁

I have 3 dead computers now after updating to Sierra and High sierra.

A macbook air 13" mid 2013, a macbook pro 13" 2011, a macbook pro 15" 2011. 3 of them died in 2 weeks of time after updating their OS X. The symptoms were :

- Macbook air battery consumption increased and battery lasted 40% less. The fans were running more fast and the computer was very hot. One night it died while listenint soundcloud music, reset itself and the logic board died. Took it to service, they said they need to replace the logic board.

- After 3 days, macbook pro 13" showed some video glitches (yellow-black bars) on the screen, started running very hot and bum, it died. Took it to service, they said it requires a logic board replacement.

- After another 7 days, this time macbook pro15" reset itself while using autocad. Then the OS couldn't start again, the computer entered a loop mode, after turning on, it starts to load OS, then right before OS starts it reboots and starts again. There were some horizontal lines on the screen (not straight lines). And the computer was running much hotter than before I update it to High Sierra. Took it to Genius, they said this is a known issue with Macbook Pro 15" 2011 model and there was a recall program which ended on 31 Dec. 2016. So I missed that one, and they offered me logic board replacement around 800 USD.

Then I came here to check whether people are having similar issues with latest OS updates since 3 computer dying in 2 weeks can't be a coincidence.

Will be monitoring the discussion boards more about this issue and I will file a complaint if there are more instances of this issue. I totally feel like there is some big issue with latest OS X.

I am having this same freezing problem on cylindrical Mac Pro 6-core with 16 GB. I was working fine before updating to High Sierra. The update froze and required a hard reset. After that it started freezing up periodically. I seems to happen if I leave the machine running, when I come back it's frozen. However, it does often happen while using the computer as well.

I started to get the feeling it had to do with Safari, so I started using Chrome instead and the freezes stopped and I thought the problem was solved but today it froze using Chrome so that might not be cause and effect.

I've done PRAM reset and that had no impact. I ran activity monitor for a long time and while that was running I didn't see any out of the ordinary ram or CPU usage. In a way it seems that running Activity Monitor let me going much longer before a crash.

Anyway, this seems to be happening on a wide variety of Mac's so I hope Apple is working on it. I don't plan to reinstall Sierra just yet. I have shifted over to using my MacBook Airfor most things while waiting for an update.

I found something that's guaranteed to lock up my system 100% of the time

MBP 2017, max hardware config, dual external displays

In Adobe Premiere CC 2018, if I apply the "morph" transition, it takes some time to render in the background, when it completes, if the playhead passes over the transition, the system panics and I have to force shutdown via the power key.

Sometimes when my machine boots from a panic, this is the result:
