System freezes since High Sierra

Imo take your computer into an AAPL store, see a genius, the more people that make APPL aware of this problem the better, and an eventual solution arising. I had the slowing down grey screen, eventually reached the end of the install/login, fan whirring away, and never managed to open the login page. Could only access via command/r disk utility which did not solve the problem. Check there though your install log, it did for me provide a lead to the problem issue and a solution. Even uploaded a replacement copy of HS via internet but that also did not open. At least you have a backup so imo try getting the genius to do a disk cleanup and an install of Sierra followed by recovery of your backup data. Good luck!

Just to add to what everyone else is experiencing: I am experiencing the same freezes on a MacPro with 8 cores, 64GB of memory, four 27" monitors and High Sierra 10.13.2 installed. Incredibly annoying and really unacceptable on a very expensive machine!!! I tried to switch the monitor sleep function off (System Preferences->Energy Saver->Turn display off after: never) and switch the screen savers on instead (System Preferences->Desktop & Screen Saver). I used the Flurry screen saver and ticked "Show with clock". I normally work until around 10:30pm European time when the US markets close and I can see the system freezes around 4am (so about 5-6 hours later) as the clock has stopped but is still displayed on the monitors. I don't claim to be an expert, but if the system can "work itself" into a freeze then perhaps it is a memory leak from an app (although must be a pretty serious leak with 64GB of RAM) or a periodic service that is catastrophically malfunctioning. Whatever it is, Apple really should get their act together and fix this.

This is clearly a widespread problem.

Next step will a to take it to Macworld , macrumors , etc. that puts the problem in front of many more eyes and and then will get attention.

I think Inniss time to increase the volume on this

There's already a discussion on Macrumors https://forums.macrumors.com/threads/10-13-3-worst-update-ever.2096210/reply?quo te=25641604

Yesterday, nVidia has installed a new driver - 378.10.0.10.10.254.104. Chrome started working a bit more responsive, but still not up to Sierra speed.

PrebenBN, bottom line is the last sentence of your posting: "Whatever it is, Apple really should get their act together and fix this." I can't remember a time when I've been so discouraged, disheartened, and disappointed in a company--especially Apple!

Update 17 Jan 2018 08:42am CET: For reasons unknown, I have not had a freeze in two days. Instead of the usual frozen clock on the screen in the morning, the screen saver is running and I can log in as usual. Since my original posting on January 11, I have only updated the following: macOS High Sierra 10.13.2 Supplemental Update (I guess this was the CPU security fix), HP Printer Software version 5.1 and Telegram version 3.7.3. I also deleted and re-added my HP printer under System Preferences->Printers and Scanners and unplugged an external USB diskstation. I doubt any of these things would have fixed the problem, but for whatever reason, no freezes the last two days. I'll try to switch the Energy Saver back on so the displays are turned off after 20 minutes and switch the screen saver off.

Same for me! I did go into an Apple Genius bar, but the problem had disappeared a day or two earlier. The tech guy couldn't find anything wrong or explain why the issue happened. Fingers crossed that it stays resolved.

Update 18 January 2018 4pm CET: As others have reported, the problem has gone away. I switched the monitor sleep function back on and all is working. No freezes overnight or during breaks. Very odd (but also very, very nice). I’ll report back if it reoccurs.

I'm ready for Apple to make good on my Apple Care and provide me a new MacBook Pro. I began with freezing problems the first week I had it, went to the Genius Bar and was told to stop using CNN as my homepage since that's the only time the freezing occurred--when I was on CNN's page. I also was concerned about the fan motor of my MacBook racing and sounding like the entire laptop was about to take off whenever I used Lightroom and was told it was supposed to do that. Now with the High Sierra upgrade and freezing issues whenever it goes into sleep mode, I have reached my limit. I don't know if it's the MacBook Pro, the upgrade to High Sierra, or what. All I know is that I'm a really unhappy Apple user, and I've been an Apple user since 1989.

Hi,

I have been following this and another post (called High Sierra Freeze) about this problem that I am also suffering (Macbook Air mid/2012).

This is me being a bit paranoid but I noticed that my system seemed to be working fine around the 16th and 17th January but when I switched on the machine on the 18th it had come back (I am not completely sure about the times but I would say it definitely worked well all day on the 16th and in the morning on the 17th). A few people commented on the 17th that the problem was sorted. It would be interesting to know if the problem did come back for them.

By the way, did anyone experience any freezes before updating to High Sierra? Mine started a bit earlier, around the time of the latest Sierra update (but didn't happen very often at that point).

After a visit to the Apple Store last week I have now switched back to Sierra (for the second time, the first time I reinstalled Sierra I upgraded to High Sierra immediately and my computer became almost unusable) but now the freezes happen all the time, exactly the same as with High Sierra.

Well I have not had the freezing issue of late. I haven't been running the screensaver or any virtual machines.

In place of the freezes I now have random user logouts. These are not to be confused with reboots. I just log back in again and everything I had spent is now closed.

I am moving back to Sierra. Maybe that will stop this issue.

Apple has to be aware of this.

I'm running a 27" iMac (Late 2012) with fully updated High Sierra. My system was rock stable for the first five years. Since the High Sierra update, I'm getting sporadic lockups where only the mouse is responsive and the only recourse is to reboot.

In my case, this is not related to screen savers or power saving mode. It happens when I'm actively using the machine. I could be in the middle of typing a paragraph and it freezes.

I did a clean install last week, hoping that would solve the problem, but it persists.

I keep hoping an update will solve this.

I was having the same problem on a Macbook Pro late-2011. Everything was perfectly fine, then I finally gave in to the constant "Update your software" messages, after asking to be reminded the next day for a couple weeks. High Sierra was installed.

Then it begin freezing at random times, sometimes I used the mac for a good 10 hours without an issue, other times it froze just a couple minutes after restarting.

Mouse would still move, sound would still play, but otherwise, the system was completely unresponsive.

I decided that I should try to fix this issue, people suggested clearing SMC and PRAM, both didn't have any effect. Then I heard some people saying that reinstalling the system could fix it, so I decided to give it a try.

The installation never got past 50%, it just froze on install. I left the Macbook there, thinking it could be just taking a long while, but after 24 hours without any improvement, I realized it had frozen again.

So now I'm left with a expensive brick, can't use my macbook, can't get into it cause the install process begun, but won't finish. I use my macbook for work, so I had to buy a new notebook just because High Sierra decided to break my otherwise perfectly fine system.

What do I do now?

Update on my late 2015 27" iMac which WAS freezing horribly on a regular basis. It occurred to me that maybe the format that all my external HDD's were set up might be an issue. So I reformatted all to the new APFS and guess what, no more freezing not since last week. It was a hassle for sure, backing everything up off each HDD and then reformatting and recopying everything over, but its done the trick for sure. Hope this helps

I never use external drives. The only storage I ever mount is an external FreeNAS server connected via afp://

My lockups are relatively infrequent, perhaps once or twice per week, but contrasted against five years of never having the system freeze, it's a major concern. I run numerous virtual machines as guests under VMware Fusion. I'm just waiting for the time when one of those is going to be corrupted by the freeze.
