Hello,

I had 2 freezes in 3 days, when a freeze occurs:

- HDD/SSD led full ON (not blincking)
- Cannot move mouse, system responds to nothing

Nothing is logged in system.log

Occurs on both 120GB and 500GB SSD.

Occurs once in 10-12 hours.. Cannot say exactly how often..

First time:

When I was typing

Second time:

I was away from computer, when returned screen was frozen...



Formatted as GUID, no APFS.

Any ideas?
 
I have the same problem. It freeze more frequently when I copy large amount of files from one drive to another.
It did not happen in Sierra. It just happen after I update my system to High Sierra.
 
I had the same problem with my asus p7p55d system. If you have an option in your bios called advanced link power management make sure to disable that. Some people report that solves the problem. I do not have that option on my system.

There are some ICH10 kext patches that you can do in clover and since I started using those a week ago I've had no freezes. I'm not at home right now so I can't post the exact patches I used. Someone else may be able to post them.

EDIT: Had a copy of my config.plist on google drive. Since adding these 3 patches I've had no freezes.

Thank you very much for your tips. The board I am having problem with is Gigabyte H67MA-USB3 B3. I don't know whether it is using ICH10 or not.
I have applied your patches to see if it helps thru.
Hope the patches solved my problem.
THanks
 
Update:
The patch suggested by eradicator006 solved my problem that
When system booting up, the notification pops up saying one of my harddrive is uninitialized.
THe drive now showing up correctly and I am now not facing any crash yet after applying the patch.

Thank you very much.

UPDATE 2018-01-02
Confirmed fixed the random crashing problem with a test of whole day using the method of eradicator006.
Thank you very much eradicator006.

You are awesome!
Thanks for this solution - it solves my random freezes and lags from the first install of 10.13))
I think that it was GFX issue - the logs were empty about HDD errors!
Thank you very much
 
Hi all,
I'm trying to apply these 3 patches but am having problems, should I use Clover or something like Plistedit to add them to my config file?

Thanks in advance.

Thanks, it works!!!
 
Is this patch works on Mojave and Catalina as well?

I am having problems with those above OSX.

works well in High Sierra btw.
 
I'm trying it just now on Catalina.

I suffered of these random hard freezes from High Sierra Upgrade. Let's see if it works.

Anyway thanks eradicator006

Update: I applied ICH10 patches but it didn't work. Then, as suggested in another thread, I changed system definition from iMac 14,2 to 14,1.

System is up by 6 hours.. I know that it could't be judged as resolutive, but for my case is really good.
I will update statistic if something changes.

Another update: I came back to home and I found the computer switched off.. It could be another problem related to power management or to sleep. Let's see if I'll experience freezing again..
