Cold restarts after 10.10.3 update.

Cold restarts after 10.10.3 update.


Hi,


Ever since the 10.10.3 update I am experiencing two problems on my mac mini. I am not entirely sure that they are related to the update but since I haven’t changed anything (hardware or software) on my mac, I can only assume that the update probably triggered the issues.


The first problem is that every now and then I get a bunch of pixels flickering on some random position of my screen. Another user reported the exact same error and posted a video here: https://www.facebook.com/georgetasioulis/videos/10203713632115564/ Once I drag a window over these pixels, the problem is gone.


The second and more major problem is that I get random cold restarts. It could be 5 minutes since I booted my mac or even a day after. There is no specific app that I’m running when the mac restarts. In other words I can’t seem to find a pattern on when this happens.


After reading many forum posts I ended up doing a clean installation of Yosemite and started installing everything from scratch. After a while the same thing happened. I noticed that some “power users” can make sense of the kernel panic logs so here is my latest one:

I would really appreciate if someone could point me to the right direction in order to figure out what to do next. My spec is a mac mini (late 2012) 2.3GHz i7 with 16GB RAM from Crucial and a Corsair SSD Force 3 240GB. It is connected to an Apple Thunderbolt display with only one peripheral: a Logitech Anywhere MX mouse.


One last thing… the above kernel crash log is kinda rare. Most of them have this:


Kernel Extensions in backtrace:

Not sure if this helps but “com.apple.iokit.IOACPIFamily” is mentioned most of the times.

It seems that third party apps that place an animated icon in the top right menu bar may cause these problems. In my case it was MenuMeters (which is plugin to SystemUIServer). After removing it things seems to be back to normal here, no flickering, crashes or jerky trackpad for week. I believe Little Snitch also has such an icon?

Hmm - maybe we are onto something here. The few kernel panic reports I got, sometimes had iStat Menus listed as the cause. And this would explain why mostly tinkers are affected. Nevertheless, even if this is the cause - it mustn't lead to a kernel panic in a modern OS.


Do you use the Dark Menubar?

how do you get the cause in the report?

is the line stating: "BSD process name corresponding to current thread" ?


Yes I use the dark menubar.

I'm having the same issue with 10.10.3 with restarts. Thread here: iTunes crashes Yosemite 10.10.3 to black screen


I'm running a Mac Pro (Late 2013) with 1TB SSD and 2 AMD D700 Firepro.


My issue is similar that it happens with different software (I can regularly trigger it by opening iTunes). My Mac freezes the cursor and completely stops responding and then cold reboots after about 10 seconds and a black screen.


I'm going to try to roll back to 10.10.2 this weekend to see if that helps.


It does seem to be a hardware issue. Depending on the type of hardware you have. SSD might be a common hardware theme with those of us who have the crashing.

Due to the fact that many people started to get these stability issues and same flickering behavior right after 10.10.3, it really seems to be a software fault (of course for one or two people it might be a hardware fault after all).

Can only speak for me, but I've checked my hardware with AHT, SMART Utility etc. and it is just fine (and downgrading to 10.10.2 leads to a rock solid system again).


Also Apple released a Final Cut Pro update just a few days ago, which also fixes a "crash on startup" bug - so they seem to have some stability issues on the software site in general at the moment. 🙂

May 16, 2015 7:42 AM in response to Panagiotis Tsamoudakis

The restarts I could solved in this way: Go to System Disk System : / System / Library / Extensions - here you find the kext-Files, sort it by Date, look at all kext Files older than 2014: this could be a part of the problem. I found here old kext files from 2010 and older. I make a Copy of thes files, deinstall it, make a reboot an no more cold restarts. But beware: kext Files Could be nessesary for you system. Changes at your own risk.

Deleting the Ambrosia and Dymo.kexts can a good idea if they are old and not from Apple - but for example: the AppleMobileDevice.kext is essential for many iOS devices to work correctly with the Mac (and on my Mac it is from September 2014) ... not clever to delete it.

May 16, 2015 8:06 AM in response to Larsen2k4

Therefore I make a copy of all kext files before I remove them. The BJUSBMP.kext and BJUSBLoad.kext are old one from my Canon PIXMA Printer, After deletion I install the actual Driver for OS 10.10 from Canon Site.


The Accusys6xxx was the oldest one, I dont no, what it do.


If you have an ATTO Extension Card, look at ATTO Website for actual driver, but my mac mini has definitly no ATTO Extension card in it.


The JMicronATA.kext is old too, I found no new one, but my hards disks works after deletion, so I donts need it.

And yes, I have no old Apple mobile Device. And I wrote: But beware: kext Files Could be nessesary for you system. Changes at your own risk.

May 16, 2015 8:28 AM in response to Larsen2k4

This tip is dangerous for most users.


Although I did a clean install with 10.10.3 I found a lot of apple-.kexts older than 2015 and a couple of kexts for graphic cards I do not own. If Apple wants those files on my SSD, I leave them there.


A few days ago I tried to delete some safari plugins by simply deleting them (Adobe for example). They were already deactivated within safari. Made my MBA having hiccups until I put all of them back into their folders. Which turned out to be a real pain.


I'd still advise everyone to use a different adapter and/or to do a safe start without having an external monitor plugged in and/or upgrade to the latest 10.10.4 beta if possible.


Which one of you is using some kind of maintenance-program or anti-malware program? I don't but those could create additional problems.


I deleted iStat menus as I had the feeling it didn't provide proper readings anyway. Had funny visual artifacts on my screen right after that. Anyone else experienced this?

May 16, 2015 8:32 AM in response to kadokado

kadokado, hi.


Thanks for share your information, but...

I did a fresh Yosemite 10.10.2 install on a spare external HD... Then updated it to 10.10.3

All problems returned after 10.10.3 (kernel panics, blinking bars)..


There was no chance having older kext files that 2014, except those who own Apple put it there.

I think we are trying to solve problems created by an update, in a "M$" way, when in a not remote past, when users like me and thousand ones, did fancy changes to the system trying to bypass bugs in the M$OS.
I want to believe that Apple is better than that.

Regards

Larsen - I do agree with you and it does seem to be the software update 10.10.3 that caused the problem. I was thinking that it might also be the case that users with a certain hardware configuration are affected - not all. But I guess this is probably true of most bugs.


I hope we can all figure this thing out soon! 😎


I was going to do some tests today - including trying to roll back to 10.10.2. Then upgrade software one at a time until the problem starts.


I'm not sure I feel comfortable deleting (moving) those Kernel Text files. I am an advanced user but I don't know the entire interworking of the file system.


Thanks again for the help.

Cheers!

May 16, 2015 9:25 AM in response to BG2k

@BG2k


You misunderstand me. I could only say, what was the solution on my mac mini, this not mean, that this is the solution for all users, I could stabilize two apple computers in this way, but this not mean, that apple makes all good, if 10.10.2 makes not restart trouble and 10.10.3 do of cource there is an connection with the update. And the flickering squares I could not remove with 10.10.3 on my macmini, my iMac did not have the blinking squares, so I think there could be an conncection to the other graphic card.


---

And if an error occurs exacly after an system update my first idea is not an hardware error, although the mac mini was hotter than normal after update, which could make hardware problems, BUT: The flickering stops immediately, if I change the ICC Profile (but comes back), so I think, its an software problem.

---

And @BG2k: Writing million of rows code without problems is more complicated, as you think, sometimes little reasons has fatal consequences for some user. Be a programmer an you understand, what I mean, this problem has MS and Apple and all other system developer in the same way.

I would also prefer a stable system, but the errors are determined not installed intentionally.

May 16, 2015 9:38 AM in response to Carl__R

Ugh. Had 8 little black boxes flickering on the upper left corner of my screen...the flickering started, when I ticked the menu bar, stopped, when accessing any folder on screen and started again, when accessing dock and/or menu bar. Finally stopped after a few minutes.


The only thing running right now is chrome with a flash video and mail and safari and LS network monitor.

Cold restarts after 10.10.3 update.
