MacBook 12in lockup UI freeze (failed to reset GPU)

You are using such a new Mac that I'd recommend you to take it to an Apple Store or reseller to get it repaired or replaced for free, because it is in warranty. That GPU message may indicate that there is a GPU problem, but the Genius will tell you what the problem is.

I'm having the same problem. blueswine: did you ever resolve this?

I've had this happen every couple of weeks, for a total of 6+/-2 times since I bought it. No solution, but rare enough that I've been living with it. I had no bites when I posted the same on macrumors back in May:

http://forums.macrumors.com/threads/2nd-hang-lockup.1883961/

I guess I'm hoping someone else figures it out :-)

Since this issue has happened to me several times, the only patten I can think of: I'm pretty sure I've always been using IntelliJ when it happened. IntelliJ is a Java-based application.

I have two units of the new 2015 MacBook. Both use the same suite of software. One is exhibiting the problematic behavior mentioned in this thread and the other one – not at all. Yesterday I called AppleCare just to let them know that there may be some kind of a bug in GPU drivers etc. (because "may have failed to reset GPU; Ring class found no clearly guilty ring; Ring class found no clearly guilty ring" messages spring up in system log every single time when freeze happens). The consultant I spoke with, advised me to simply reinstall OS X. I am writing this post using the clean OS X installation. Let's see where this will take me... 🙂

To relate to one of the previous posts: I am not using IntelliJ. I do not have Java installed at all.

When using PyCharm, I got freezes sometimes.

Before I using PyCharm, I have never got this kind of freeze on OS X.

PyCharm is a Java based software. I believed this problem is caused by Java.

My OS X version is El Capitan, 10.11 Beta (15A279b)

Same issue on GM 10.11 (15A282b), while using PyCharm

I found a workaround this issue.

set & use default java version 1.6 to launch java base applications (android studio, ...)

(java 1.6 for mac legacy is distributed by apple)

you can easily search the web page how you can set default java to 1.6 on mac

java 1.6 is just using to launch the apps.

therefore you can use java 1.7, 1.8 in your development projects.

Blueswine,

Have you resolved your issue? I have the same issue as yours.

bougth the macbook 12 in July and so far have encountered this problem twice. All with the IDE development kits from jetbrain(one for rubymine and one for webstorm)

can't figure out if this is about java or jetbrain's. or maybe some kind of flaws from Apple.

After months of being fine, it's happened to me twice today. I upgraded to 10.11.1. And, for me it's still 100% of the time when I'm interacting with IntelliJ.

I encountered this issue everyday - at least 2 times, at most 6 or more times. I am also using Android Studio more than 10 hours everyday. At first I guessed the high CPU usage by Android Studio's Code Insight would lead to the freezing. I tried to switch to power save mode for Android Studio, but it did not work. And sometimes I'm not using the Android Studio, just surfing the web.

I also tried the CPU and GPU stress tools. For hours this issue is not coming when running these stressing tools.

For this weird issue, I guess it might be some kernel driver bug in OS-X itself; Or it might be the CPU hardware stability issue since my MacBook 12 model is configured to the 1.3GHz CPU model. Since Intel only released publicly the 1.2GHz Core-M CPU model, Apple might overclock it.

For me, the magic combination is both high CPU and a Java application. I forgot that I changed my Mail integration with Google Apps today, and Mail was pegging the CPU downloading and indexing in the background. I didn't get the lockup until I started to use IntelliJ. I stopped getting the lockups (2 within the span of 30 minutes!) when I quit Mail.

I have the lowly 1.1GHz, so I don't think it's the 1.3.

I have resolved this issue!!!

This issue is reproducing when a java based application(intelliJ, android studio,..) runs on Java1.7, 1.8.

If you want to resolve this issue (only workaround), an intelliJ(android studio) must be running on Java1.6.

This is an only way to resolve the problem at this time.

p.s.

I suppose this issue might come from a rendering feature (java1.6 vs newer version)

"On Mac OSX, the default version we are using to run the IDE (not to compile your code) is Java 6. This is primarily because the font rendering on Java 6 has full subpixel LCD antialiasing, whereas Java 7 and 8 does not."
