Lion Video Freeze Happening Again with New Mac mini

11/20/2011

I recently replaced my iMac with a new Mac mini, and I had forgotten how annoying the video freeze problems under Lion had been. Today, trying to view a Flash video on a news site, I had a freeze, exactly like what I had with the iMac and Mac OS X 10.7. The Lion updates had resolved the issue with the iMac, but the errors I see with the Mac mini are exactly the same type. Console logs show the following:

11/20/11 1:34:40.000 PM kernel: ** GPU Debug Info Start **
11/20/11 1:34:40.000 PM kernel: 0x00006741

[etc.]

(It’s worth noting that the above messages are almost exactly the same as what I saw on the iMac.)

OK, this is enough. I’m starting to get very frustrated, not only because of this problem, but also because of Apple’s letting me down regarding another problem with the iMac. I’ve very seriously considering doing as some of my friends and colleagues have done and downgrading to Snow Leopard…

Update: It turns out that there is something wrong with the video card – since I get the GPU debug logs in Console, as well as the occasional video artefact – but also, perhaps, a problem with the SSD. Apple is exchanging the Mac mini for a new one, and I should have the replacement in a week. In the mean time, it freezes several times a day…
