The issue I've had is from not being able to use keyboard or mouse entry for some random (3-5 seconds?) amount of time. Anyone else seen that? rMBP, fwiw.

I began experiencing this problem on my mid-2008 MBP late last year. More recently, I've found that slipping a piece of paper between the battery and the golden electrical strip helps a lot.

I have no idea if it's related, buy my mouse cursor sometimes freezes on a 2011 iMac running Lion.

Yes. Same here. It freezes and while I can type a little, it ends up "liiiiiiik tttttiis". Those freezes got a lot rarer after I disabled the dynamic pager [1]. I have only experienced it once since then. I have had vm_stat and iostat running constantly to see if I can catch any metrics when it happens, but nothing stands out. It's not related to excessive I/O or swapping. [1] https://news.ycombinator.com/item?id=5626835 https://news.ycombinator.com/item?id=5626835

I'm seeing the same thing. This is my first real Mac experience, got it from/for work, wasn't sure if something like this was "normal". (I'm a long-time Linux user, so I'm used to putting up with a lot of bullshit from my desktop.) I've found a handful of forum posts and support requests, but no solution other than "it's probably a hardware defect and you should return it".

Definitely. I also lose the keyboard at the same time too though, so it's potentially a USB issue as well. Doesn't happen frequently enough that I'm able to work out exactly what causes it.

Yes, this happens to me too but only under certain circumstances. It happens all the time if I have an external keyboard plugged in and try to use the built-in keyboard or trackpad. It will often be non-responsive to input for about 5 seconds. Once both the keyboard and trackpad completely stopped working and I had to reboot (using the attached external keyboard). I noticed some USB errors in console once when this happened but didn't investigate. I've also seen this when it's asleep and I try to wake it up. Often it will take 5 sec or more to respond and wake up.

Happens to me as well on a 2011 15" MBP running 10.8.3. I haven't been able to pin it down but it's really annoying sometimes.

I've had that too, but when it eventually comes back (~10 seconds) I get about 100 repetitions of the last key I pressed. Mid-2009 MacBook pro.

I occasionally get into a state in ML where the mouse click events stop working (and the Cmd-Tab UI doesn't show up). This persists until I kill "Dock". Then the mouse starts working again (and the desktop resets itself), but the dock and Cmd-Tab UI don't come back. (Cmd-Tab works, but doesn't display the UI.) I never figured out the magic thing to kill to fix this, and end up rebooting. (This hasn't recurred since the latest point release, so it may be fixed now.)
