Why does my Macbook pro keyboard and trackpad randomly become unresponsive forcing restart in OSX Mavericks?

Very similarly.

Mac Mini late 2012. i7 CPU, 16GB ram. 12GB unused.

After installing Mavericks, it seems to grind my system to a halt. It is still running (I can move the cursor and activity monitor updates processes) but every application I try to launch results in a colorful waiting sign. It even can take a minute or more before an application shows "any" sign of starting.

I tried to open a terminal session (so I could manually kill a process) but the terminal session did not even process. It timed out after 5 minutes.

Acitivity monitor shows 90-95% idle and I have no idea what's causing it.

I have already rebuild disk and reset permissions (all seemed fine) 3 times.

I've rebooted over 8 times since last night. I cannot use my Mac anymore reliably.

Please help.

Same problem on iMac 2011, sometimes trackpad stops working and I need to attach a mouse to continue working, after some minutes it restarts by itself.

Also at boot from scratch it connects keyboard and trackpad some seconds after login screen appears.

I do want to clarify that in my case my keyboard or mouse DO remain responsive. It's just like Mac OS X is running at 1% of the speed.

CPU shows about 90% idle though.

I just came back home and even logging in did not complete after 12 minutes so I had to physically reboot AGAIN. More than 12 times since yesterday.

All apps have been updated to the latest versions with no difference.

Same problem for my macbook pro after upgrading to 10.9

But my case is little bit different my trackpad was working after the upgrade process done but when I shutdown the laptop and powered it on the clicking function in the trackpad and the magic mouse is not working...

The same failure steps as MS did before

Same problem here but with an external mouse and keyboard MBP is working well. Several apps crashing either, even the upgraded keynote by Apple itself!! It just does not works anymore, I'm back in the days of restartig a computer for no reason like some windows user.

Same problem here with a 2011 MacBookAir

Cannot predict when system will crash.....sometimes after putting the MBA to sleep and the login screen doesn't come back, and sometimes right after booting up the screen just freezes, even worse is when I try to do very simple things like browsing youtube or facebook the colorful loading icon appears, then after 10sec of so the whole thing became unresponsive. When it is working most of the time the heat sink fan is running like crazy while nothing really demanding is running, and the status monitor indicates that CPU reaches a temperature of 80+ C.

Before upgrading to Maverick I never need to force shut my MBA, nor I never worry about not able to login back after putting it to sleep. Now I feel like using a PC in my old days with the crappy Windows OS.

Same here - I have a 15" Early 2008 Macbook Pro and since the upgrade to Mavericks my touchpad and keyboard randomly stopped working. But when I plug in my Logitech Mice this one works fine.

Hi everyone,

i have a Macbook Pro 13" Mid 2012 & OS X 10.9.1 and the same problem as described.

Seems there is a Bugfix for Macbook with Retina Display only.

Does anyone know what to do ?
