Time Machine Backup causes system crash ...

Question

After installing Mavericks my iMac 27" was very instable. Every now and then I noticed the spinning wheel and then step by step all functions were shutting down: 1. no menues, 2. no shortcuts, 3. no window change and so on. At the very end only swiping between desktops was possible. Tonight I just let him do hoping this will be fixed. I the morning I noticed the login screen, but without any function.
Actually I assume that the Time Machine Backup causes the problem! I switched it off about two hours ago and the system works perfectly until now.
I am using a TC 1. Gen. with Firmware Version 7.6.4 and Air-Port utility Version 6.3.2.
Routing and WIFI is both turned off on TC, I only use the TC for TM Backup and iPhoto/iTunes Media in a LAN.

Your problem is apparently caused by a third-party system modification. Reboot as usual (not in safe mode) if you haven't already done so. Launch the Terminal application, copy or drag -- do not type -- the line of text below into the window, and press return:
kextstat -kl | awk ' !/apple/ { print $6 } '
Post the lines of output (if any) that appear below what you just entered (the text, please, not a screenshot.)
Next, do the same thing with this line:
sudo launchctl list | sed 1d | awk ' !/0x|apple|com\.vix|edu\.|org\./ { print $3 } '
That's one line, not two. You'll be prompted for your login password, which won't be displayed when you type it. You may get a one-time warning not to screw up. You don't need to post the warning.
Next, this command:
launchctl list | sed 1d | awk ' !/0x|apple|edu\.|org\./ { print $3 } '
Again, one line. Finally, one more:
ls -1 /Library/{InputManagers,StartupItems}
Remember, this is all drag-and-drop or copy-and-paste, whichever you prefer -- no typing, except your password.
