I'm running OSX 10.7.4 on my Macbook Pro.
For reasons I have yet to figure out - every now and then my macbook simply stalls for about 5 seconds.
Sound Stops Playing, Mouse becomes unresponsive, Keyboard, not responding - Apps not processing.
Network is not lost during this - or so it would appear (perhaps my apps reconnect without me knowing about it - i don't know).
I have (and there it happended again ) not yet figured out if its periodical or due to some hardware sensor value or whatever??
It does not appear to be related to any specific application - I have experienced this while using Firefox, Chrome, Safari, Mail, Evernote, Skype, Citrix Receiver/Viewer, VMware Fusion and others.....
Does anybody else experience something similar like this?
