Q: WindowServer[]: GPU Driver appears to be hung (over 5 continuous seconds of unreadiness)
Hi,
i have a huge problem with my < 1 Year old iMac 5K. It seams it is not capable of running creative tools. At least this is the statement the Apple Reseller gave me as the excuse followed by, i have to wait until Apple update its driver and hope the problem will disappear.
But one after another. I Bought this iMac i a configuration with the better CPU available (i7) and 16GB of RAM in April last year. When i asked if the less perform graphic card is enough to run oll application but games, they ensured me that this is the case. Then the whole year long there was seldom behavior with this mac, since after a while it started to hang for a period of at the beginning few seconds and after a while a few more until it become completely unusable due to high frequency of freezes. Those freezes was mostly gone, when the focus of the application was changed (cmd + tab), but come again over and over.
First thing i did, i though that thing is broken and got a new logic board installed, but the problem ramains.
After all i discovered that the log is full of statements like:
WindowServer[]: GPU Driver appears to be hung (over 5 continuous seconds of unreadiness)
while the application is frozen. So i brought the iMac back to the reseller. Just today they called me and told me that this problem is related to ALL creative tools like Photoshop but also music programs like Ableton and even Logic X! They told me that i will have to wait until Apple comes up with a new Logic Board driver which hopefully solves the problem. I mean they literally confirmed that the iMac 5K is not not capable of running any creative Application at the moment for a longer while.
My question is, what should people like me do, when the only purpose being this computer was creative tools. Is there a program to switch to a different machine like MacBook or Mac Pro or are the iMacs postum declared as not usable for creativity and the buyers let alone in the rain?
iMac with Retina 5K display, OS X El Capitan (10.11.3), Logic X

I had a kind of break thru the other evening. I've been told by Apple to remove all parts which do not come from Apple and see if the problem still occurs. The only part which was not original Apple hardware (beside the thunderbold audio interface) was the additional RAM build in by the Apple retailer directly. So i never had a chance to compare the iMac with and without additional RAM. Once it get removed the Problem
disappeared nearly completely! Before the freezes was multiple times a minute after the removal of the additional Block i had only one short freeze with the log error massage: WindowServer: GPU Driver appears to be hung
