Pimped some month befor with 16GB (8GB org) RAM (Samsung) and a 1TB SSD (Samsung Evo). Everything works fine. I love mavericks and i haven't issues with 10.9.2 (dont use airplay so often and don't try it with 10.9.2).
So ... a few days ago i got the first error - system crash. this crashes comes more and more and i search for the reason. first i think this is a 10.9.2 issue and so i have reinstalled the 10.9 version (over the 10.9.2) and have updated then to 10.9.1 after the MBP works fine for a few hours. till this time i haven't infos about internal and discred grf card, so i try not the right tests. But can say: even if i use apps like photoshop or canon viewer or look videos or start vmWare with a virtual machine the system hangs up / crashes several times. often i need more than one reboot to restart the MBP.
In summary:
Have frozen display (system should be work), NO GLITCHES, sometimes i have a split window befor it freeze, sometimes not, bluescreen an grayscreen with heavy speed fan. If i reboot i have a grey screen with heavy fan or a normal grey screen while starting with the apple logo and some orange stripes over the screen.
then i read this thread and install yesterday the gfxCardStatus. Choice the internal card and test the system (videos, virtual machine and so on). everything works fine. same test with ext. card failed. so from my point of view the external gpu have an issue. ok - at the evening i close the MBP and the book was slppeing over night. at this morning i open the book, see the login mask, fill out, see the desktop and - system (display?) was frozen. no chance without reboot.
I have test gfxCardStatus again after reboot - choice internal card and - system (or display?) was frozen. no mousepoint after changing the modus. whats that?!
So, i cant use gfxCardStatus - and i have no idea now what i can do. Any idea for my one and only 3.200EUR MacBookPro? Actually i only can use Safari or Outlook. To prevent system crashes. But for this work i can use a windows notebook that only cost 500EUR
Thanks,
Tom
