Hello everybody! I have recently switched (since 2 days) and after investigation in this new world, I have quoted that the window " HELP TO SWITCH FROM WINDOWS TO MACOSX " of the HELP menu continuesly blink as if try to update the windows, or in attempt of display the windows in the infinity. So i have reinstalled the osX which was delivered to me by reformatting beforehand the hard disc because, told me, "it can happend that he system badly installed in factory". But I always have the same problem, so this is not a software problem So i have decided to test the state of the hard disk (that i have thought be responable in the problem) but the program testing it show me that everything is well. So I have decided to execute the TEST APPLE HARDWARE program (touch 'D' maintained in the restart with the CD1 of OSX inserted) which allowed me to test all the internal components of my macbookpro and finally the test finds me that I possess in hardware a NVIDIA GeForce 8600M GT with 256 Mb card :lol: BUT the "ABOUT THIS MAC" window in the of macosX [so with the analysis of my system by software] indicates me he that I possess the version in 128Mo . Before bringing back the macbookpro to the store I wanted to know 1) if the TEST APPLE HARDWARE looked to those who have the same model as me the same result, and 2) If it was possible to keep my macbookpro 2,2g config with the 256Mo graphics card of the 2,4g without that it create a major conflict (type overheats) and if it is possible, what i must do to change the software configuration of macosx to set that I have a 256Mo card indeed??? Lot of thanks by advance for help, and please excuse my poor english sentences quality... i am frenchy user ... Best regards!
