Jeordanis Posted February 2, 2014 Share Posted February 2, 2014 Hello I am new to these forums. I managed to install 10.9 Mavericks and for a few hours the installation was perfect, i install some kext for audio and ethernet, install skype and configure my email account, install adobe flash, then while surfing on Safarie the system freezes, after that I could not restart the system, after the apple logo screen goes blank with the cursor in the center. I tried to boot the system by USB Clover and got the same result, I tried to boot in safe mode and the same thing happens. I went back to format and perform the installation again, it was perfect for a day, again install the kexts, wacom drivers for the graphics tablet, some programs and again the system freezes while surfing Finder. I should also mention that i only use a 15gb MBR partition and have dualboot with windows 8.1. Anyone have any idea what 's going on? I have not found anything like that on these forums. My hardware is: Motherboard MSI Z87 -G45 Gaming Intel 4770K Ssd Kingston Hyperx 3K 8G Ram Intel video HD4600 Thanks in advance! Quote Link to comment Share on other sites More sharing options...
