zero667 Posted March 10, 2016 Share Posted March 10, 2016 Hi guys, I'm stuck for a while now with a strange problem. I have an older Installation running Mavericks, but i can't boot this anymore. Chimera is loading properly but when i select my Mavericks install, it loads the kexts and after the line where the CPU information comes it just reboots. Looks like: CPU Intel Core i5 2500K 3,3GHz .... ... ... So there are just lines over about half of the screen. I tried clover with a usb thumb drive and El Capitan on it, but it's nearly the same. After I select the OSX Installer the screen goes black, it prints just +++++++++++++++++++++++++++++++++ then reboots immediately. I tried also a Yosemite/Chimera installation, but then there's the same issue as i have with my current Mavericks installation. I already tried several things: tested nearly every possible bootflag combination, including nv_disable=1,npci=0x2000,-xcpm,cpus=1,kext-dev-mode=1,nv_drv=1,GraphicsEnabler=No,-KernelPM patched the kernel with the Haswell Patch for early reboots on Haswell CPUs (although i know i don't have a haswell) for clover i tried different drivers and kexts, removed VBoxHfs with HFSPlus, tried both OsxAptioFixDrv/OsxAptioFixDrv2 tried different BIOS settings (tested nearly every relevant option on and off) reduced RAM to just one stick, removed all irrelevant HDDs But all i try just brings me back to the early reboot issue. One strange thing to note is, i have my current chimera on a different HDD, not on the EVO where OSX is installed. When i unplug this particular HDD, neither chimera nor clover will boot. Please help me guys, i'm out of ideas right now. Link to comment Share on other sites More sharing options...
