alexander5230 Posted December 13, 2016 Share Posted December 13, 2016 Hi people! I'm trying to install macOS Sierra on a Dell Optiplex 380. It was perfectly running on OS X Lion until last month. I created a bootable USB of sierra (downloaded from AppStore), but when I try to boot for the installation I have a kernel panic. How can I resolve this issue? I used "dart=0 graphicsenabler=yes -v" as bootflags on clover. There's my specs CPU: Intel Pentium E5800 3.20GHz RAM: 2GB DDR3 (for now, hope to upgrade to 6GB in 2017) HDD: 250GB seagate GRAPHICS: nVidia Quadro FX1800 768MB I also attached a photo of my Kernel Panic Thanks to anyone who will try to help Link to comment https://www.insanelymac.com/forum/topic/319194-dell-optiplex-380-macos-sierra-kp/ Share on other sites More sharing options...

alexander5230 Posted December 14, 2016 Author Share Posted December 14, 2016 Mhh.. isn't in plan to upgrade this cpu. It's Just a secondary build. So, you know what is the last OS X that I can install on this pc? (considering that I can upgrade RAM to 6GB) Link to comment https://www.insanelymac.com/forum/topic/319194-dell-optiplex-380-macos-sierra-kp/#findComment-2334041 Share on other sites More sharing options...
