Mikentosh2016 Posted October 5, 2016 Share Posted October 5, 2016 I've never seen that error message before? What is your process? Explain what you did to get to that window? How many drives do you have? Do you have a USB flash drive? How many partitions exist? Have you dual booted before? Do you know what MBR is?

bigben1 Posted October 8, 2016 Share Posted October 8, 2016 looks like you trying to install mac on ntfs partitioned hdd, you say you just installed windows 10 , if you only have 1 hdd its a long process ,in case you have another bootable hdd with os then boot into that and erase your windows 10 partition/hdd and make 2 partitions one formatted to ntfs for windows and another formatted to gpt ( mac os journaled) . install windows 10 to ntfs partition and then try to install mac os x on gpt partition. please post more details of what you plan to do.i am only guessing here.

yaximik Posted October 17, 2016 Share Posted October 17, 2016 Hi, I hit the same problem. Here is my config: Optiplex760, Core2 Duo E8400 @ 3 GHz, 16 GB RAM, 250 GB HD, ATI Radeon 256MB PCI Express DMS-59 Graphics Card. El Capitan 10.11 USB installer was created from El Pwn Version.dmg and Transmac (I have no Mac), works fine, boots into OS X. I reformatted onboard 250GB HD to 1 partition Mac OS Extended (journaled), but after language selection installation stalls with the same message: OS X cannot be installed on your computer OS X El Capitan is already installed on this MacQuit the Installer to restart your computer and try again Link to comment Share on other sites More sharing options...
