    Ok guys,

    Where to start I purchased a mac pro 3,1 2008 model about 2 years ago and was running OS X Sierra flawlessly and then i had an issue with the HDD so i put in a new 1TB SSD drive i installed windows as my main operating system and didn't bother about OS X as i was wanting to play all the Battlefield games and Mac did not support these games, i originally had a Sapphire 7950 3gb Mac edition card running in the machine but ended up selling that and putting in a RX560 Gigabyte GPU 4GB so games would run better, my issue is that i am now wanting to install OS X High Sierra with Dosdude1 Patch but i cant as when i turn on my mac pro i dont get the apple boot logo and the screen stays black till windows is loaded.

    My question to you guys is "is there" a work around so i can install OS X High Sierra on my machine and have that as my main operating system or am i stuck with windows all together and i will need to buy a graphics card that is apple configured and it will give me a boot screen???

    Specs of Machine are as followed

    Mac Pro 2008

    2x Xeon 2.8ghz Processors
    32GB Ram
    Gigabyte RX560 4GB GPU
    Windows 7
    2x 320GB HDD 1x 1TB SSD

    Any help would be greatly appreciated and i thank you all for your time

    The NVMe patch was originally discovered to work on Sierra.

    Do you have another Mac (or access to one)? You can connect your SSD to that Mac via a USB adapter, install MacOS on it and then move the SSD to your Mac Pro.

    But really, life without boot screens on a cMP is annoying at best. You really should consider picking up an EFI-capable card to have on hand. Even an old GT120 or something.
