Hey guys, This is a tutorial on how to fix (or at least try to fix) the second stage boot, when you're having these issues: missing logo and loading bar being displayed on the bottom left corner of the screen. Might or might not work for other issues. So proceed with caution. This is an issue that I experienced starting with early stages of development in Yosemite. Still continued in El Capitan. So this thread is primarily for these two versions of Mac OS X. Not sure it will work on earlier versions, cause I never tried it.

The current Nvidia beta drivers require macOS 10.11 El Capitan or 10.12 Sierra,. The drivers should function on the Mac Pro 3,1; 4,1; and 5,1 from 2008, 2009. However, you might not get boot screen support, correct?

So far it worked in Yosemite, El Capitan and Sierra. Please, note that I did not test this on all video cards. So it might or might not work, depending on that. Don't take this as a final solution for everything.

Also, I'm pretty sure this won't work with iGPUs. So I would strongly suggest to look around for solutions if that's your case. This tutorial is not for multiple display setups! Please, don't use it for that! Especially not in iGPU + dedicated GPU combos. Known issue: if you're using the auto-login feature, try to disable it and use the regular login screen.

Otherwise you won't get the second stage boot (confirmed as fixed in Sierra). This tutorial would have not been possible without the help and insight of: Pike R. Alpha cecekpawon Mirone Riley Freeman So all the credit goes to them.

Office 365 for mac trial. I just put this together based on my successes and failures. Succesfully tested with: NVidia cards: • GeForce 210 • GT 640 • GTX 650 • GTX 660 • GTX 670 Superclocked+ 4GB - works partially (ok for 1080p, with CSM disabled, but no second stage in higher resolutions) • GTX 750 Ti - works partially (ok for 1080p, but no Apple logo for second stage in higher resolutions) • GTX 760 • GTX 780 • GTX 960 • GTX 970 - works partially (ok for 1080p, and with CSM disabled, but no second stage in higher resolutions) ATI cards: • Might work on other graphic cards, as well.

But these are the ones that worked so far. Please, share if you got good results with another video card. Also, the same thing can be achieved by modding your DSDT. Unfortunately this thread does not make the object of that method, nor am I able to help you with that, since I really have no idea how to mod a DSDT, so far. Also, to be honest, this method seems a bit easier. Nonetheless, try this at your own risk! I'm not responsible for any damage that you might cause to your computer/components etc.

Also, please, note that this tutorial is not perfect. I'm doing my best to make it as easy to understand as possible. Also, I'm opened to suggestions and I'm doing my best to improve this in the future. Still, it's not perfect. So keep that in mind.

• Check the box next to any Mizage apps (Divvy, ShortStop, etc). Universal access on mac for csgo. • Click the lock icon to make changes.

Suggestions are appreciated though. Please, note that, if you've got a video card with GOP UEFI Bios, you most likely don't need this tutorial in the first place. All you need is to disable CSM in BIOS (motherboard dependent). Note that, by doing this, only GPT drives will be loaded. So if you've got Windows installed on another drive, for example, you won't be able to select it anymore, if it's installed in 'legacy' mode.
