Hi diegovb, have you run the 3DMark for the 1070? I already got a eGPU of 970 and now planning to upgrade to 1070 or 1080. But I am not sure the tb2 interface is enough for the new GPU. So if you can run a 3DMark test it will be very helpful, thanks.

@dark330 I met the same problem after I install the Optimus on the 2015 13' MBP. When I hold the alt to the boot menu, there are only EFI and OSX, the windows is disappeared. And when I try to restore my EFI backup, some error occurs and the backup file is gone.

@tranj10 I have read your guide, now I can boot into OSX with the egup 100%, but I cannot boot into windows 8.1. I think the EFI modification is not working with the new 2015 13' model and want to restore the EFI. Is there any way that I can do this without the backup file and the factory reset?

@dark330: If you look in page 8 of this thread, someone has reported issues with installing Optimus on the 2015 13" MBP. I wrote an implementation guide for this model at http://forum.techinferno.com/implementation-guides-apple/10614-2015-13-macbook-pro-gtx970%4016gbps-tb2-akitio-thunder2-win8-1-osx10-10-%5Btranj10%5D.html. I do not use the Optimus boot file modifications at all. Take a look at my power up process in the guide. It gives me a very good success rate (~90% from my experience).

To get rid of Optimus boot modifications on your MacBook you can try to restore your EFI backup or reset your MacBook to factory settings after disabling FileVault from OS X.

Great script, tested on my 2015 13' RMBP with GTX970.

hi, can anyone share an EFIBackup.dmg? Mine is disappeared when I try to restore the default mode. Thanks.
