Just installed Public Beta 3 and refind behaviour is back to its usual awesome self. A refind-install undid the boot coup as usual and now the mac reliably boots refind from the internal EFI partition as its supposed to. Looks like it was a bug with Public Beta 2 which is now fixed -- that's what we get for running betas! Thanks for your responsiveness and your great piece of software that the mac eGPU community in particular really depends on!

Indeed. I think the issue here is that, in addition to a boot coup as usual with a major OSX update, this particular version of OSX either disregards the boot order or resets it upon booting or something similar. Refind-install has no effect. Bless only works if followed by a reboot command, and stops working once OSX boots once, etc. Consensus seems to be that it's a bug in this beta release of OSX. Looks like a new one is out today -- will try and see if it's fixed and let you know.

Hi Folks: TL;DR: I found a workaround for this bug: Download the refind-flashdrive package. Make a bootable usb drive by following the refind-flashdrive instructions. Bless the USB drive (your device may differ): bless --device /dev/disk2s1 --setBoot --verbose Reboot via command line: sudo reboot Don't hold down OPTION at boot time, just let it reboot. The computer should then boot from the thumb drive, which in my case discovered my existing refind config and I was good to go. Confirmed eGPU working...
