Run the post-install a second time. Sometimes that's necessary for it to work.
Got a tip for us?

Tried it. No dice. It's also done in like 10 seconds
[doublepost=1468000287][/doublepost]Is it because I upgraded and didn't do a clean install?
Yeah, it may be because you did an upgrade. Let me see if I can figure out a way to ensure the kextcache is rebuilt.
I suppose I'll have to dig out the 09 MacBook. Or is there a terminal command I can try?
Ah, I figured it out. I'm updating the post-install patch now.
I'm sure this has been answered, but for those of us who are currently running Beta 1 on unsupported macs do we just run the public beta installer from within the Applications folder..? Or is it necessary to make the installer USB again?
Also, as I understand it we should not use Disk Utility to format the disk beforehand, but instead should just run the installer and select the Mac drive...is this correct?
Ok I will remake the USB - I am assuming using the patcher just the same as before. I am currently running a Bootcamp setup (everything is backed up). ..I would however like to keep my setup if possible. If I upgrade using the installer (without formatting the disk) and then use Gdisk to rebuild my hybrid MBR should it work?
I'm still curious how my situation fits into all this. I pulled my drive from my MBP, updated to developer beta 2 using my supported MAC then put it back. I have done nothing else so it feels like I have missed a step but all works as far as I can tell.
Ok I'll let you know. I'm gonna try to do the rebuild caches terminal command. My MacBook is stupid slow
Just type "rm /Volumes/<target volume>/System/Library/prelinkedkernels/prelinkedkernel" in Terminal.
Thanks Dosdude!
Does this mean that I run the installer from the Applications folder, avoiding having to remake a new USB?
Do you have a link to the most current patcher?
Can you just clarify what you meant by upgrade-install? Is there an option to install by running the beta installer directly from Applications...or is the only possible way to remake a new USB by following your old instructions from beta 1?

I meant just installing Sierra on a volume that contains an install already, without erasing it. That way, all files and settings will remain in tact. You still have to create a patched USB and boot from it, but just skip erasing the disk with Disk Utility.
Well I have to sell my 27" iMac because it's 3 months older than the minimum age for unlock with Apple Watch. /sarcasm
I did an upgrade to PB using yesterday's (2.5?) patcher. Looks like it's running fine. Seems like you made a bug fix to purge kext caches for my upgrade (from DP1) scenario. Should I remake and post install? Any reason to worry?
Got it, thank you. To your knowledge should this keep the ability to rebuild my Bootcamp intact?
To explain, what I have always done on El Capitan and now with Sierra is to install the way that you are describing (no formatting in Disk Utility) in existing setups where I had Bootcamp (I always use Bootcamp).
What I found is that of course the partition stays intact, but that trying to boot into the parititon results in an operating system not found error message. This is easily fixed using a utility called Gdisk to rebuild the hybrid MBR.
In my testing I have found that Bootcamp can always be salvaged this way so long as the partition size is not altered (then it breaks).
So, do you have any insight on this? I am going to do the following, please let me know if this is correct:
1. Rebuild the USB installer with the public beta using your utility
2. My current Sierra install is on my partition named "Macintosh" - I am going to chose to install the new beta on Macintosh, without reformatting it first in Disk Utility
3. Following install it will most likely not boot up giving me a "no smoking" sign - I will reboot to the USB and run the post-installation patch
4. Hope for the best
Am I missing any steps? Thank you
