I've updated my Ativ today to Sierra GM using the App Store, just wanted to share my experience.
First of all, i've been running El Cap for a few months now, thanks to this guide, so all credits go for duduclx and the folks who contributed there.
Still no Wacom drivers for Sierra, so no pressure sensitivity on the screen. If this is important for you don't update yet.
Haven't tried it yet, but the Wacom drivers for Sierra are published.
Ok, these are the steps I took:
1 - As usual, backup your ElCap install. I use Clonezilla.
2 - Download macOS Sierra GM from the Store.
3 - Update Clover to the last version. I did that by opening Clover Configurator, update it to the last version, and then select Install/Update Clover. It will download the last version, just check that you are installing it on your current OS X drive and that the same options as duduclx guide are marked.
4 - After Clover is update, mount your EFI partition and copy FakeSMC.kext, NullEthernet.kext, to /EFI/Clover/kexts/Other/ (You can delete all the others folders if you want)
5 - Download and copy HFSPlus.efi to /EFI/Clover/Drivers64UEFI
6 - Launch the Sierra installer. When the system reboots, select Boot OS X Install in Clover. The OS will start updating, and eventually it will reboot. In Clover, select Boot Mac OS X, and the final part of the update process will begin (VoodooPS2Controller.kext caused a kernel panic in this boot, i had to enter recovery and remove it from /Volumes/OSX/System/Library/Extensions/. I guess you can delete it from ElCap before launching the Sierra installer).
7 - After the update is done, you can configure your Apple id, etc. I had no sound, use EasyKext or whatever and reinstall AtivHDA.kext and the rest of the kexts in the Post installation section of duduclx guide. Reboot and you're done.
I mainly use the Ativ hooked up to a 23" FHD screen. Xcode, Logic X, the App Store, iCloud, are working as good as ever. Only flaws so far:
- No Wacom drivers yet.
- The mic isn't working so no Siri. Wasn't working for me in El Capitan either, never took the hassle to figure it out why.
- Physical volume keys on the side of the tablet are not working.
If anyone knows how to fix the last 2 issues would be much appreciated :-)
P.S. English is not my main language. Also, i'm no expert so maybe there are things that could have been done better or not needed to be done at all.
