Build:
Motherboard: MSI Z97A Gaming 7
Processor: Intel Core i5-4670K
RAM: 16 GB 1600 MHz Corsair Vengeance
Graphics: ASUS Strix nVidia GeForce 970 GTX 4 GB
Upgrade Status: USING APFS It was a SUCCESS
Followed the steps as mentioned in Post #1 On Pre Existing El-Capitan Installation on a SSD.
Installation went without any issues.
Installing nVidia Graphics Drivers:
As soon as Machine was booted up after Re-Logging in to Apple Accounts, nVidia Downloaded and installed the drivers all by itself.
Once Installed, Machine restarted. BINGO! had perfect looking desktop screen.
Installing Audio:
opened Clover Configurator, Loaded the EFI Partition and Disabled SIP and Removed rootless=0 Boot Argument which was put on due to Toleda's Readme for Installing ALC1150 in El-Capitan.
Later Downloaded Latest Audio CloverALC master file from Toleda's Github Site and Run "Audio_cloverALC-XXX_vx.command"
Once Terminal Window showed "Process Complete" I simply restarted the machine and played my favourite track in iTunes...
Working Like a charm!
THANKS admins! You've made this upgrade a cakewalk!
