set boot volume to another HDD and activate/deactivate NVIDIA-Driver

Scripting Forums AppleScript | Mac OS X
#1

Hi,
sorry for my bad english, in german it would be easier for me :wink:
I have a Mac Pro with 2 SSD (One with Yosemite - Volumename: “SSD 500”, one with Mavericks - Volumename “SSDEVO”). I need a Applescript to change the Boot/startup-Volume from one SSD to the other and to deactivate or activate the NVIDIA-Driver. i am a total noob and stuck at this point, when I’m in Yosemite und want to reboot to Mavericks with NVIDIA-Driver turned off:

do shell script “bless --mount /Volumes/SSDEVO/ --setBoot --legacy” password “xxxxxxxx” with administrator privileges
do shell script "sudo nvram boot-args=“nv_disable=1"” password “xxxxxx” with administrator privileges
tell application “System Events” to shut down

I know there is a problem with the path (/Volumes/SSDEVO/) and the double " in the second line. Can someone please help me with this?

Found the solution:

do shell script “sudo systemsetup -setstartupdisk /Volumes/Name_of_the_SSD” password “xxxxxxx” with administrator privileges
do shell script “sudo nvram boot-args="nv_disable=1"” password “xxxxxxx” with administrator privileges
tell application “System Events” to restart
