Hey Tex, thanks for the quick reply. Below is what I sent Apple and even had them on the phone last night and they suggested I take it to an authorized Apple dealer to see what they could figure out. So today I did and we tried a couple other times in safe mode but still no go. They suggested to go into recovery mode and try to change in the terminal but a little leery of that. Anyway you mentioned about using a non-apple cd drive, my wife’s Samsung works with no problems. I just want my apple cd to work and don’t understand why an apple device wouldn’t do the same???
I have an early 2011 MAcBook Pro running 10.12.2 that I just replaced the non working internal Optical drive with a new second SSD that greatly increased the speed of the mac. I then bought an external usb apple superdrive but when I connect to my computer I get “The Apple USB SuperDrive is not supported on this Mac”. My wife’s Samsung works fine on here, not sure why an Apple product doesn’t do the same? But obviously it is a common problem form what I’ve discovered trying to find a fix. I have tried the terminal window codes in the two methods I found but in both cases get an error that will not save. First try was to type (sudo nvram boot-args=“mbasd=1”) in terminal then password and when I hit enter I get (nvram: Error setting variable - ‘boot-args’: (iokit/common) general error).
Second try was as follows...
1. open a terminal, 2. type (on a single line) sudo pico /Library/Preferences/SystemConfiguration/com.apple.Boot.plist 3. Insert mbasd=1 in the String 4. Save (press Ctrl-X, answer yes to save by pressing Y, press enter to confirm the file name). 5. Restart your machine. However when I hit enter to confirm the file name I get this error...
[ Error writing/Library/Preferences/SystemConfiguration/com.apple.Boot.plist.
Apparently these methods have worked for several others but not sure what I’m doing wrong.
Have a Merry Christmas Tex for you and your family.
