I have successfully been using the Matlab 2017b with package toolbox in macOS Sierra. I just upgraded to macOS High Sierra and now when I run the following:

>> i2c = i2c('aardvark',0,0);
>> fopen(i2c);
Error using i2c/fopen (line 82)
Unsuccessful open: Cannot connect to the device. Possible reasons are the device is in use or not available. Use
INSTRFIND to determine if any instances of open connections to the requested device exist in this instance of
MATLAB.
>> instrfind
     I2C Object : I2C-0-34h
     Communication Settings 
        BoardIndex          0
        BoardSerial         0
        BitRate:            100 kHz
        RemoteAddress:      34h
        Vendor:             Aardvark
     Communication State 
        Status:             closed
        RecordStatus:       off
     Read/Write State  
        TransferStatus:     idle

So the Aardvark adapter is found, but Matlab cannot seem to communicate with it.

I see that I have a symbolic link in /usr/lib/aardvark.so to ~/Documents/MATLAB/SupportPackages/R2017b/toolbox/instrument/supportpackages/aardvark/driver/maci64/aardvark.so

How do I get this to work again?
