I purchased a new Rpi 4 from Little Bird Electronics. It works fine except that Wolfram and Mathematica were not supplied on the 32 Gb Noobs card. I tried to download them but ran into problems. I contacted Wolfram Technical Support but they require a more recent release of Noobs 3.2.1 than I was supplied last week. I tried sudo apt-get update but that wont work. So I am stuck without getting a new edition of Noobs as below.
Thank you for your reply.
To check if Noobs contains Wolfram and Mathematica, I have formatted my sd card and re-install Raspbian (Full version).
I used Noobs version 3.2.1 (release date: 9/30/2019) downloaded from the link below:
Without additional installation processes, I can find them under home -> programming.
The version of Mathematica is 12.0.1.
Please let me know if you have any further questions.
