I installed seadas 8.3.10 for MacOS Ventura 13.5, however when I try to install ocssw processors, it is giving error.
execution exception: install_ocssw failed with exit code 127.
Check log for more details.
env: python3: No such file or directory

You need Python (3.6 or later) and Python requests package (v2.18.0 or later) for install_ocssw to work. See

If you plan to run OCSSW on command line, you also need to add two lines to your .bashrc
See Command Line Configuration at the bottom of the download page

Does your Mac have Intel chip or Apple chip?

Is this Mac the same Mac as in this post? -- viewtopic.php?p=16235#p16221
