Scilab 5.5.2 on macOS Sierra

Scilab 5.5.2 running on macOS Sierra

After the upgrade to macOS Sierra (10.12) Scilab 5.5.2 did not start and displayed the following error message:

This version on Scilab will probably fail on this system (10.12.5). Scilab requires 10.6.5 (Snow Leopard) or newer system.

Scilab 5.5.2 Error: This version on Scilab will probably fail on this system. Scilab requires 10.6.5 (Snow Leoprad) or newer system.

“Try anyway” did not succeed.

You need to copy the BLAS library to the app bundle. But you have to disable Gatekeeper first:

sudo spctl --master-disable

After type in the terminal:

sudo cp /System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/libBLAS.dylib /Applications/scilab-5.5.2.app/Contents/MacOS/lib/thirdparty

After start Scilab 5.5.2. The error appears again but clicking on “Try anyway” starts Scilab properly.

Scilab 6 does not have this problem!

To activate Gatekeeper again (if you really want it), type: sudo spctl --master-enable.
