There was a problem with Sage and MacOS El Capitan which was solved here: For quite a while I used beta 1 of 6.10 which worked fine. Today I decided to move to 6.10 and it's back to non-working. What's going on?

✗ sage

│ Type "notebook()" for the browser-based notebook interface.        │

How did you manage to get there? You should

  • Open the DMG (or tar.bz2)
  • Drag the SageMath folder / app to where you want it to be (possibly rename it)
  • Start sage

This will then automatically patch paths in binaries. Once it is installed you cannot move the installation any more.

I did exactly this in the correct order. On the first start it also patched a lot of binaries (lots of stuff scrolling) and then yielded this error. Let me try again.

OK, reproducably, If I rename the folder from SageMath to just "sage" I get this error.

Just to be clear, you can only move / rename the SageMath folder before you start it for the first time. Once you started sage, you can neither move nor rename it. The "Updating various hardcoded paths" message is incorrect and does not do it.

OK, thanks. It works now. So the directory is not relocatable after first start?

Correct, thats how it works
