Verification on iMac: ignore steps 4--6 of obsolete installation README file!

After dragging to Applications folder in DMG manager and that pop-up window has announced copying completed, click on Sage icon.

A pop-up window announces "verifying", followed by message "Could not be opened because from untrusted developer": you MUST kill this via clicking on OK !

Go to Apple System Preferences, Security, General; unlock via superuser password, click on "Open anyway". Kill another (duplicate) pop-up.

"Jupyter" browser panel should open after verification is complete: click on Files, New, SageMath (etc) to open active edit window.

Default for program & output backup files is Documents folder.

A good deal of time wasted by both of us there, since that was what I had originally done. But the Jupyter page which opened is just as cryptic as everything else on site: at first I could not persuade it to actually do anything, so assumed the download had failed.

Current Jupyter online documentation found was just sufficiently out-of-date not to assist with getting it actually to start working. I have attempted to remedy the situation with my own expanded answer below.

The exact same error message was reported on April 22nd 2017 (unsigned): see

It appears that there remains some involvement of Python 2.7 in current Sage releases; and Sage may be defaulting to the Apple's Python 2.7.11 rather than whatever flavour it should be using. I don't see how to fix this ...

<< 10.12.3 dmg error message on a late 2012 iMac: >>

<< One step further on the iMac. After disabling the anti-virus software and removing anaconda from the path, the 10.12.3 dmg installs fine. >>

SageMath-9.1.app yields same error as SageMath-8.9.app, including identical step 5) headers:

| Sage Version 5.8, Release Date: 2013-03-15 | | Type "notebook()" for the browser-based notebook interface. |

| Type "help()" for help. |

The reference to python2.7 is suspicious: elsewhere in the documentation it is stated that Sage has been converted to python 3 ?

I'm relieved to hear from a human --- this query appeared at first to have immediately been cancelled by some brain-damaged robot ...
