The README.txt file you came across is outdated.
Once you have downloaded the xxx-app.dmg, open the dmg, copy the app to your /Applications folder, and open it, e.g. by double-clicking it.
You may have to visit the "Security and Privacy" tab of macOS's "System Preferences" to unquarantine the app. See
The app takes a very long time to start for some reason.
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Current Jupyter online documentation found was just sufficiently out-of-date not to assist with getting it actually to start working.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.
New SageMath macOS app:
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.

Welcome to Ask Sage! Thank you for your question!
Can you specify

sage-8.9-OSX_10.14.6-x86_64.app.dmg

I'm relieved to hear from a human --- this query appeared at first to have immediately been cancelled by some brain-damaged robot ...
Every post from a new user goes through moderation (to fight spam) but the website does not make that very clear or very friendly, sorry!
The reference to python2.7 is suspicious: elsewhere in the documentation it is stated that Sage has been converted to python 3 ?
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. |
