installation issues with sage 7.6

[Alex Jordan]

I'm installing Sage for the first time, on a Mac OS El Capitan. I downloaded from:
http://files.sagemath.org/osx/intel/index.html

the file sage-7.6-OSX_10.12.3-x86_64.app.dmg, and dragged Sage into Applications.

The first time I opened Sage, a window opened that asked if I wanted to update something. I didn't take careful note of what it asked. I consented, and then two terminals opened and for a minute or two a log of some sort scrolled past.

Now when I open Sage, a terminal opens with the following output, including what appear to be error messages. Then nothing happens, even if I wait a long time.

Is this evidence something is wrong with my installation? What should I expect to see to actually start using Sage? I was expecting some kind of Sage input tool.

El Capitan is OS 10.12, it might not run software for 10.11.
Your best bet might be to build from source-unless there is already a 10.11 binary install.

I installed Sage 7.4 and it's running well. For me, for now, this is an acceptable situation. Are there release notes for 7.5 and 7.6 that I could review to see what I am missing? The release notes here only go up to 7.3.

[Dima Pasechnik]

you are missing OSX 10.12.

Ah, thanks. I misunderstood your first message. So I will need Sierra if I wish to run 7.6.

Well, an alternative is to compile Sage yourself, or wait for some kind soul with OSX 10.11 to build and post a binary installer.
