I just downloaded Sage 4.5.3-OSX10.4-intel-i386-Darwin and set out to
install it on:
Hardware: MacBook Pro 5.1, Core2 Duo, 2.4 GHz, 4 GB.
Software: OS X 10.6.4 64-bit
Following instructions in the file sage-README-osx.txt , items 1), 2),
and 3)
proceed faultlessly.
But Item 4) is gobbledegook:
4) Select to run it with "Terminal":
Choose Applications, then select "All Applications" in the
"Enable:" drop down. Change the "Applications" drop down
to "Utilities". On the left, scroll and select "Terminal".
-----------------------------------------------------------------------
I have a directory named ‘Applications’, which includes both a directory
'#Crunch’,
which includes Sage, and a directory ‘Utilities’ which includes
‘Terminal’.
I can either drag Sage over to Terminal, or open Terminal and indulge in
appropriate but undisclosed mumbo-jumbo.
‘All Applications’ and ‘Enable’ are not options in my world.
-------------------------------------------------------------------------
So I open the Sage folder and drag the sage application--marked by a Unix
icon--over to the Terminal icon in another Finder window. Terminal opens,
and then in polychrome text tells me:

This looks as though it needed permission repair of .sage. I went looking
for .sage , and discovered that the sage folder contains some 20,000 files.
Spotlight and EasyFind fail to locate a .sage item. The last time I did a
blanket chmod on anything approaching the size of sage, allowing read/write
privileges to everything therein, my MacBook had to spent a week in the next
county in the hands of the local Mac guru, so I am reluctant to try this
again.
Searching for DOT_SAGE opens a webpage in Safari, my default browser, and
turns out to be part of Sage Reference 4.5.3, sort of an html version of man
pages (?), but in any case, not something that I seem to be able to or want
to change permissions on.
For better or worse, I resolutely avoided Unix, FORTRAN, C, and
TRSDOS/MSDOS/Windows at all possible opportunities, beginning in 1960, 1963,
1972, and 1978 respectively, doing all serious number crunching in Forth
(world CO2 models, Mie equations, population biology, whatever) when I
could, so I approach Sage and Terminal with trepidation and
unfamiliarity--but impressed by the sheer inclusivity of Sage!
Can you tell from the above messages what isn't going right?
