But Sage keep saying
Error: Neither ImageMagick nor ffmpeg appears to be installed.
And indeed
from sage.misc.sage_ostools import have_program
have_program('convert')
returns false.
But I do have ImageMagick installed by homwbrew.
i.e. it works perfectly in Terminal.
What Could Possibly Go Wrong?
(macOS 10.13; Sage 8.3; Imagemagick 7.0.8.)Symbol 1Tue, 11 Sep 2018 19:18:14 -0500http://ask.sagemath.org/question/43643/Problems installing Sage 8.3 on OSXhttp://ask.sagemath.org/question/43594/problems-installing-sage-83-on-osx/ I am trying to install Sage 8.3 on OSX (latest version, 10.13.6)
I usually download the disk image and drag to Applications, so I attempted this with the file
> sage-8.3-OSX_10.13.6-x86_64.dmg
and checked that the MD5 checksum matched the advertised MD5 sum on the download page.
On opening the disk image, a dialog saying "Verifying" opens up, and starts to verify, but then halts with an error message that I have not seen before:
"The following disk images couldn't be opened, (name of file), image data corrupted"
I downloaded again, and once again the MD5 checksum (called from a terminal window) was correct.
Then I ran Apple's "Disk Utility" and attempt to verify the image, which failed and produced a bunch of diagnostic data that I do not understand. (I have attached this diagnostic output in case it may be helpful)
Any assistance gratefully received.
Diagnostic output from "Disk Utility" starts here:

For the command line version, I've set my path variables correctly and Maple easily runs from Sage. However, when I open the GUI version of sage, Maple isn't on the path and I'm not sure how to add it (even temporarily).
Following up to the answer below, my issue might not be that the PATH is in error. I've set the path correctly (or so I believe), but Maple still isn't accessible from the GUI version of Maple.Michael BurrFri, 27 Jul 2018 20:24:51 -0500http://ask.sagemath.org/question/43183/How To Accept Remote Network Connectionhttp://ask.sagemath.org/question/39456/how-to-accept-remote-network-connection/Hi, I use Mac OS's native Sage App. I can access Sage's Jupyter notebook from that Mac using localhost:8888. I researched a bit and find out if another computer needs to browse the same Jupyter notebook, one needs to start juypter by passing --ip '*' (otherwise it only accepts localhost traffic and will give a Connection Refused error).
But since I am clicking a Mac OS Sage icon to start the server... I am not sure how I can specify the command line option. Please give me some hints.
Thanks

I am using Sage on my mac terminal. The mac keyboard does not have home or end key. I check out several combinations and they does not work in Sage terminal platform, but works on Rstudio. How do I recover the home and end key?
Thanks.Dianbin BaoFri, 10 Nov 2017 14:43:35 -0600http://ask.sagemath.org/question/39489/Jupiter and notebook start problemhttp://ask.sagemath.org/question/38844/jupiter-and-notebook-start-problem/ I am running MacOSX 10.11.6.
