Thanks for trying the Beta.
Although the 2017 Beta Intel Python does not officially support OS X El Capitan, we were at least able to install and run Intel Python on that system. Are you trying to install python 2 or 3?
Have you installed the gettext library required by Intel Python3.5? You can find more information in the Known Issues document:
I've installed gettext through brew and the same error remains: "intelpython35-2017.0.007.app" is damaged and can't be opened. You should move it to the Trash.
It appears to be an issue with GateKeeper. Please run the following command in a terminal and try the installation again:
xattr -rc /path/to/<intelpython>.app
Let me know if this works for you.
Hi Chris, Paul
xattr does fix the launch of the installer. Thank you.
If gettext is installed with brew, it's by default keg-only so you have to run "brew link --force gettext" to make symlinks in /usr/local to make the installer find it.
