The link to the release notes appears to be broken.
I just installed ifort 17.0.1 on Sierra using Xcode 8.2.1 - compiling a simple test code I get the following error
ifort -o test test.f90 -lm
ifort: error #10106: Fatal error in xcodebuild, terminated by IOT instruction
ld: can't open output file for writing: test, errno=21 for architecture x86_64
Thank you for the note. I corrected the RN link.
We do not support Xcode 8.2 in the current release. Support will be available in our next PSXE 2017 Update 2 coming later this month. You will need to down-version your Xcode to either 8.0 or 8.1 in the meantime.
