Here's a little more detail on what happened. I was trying to git pull ci_hsc and rerun lsstsw. On lsstsw, it was asking me for a username pyfits: ok (0.3 sec). python_d2to1: ok (0.4 sec). stsci_distutils: ok (0.3 sec). geom: ok (0.3 sec). testdata_deblender: Username for 'https://s3.amazonaws.com': So on lsstsw, I git pulled, reran bin/deploy. Still was prompted for a username. Then I swapped the git-lfs that was in my lsstsw (lsstsw/lfs/bin): Yusras-MBP:bin yusra$ ./git-lfs-old version git-lfs/1.5.5 (GitHub; darwin amd64; go 1.7.4; git c2dcd6f5) out for the one I just upgraded via homebrew: Yusras-MBP:bin yusra$ ./git-lfs version git-lfs/2.4.0 (GitHub; darwin amd64; go 1.10) And now it doesn't prompt me for a username and I am happy. As for ci_hsc, here's the log: 20180413T130744.219132507.log

Jonathan Sick added a comment - 24/Apr/18 3:07 PM We've decided to state git-lfs version 2.3.4 or later, since 2.3.4 is what's deployed by lsstsw: https://github.com/lsst/lsstsw/blob/master/bin/deploy#L17 I think we're still not entirely clear why this change came about since our own Git LFS server infrastructure didn't change. It may also be a Mac-specific issue.
