It could be a proxy issue and maybe you need to manually install. Discussion below should help.

> I just downloaded 4.8.1 on my MacBook to test out the program for our work with DTI and tractography, and when I open the extension manager, it fails to load any of the extensions. It stops around 66% every time. I’ve tried shutting down the program and opening it back up, uninstalling and reinstalling, etc. I even downloaded the nightly build to see if it would work, and while it said it had loaded to 100%, no extensions would show up. Any suggestions?
