Thank you for reporting this. For me it is not clear what you mean by “Latest mac dev crashes on download of diff exts”. Brevity may be justified in the title but in the description please use full words/sentences to tell: what do you do, what is the expected outcome, and what is the observed outcome.

sorry, my bad. rushing. this is after deleting ~/.config/www.na-mic.org to have clean start (otherwise extension manager fails - see support item Ext manager and view controller broke) and downloading Slicer\_dev\_05-06-2017. after installing the diffusion extensions and restarting the above errors occur and the 2 modules fail to load. outcome should be all installed diffusion modules load without error.

@ihnorton I wanted to check these modules on Windows but DTIProcess was not available due to a build error. I’ve submitted a pull request to fix it: [https://github.com/NIRALUser/DTIProcessToolkit/pull/36](https://github.com/NIRALUser/DTIProcessToolkit/pull/36).

Thanks!! Hopefully the developers of that extension are on here as well to see this.
