Bug with MRview on MacOS Sonoma

Dear MRtrix experts,

I updated my machine from MacOS Ventura with Intel silicon to a more recent MacOS Sonoma 14.1.1 with Apple Silicon.
Following this, when opening MRview I get the following error in the Terminal:
“mrview[775:8954] WARNING: Secure coding is not enabled for restorable state! Enable secure coding by implementing NSApplicationDelegate.applicationSupportsSecureRestorableState: and returning YES.”
MRview opens but when I load a Tractography file (that I was able to open without issues with the previous OS), it continues loading, being impossible to be used.

Could you kindly help me?

Appreciated your support,


The two issues are unrelated.

Issue #1:

This is the consequence of moving from Intel to Apple Silicon. For the time being you will have to use this workaround:

Issue #2:

This is the consequence from updating to Sonoma as also reported in shview: Secure coding is not enabled for restorable state! on macOS 14 · Issue #2740 · MRtrix3/mrtrix3 · GitHub. Interestingly, you get the warning also for mrview, while for me it only shows up when running shview. It is just a warning, so mrview should operate just fine. I suspect this will get fixed in the next update.

Dear bjeurissen, thanks for your help, I will modify the config as suggested!
