macOS Quick Look Extension for .mif files

Promotions

Dear MRtrix community,

I would like to promote a small macOS utility I have just released, a novel Quick Look Extension for .mif and other medical image research formats that works on modern macOS.

Inspired by the old and deprecated DTI-TK Quick Look plugin by Gary Hui Zhang, which brought similar functionality to older versions of macOS but is incompatible with the Quick Look extension architecture of current macOS versions

To address this, I built MIQ, a free and open-source, modern macOS Quick Look extension. Simply hit the Spacebar in Finder to instantly see an orthogonal slice view along with a metadata panel. No app switching, no waiting.

:white_check_mark: MRtrix (.mif, .mif.gz)
:white_check_mark: NIfTI-1 & NIfTI-2 (.nii, .nii.gz)
:white_check_mark: FreeSurfer (.mgh, .mgz)
:white_check_mark: Works on Apple Silicon & Intel
:white_check_mark: Compatible with macOS 15 Sequoia & 26 Tahoe

I’d love for you to try it and share any feedback! The app is notarized by Apple, you can just download and install it. No need to circumvent any macOS security measured or to compile on your own.

Major updates with MIQ version 1.0.0!

  • The preview is now fully interactive (scroll, drag, window/level). You can quickly explore your data directly in Quick Look, even in 4D (multi-volume). Especially convenient for DWI data.
  • The view is configurable from the main app. For example, choose to display images “as stored” or reoriented.
  • Support for the NRRD format has been added.
  • Thumbnail extension: display an image slice as a file icon in Finder (optional, activate from the main app).
  • Built-in updater.

Download from GitHub or install via Homebrew:
