messed up file types after installing Jalview on a mac

I installed the latest 2.11.5.1 Jalview on my Apple Silicon macbook pro. It installed OK, but now my .pdb files show up as MIME type 'application/x-aportisdoc and several program refuse to download them. How do I reverse it?

Hi - that is peculiar. For the record, could you let us know which OSX version were you running, and did you just run the ‘install_jalview’ app in the DMG to do the installation ?

By default jalview tries not to touch .pdb or .*cif associations at all, since most folk working with structure aren’t interested in opening jalview directly for a molecule. It does register itself as an app that can handle these types, but definitely doesn’t set itself as the “preferred app” or adjust the MIME type bindings. Even more curious, application/x-aportisdoc is the old binding of .PDB files (PalmPilot Database).

You might be able to fix this by opening the ‘file information’ dialog (click on any .pdb file, press CMD-I) and selecting your preferred application in the ‘Open with’ section. You can see I have ChimeraX as my default app for pdb files..

A quick google suggests this isn’t a common problem at all - but I’ve seen the palmpilot database binding reported on some forums where someone uploaded a PDB file. To me that suggests if you are getting this MIME type for files downloaded from a website it might be the website or webapp has an old/misconfigured file/MIME type.

Sorry I can’t be more help - it is possible a simple reboot will fix this but do try to manually fix via the ‘open with’ option in the file info dialog first.
