Obs v2.1 QuickLook Install

[fsantore]

Well it's good to know it's just me, I guess.  I did miss your complete crossed message #9, and so inspected the LaunchServices.framework as suggested.  On my main MacBook Pro M2 max machine, I see mostly your referenced nasa items, but also an out of place financial program reference.  The lsregister command may have had some changes in Sequoia, but I searched and found https://talk.tidbits.com/t/restoring-office-document-associations-after-sequoia-upgrade/29088, which led to some excellent Electric Light discussion of the problem at https://eclecticlight.co/2019/03/25/lsregister-a-valuable-undocumented-command-for-launchservices/ .  Running one of the suggested lsregister rebuild commands did indeed seem to fix the .fit quicklook issue, but had side effects on the OS.  Rebooting resolved the side effects, but restored the problem.  Do you have a suggested complete lsregister rebuild syntax I might try?

Although lsregister on Sequoia has a slightly different size than the one on Sonoma, its reported arguments (see with -h argument) are the same, so I assume it also works the same. Search on this forum for "lsregister" to see how to use it. Your second link also describes it well.

Also check /Library/QuickLook/ and ~/Library/QuickLook/ to see if you have any manually installed FITS related Quick Look generators on your system, which are obsolete on Sequoia but might mess up things for you.

Thanks, your lsregister search idea allowed me to review our prior discussion.  But neither suggestion led to a working .FIT functionality.  I see now that .FIT and .FITS are the same, existing only because Windows supports just 3 letter extensions.  It is curious however that I did try a sixth mac here, with the same deficiency.  I'm relegated to 'Forklift'ing bulk file renames when transferring acquired images to my post-processing system, which while not the worst situation it is an additional step (I'll probably often forget), and one new step that seems to be just for me.

I also see that my acquisition SW has options to set the extension.  They were all FIT, so are all now changed to FITS.  I should be good going forward in spite of the puzzling behavior. Also, Forklift is a very capable MacOS utility that covers many functions related to bulk file manipulation.  Renaming my existing image library files from FIT to FITS was easily accomplished.
