Anyone figure out a fix so .PEF thumbnails (from K1) show up in MacOS finder?

I would like to keep the files recording in .PEF because I like the way lightroom processes the Pixel Shift from PEF vs DNG... however I cannot see the thumbnails in Finder on Mac. I can only see thumbnails if recorded in DNG.

Any help is appreciated...

Until Apple updates Digital Camera RAW Compatibility to include the K-1 there will be no thumbnails. Even after they do so there won't be small thumbnails in the Finder, only in Open dialogs.

I had the same problem. After trying out everything here and nothing resolving this issue, I solved with this solution.
go to your user preferences folder at

/users/(your user name here)/Library/Preferences

and move this files to desktop (to keep a backup just in case)

Reboot and login

Everything should be ok now and you can delete the file above
some of your preferences may change but its easyer to redefine them than to click all icons to find the Photo you want.

I think I solved it...
if your "open with" prefereence is not "preview" like for example it's PSE and the program you have selected does not support pef then no icons will be generated.
you have to set "Preview" as the default "open with" program.

To whom it may concern, just downloaded the El Capitan RAW update for my Mac, and the K-1 profile was included.
