Solved: camera matching profiles missing in Adobe Raw

The update for PS 19.1.5 and CR 10.4 came out a few days ago and at least on my Windows, the profiles are there for the a6300 (or at least the ILCE-6300 if that is the same), so that is the first suggestion, update to the latest version of PS/ACR.  Does the update not come out for Dutch users at the same time?

You might also just go check for the folder where Adobe installs the profiles and see if they are truly missing.  I am on Windows so cannot confirm directly, but from forum posts, I believe the place to look is under:

User Library>Application Support>Adobe>CameraRaw>CameraProfiles

with this note on a subsequent post from June 2017:

The Library folder is hidden by default in OS 10.6.

With Finder active, select the Go Menu, hold down Option key, and Library will appear, click to open the Library folder and follow Rodney's directions.

And for completeness here is where to look on Windows:
