Can't find installed color profile Lightroom Classic (mac)

[Steve NB]

I'm running 14.0.1 Lightroom Classic on my macbook pro.  I would like to see how my images in lightroom are going to look when printed.  I downloaded the ICC profile for the type of print I was doing and installed it in the "MacIntosh HD/Library/ColorSync/Profiles" folder and in my accounts Library/ColorSync/Profiles (just to be safe).  When in the developement mode checking "Soft Proofing" and selecting "other" under profile I get a box with no profiles.  I quit LR and restarted and still no profile.  Any ideas?

I'm really not that concerned about color as I am the luminosity of the final print.  I know the dynamic range of a print is not going to be as large as my display device and I need to see what the final print would look like.

This is my first attempt at trying at using print color management.  My previous prints I had to make several test prints making adjustments to get the desired luminance range.  When soft proofing will the changes needed to make the print look "right" be saved under soft proofing or are the changes going to also end up with what I also see when I turn off soft proofing?

What type of printer or press conditions does the profile represent? Do you know if the profile is based on RGB, CMYK, or grayscale?

The reason I ask is that unlike Photoshop and Camera Raw, Lightroom Classic works only with RGB-based print profiles, such as the profiles that photo inkjet printers use. It won’t list non-RGB profiles.

Yes that is it.  It's a CYMK profile.  I didn't notice the foot note indicating it wouldn't work for LR.  I guess I'll have to deal with it in PS.  Thanks
