While cleaning up my Mac I found the following folder:
Macintosh HD->Library->Application Support->MICA
The folder contains a Plugins folder which contains Materials.bundle
Anyone know what this is? Can I ditch it or is it a part of the OS?
MacBook Pro 13", macOS 10.14
why do some posters feel the need to be so hostile when answering?
the question was

a good answer was
MICA is part of Apples CoreAnimation
Some of us who have been migrating our Mac's since the 90's invariably have a bunch of crud in the system folders that No Longer have any buisness being there and the OS has not removed over time, hence why we are having a look and wanting to remove stuff. just today i've removed a bunch of extensions from 2005.
these from 2013 & 2015 don't look like they need be their either
the BJUSB is canon bubblejet technology. No idea what CalDigitHDProDrv.kext is or if its still needed as its 7 years old.
This is one reason Apple has moved to a read only Volume in the macOS as we move forward in Catalina.
Your days of " cleaning up Macs" in the system library are limited; or simply do not upgrade beyond your Mojave.
Thats great so long as all the old unnecessary crud from the last decade plus is also excluded too.

Typically you have no business in the System Library — it is a good way to bork your macOS.
There are 3 Libraries the one you have free rein over is the user Library. the path is ~/Library
From your Finder >Go> Go to Folder>Library (if you do not see it hold the option key)

Thank you for the warning. I'm very comfortable in the system library, been cleaning up Macs since the early 90's. This is the first time I noticed this folder. Noticed that it was signed, but that can easily, sort of, faked so I figured I'd check. Thank you for explaining the purpose of this folder.

About the read-only system volume in macOS Catalina - Apple .
It's code-signed by Apple, so probably best left where is 😲
$ codesign -dv --verbose=4 /Library/Application\ Support/Mica/PlugIns/Materials.bundle
Executable=/Library/Application Support/Mica/PlugIns/Materials.bundle/Contents/MacOS/Materials
Identifier=com.apple.Materials
...
Authority=Software Signing
Authority=Apple Code Signing Certification Authority
Authority=Apple Root CA
...
I have this same question.
it would really help if there was some explanation as to what this "Materials.bundle" is for and who made it. Signed by apple means nothing. Doesn't mean its not interfering.
I did remove it the other day, then i did an inplace os reinstall and its back so suggests apple installer is putting it back.

Not 100% sure what CalDigitHDProDrv.kext is for, might be part of the RAID support. It is an OSX system file though, not a third party driver. I would keep it.
MICA folder
