rJava and tabulizer not working on mac Catalina

I have tried everything to try and get rJava to load but I have failed. Any suggestions as to how I can solve this problem? When I run library(rJava) in R (not R studio) it seems to load.

rgl install failure in Rstudio on mac

rgl installed
Error : .onLoad failed in loadNamespace() for 'rgl', details:

Warning message:

rgl
You don't really post a question (hence the negative scores others have given you), but it appears that the error message is telling you that rgl is failing to load because libGLU.1.dylib is not found.
You can probably fix this by installing XQuartz, since it looks like you're on a Mac. Go to https://www.xquartz.org to get it.

Loading 'rgl' package gives the same error message.
How can I solve this?

This might be useful for those having the same issue on Linux (long discussion, skip to the end to get the final solution):
http://r.789695.n4.nabble.com/Where-is-the-tcltk-package-td3434915.html
If your version of R > 3.0 then Tck/Tk 8.6.0 come bundles with it. You should be ok deleting it
