Thank you very much Alberto,

I tried:

brew tap osgeo/osgeo4mac
brew unlink gdal
brew unlink proj

brew install osgeo-gdal
brew install osgeo-proj
brew link osgeo-gdal
brew link osgeo-proj

install.packages("rgdal", type = "source")

Error: package or namespace load failed for ‘rgdal’ in dyn.load(file,
DLLpath = DLLpath, ...):
 unable to load shared object

6): Symbol not found: ___addtf3
  Referenced from: /usr/local/opt/gcc/lib/gcc/9/libquadmath.0.dylib
  Expected in: /usr/lib/libSystem.B.dylib
 in /usr/local/opt/gcc/lib/gcc/9/libquadmath.0.dylib
Error: loading failed
Execution halted

After trying to find a solution, some people suggested me to wait for the
binary packages.
