I think a lot of us Mac useRs install the KyngChaos super-package (GDAL, GEOS, PROJ, SQLite and UnixImageIO framework described and linked to at:

https://www.kyngchaos.com/software/frameworks

I see that another version was released earlier this year which I had not installed, so I only had GDAL 2.1. I got this when loading `rgdal` version 1.3-1 (and I see that I'm a couple of minor versions behind. so I'll update) I did wonder that the message about linking to `sp` ver 1.2-7 didn't match my current version of `sp` which is 1.3-1

library(rgdal)
Loading required package: sp
rgdal: version: 1.3-1, (SVN revision 747)
 Geospatial Data Abstraction Library extensions to R successfully loaded
 Loaded GDAL runtime: GDAL 2.1.3, released 2017/20/01
 Path to GDAL shared files: /Library/Frameworks/R.framework/Versions/3.5/Resources/library/rgdal/gdal
 GDAL binary built with GEOS: FALSE 
 Loaded PROJ.4 runtime: Rel. 4.9.3, 15 August 2016, [PJ_VERSION: 493]
 Path to PROJ.4 shared files: /Library/Frameworks/R.framework/Versions/3.5/Resources/library/rgdal/proj
 Linking to sp version: 1.2-7 

# When I updated rgdal the startup message from rgdal now says:

Linking to sp version: 1.3-1 

# ... despite the fact that I installed 1.3-4

That's never cause a problem that I've noticed, but I'm not even a moderate user of GIS so am not stressing the interlocking programs very hard. 

I then mounted the newer super-package 2.2 disk image from KyngChaos and ran the pkg-installer to see if I could break anything. Nothing seems to be broken, but the rgdal package still reports loading GDAL 2.1.3, despite GDAL 2.2 being the more recent version and the one to which the 'Current' folder-symlink is pointing. The PROJ framework now has a new 4B directory but the startup message for the PROJ.4 runtime is also unchanged.
