I indirectly make a lot of use of GDAL which makes a lot of use of proj. I do all this on a new Macbook pro with Apple Silicon. I manage these things with homebrew. It was a tiny bit complicated to get homebrew running to take advantage of the new silicon but I’ve been doing that successfully for a month or so.
At some point in the past I installed proj@7 from homebrew. That’s now deprecated but I can’t seem to kill it on my system. Lots of brew uninstall and install/upgrade commands. I used locate in a terminal and attempted to delete all the files with proj@7 in their names. I’m currently have this set of exchanges gcn@MacBook-Pro-M1X Cellar % brew install gdal Warning: No available formula with the name "proj@7" (dependency of gdal). Did you mean proj? ==> Searching for similarly named formulae... This similarly named formula was found: proj ✔ To install it, run: brew install proj ✔ gcn@MacBook-Pro-M1X Cellar % brew install proj To restore the stashed changes to /opt/homebrew/Library/Taps/homebrew/homebrew-core, run: cd /opt/homebrew/Library/Taps/homebrew/homebrew-core && git stash pop Running `brew update --preinstall`... ==> Auto-updated Homebrew! Updated 2 taps (homebrew/core and homebrew/cask). ==> Updated Formulae Updated 1 formula. ==> Updated Casks Updated 4 casks. Warning: proj 8.2.1 is already installed and up-to-date.

I suspect this is not a gdal problem per se but something in homebrew I’m not understanding. Any advice greatly appreciated! Jerry Gerald C.
