Here's the problem: some days ago I installed macports on my MacBook Air because I needed some c++ libraries but for some reason I wasn't able to use them. Then I upgraded my Mac to Mojave and the day after that I installed home-brew because I wasn't aware that the two cannot coexist. It did work well, so I wanted to uninstall macports but It wasn't possible because I had upgraded from high Sierra to Mojave so I first need to migrate macports to use its commands (even to uninstall it). The matter is: today I read that it's no good to have both macports and home-brew installed, so I installed home-brew and almost all of its files because I couldn't uninstall macports for the reasons above. Have I compromised anything by having both them installed for one day or is it everything like before now that I've uninstalled home-brew?
