I'm running Mac OS High Sierra, and I have never had a problem installing mods – if anything, it's easier. Just create a new game directory and do all your crap in there.
I'm having the same issue. I'm running Minecraft on MacOS 10.13.3, Java 8 v. 161. My game crashes immediately after launch, and only when loading 1.13 snapshots. The crash does not leave a crash report in /crash-reports. Upon using the launcher log, both Minecraft and the Launcher immediately crash. I'm guessing a problem with the most recent version of Java?
