Using a symlink to easily view the AEM log on macOS +10.12 in the Console application (without having to manually find/open the log file) won’t work anymore, it requires a hard link:
brew install hardlink-osx
mkdir ~/Library/Logs/AEM
hln <PROJECT ROOT>/AEM/author/crx-quickstart/logs/error.log ~/Library/Logs/AEM/<PROJECT NAME>.error.log
open -a Console.app
Anytime you want to view the log, it’s at Reports → ~/Library/Logs → AEM → <PROJECT NAME>.error.log
Note: When the log file is cycled out (done by AEM daily) the hard link will break – haven't found a workaround for this except creating the hard link again – probably something that could be done as part of the AEM quickstart/start script.
