I just installed PoM on my 10.12.6 MBP
When I first launched it, it did not open the first-launch screen where it downloads xQuartz. Now, as I'm trying to download metatrader 5, it says "Waiting xQuartz to be installed." but it doesn't appear to be donwloading or installing xQuartz as it is taking forever with no loading bar or sign of progress.
Please let me know how I can install xQuartz, thank you.
