I've spent a few hours putting together a couple of scripts to ease our pain.
The first is a diagnostics script - it's fairly straightforward but can give a good quick snapshot of what ails you. Mac OS X 10.9 (Mavericks) or more recent only, please! You'll find this at:

And if you're scanning this forum with the intent of installing Lich on your Mac OS X (again - Mavericks or more recent), you'll be even more pleased to discover:
http://bit.ly/GSLichInstall
These two scripts should greatly help ease some of our pain. Instructions (details on how to use, etc.) for those who may need them can be found at:

Have fun! And let me know if there are any issues.
