Sad news: most of Alpha's functionalities which rely on AppleEvents fail on Mac OS X 10.13 (aka High Sierra).
As a consequence: one cannot open a file from a *Fileset* or from the *Recent Files* menu, one cannot use the *[edit]* proc, one cannot send a string for evaluation in R, one cannot use Excalibur for spell checking, etc, etc.

Technically, it seems that this is caused by changes in the aegizmo syntax: the API function *AEBuildDesc* now reports errors for strings which used to work on previous versions of the operating system. I'm currently investigating this issue which will require changes in Alpha's core, in the AlphaTcl library and in the tclAE extension. 
So, if Alpha is vital for your work, I'd recommend *NOT* to upgrade your OS to High Sierra until version 9.0b4 of Alpha is released. Note though that only the functionalities based on AppleEvents are currently impacted: the rest of Alpha works normally.
