I found one possible reason for Snackr crashing on the Mac: it seems that if CoolIris for Safari is installed, it interferes with Snackr/AIR (specifically, the input manager it installs seems to cause the problem). Try uninstalling the plugin (in Safari, do View > Remove CoolIris) and see if that fixes the problem with Snackr.
Not sure this is a bug I can fix in Snackr; it seems to be some interaction between the input manager and AIR. I might just have to note that Snackr is incompatible with Safari CoolIris. (CoolIris for Firefox seems to work fine.)
