iMac (late 2009) with Samsung 840 SSD & High Sierra


hi guys,

i've been running late 2009 27" imac samsung 840 ssd (replacing superdrive) on sierra. i've had persistent problems while booting 'prohibitory' symbol. second or third restart boots successfully. running disk utility reports no errors. unable find solution problem. clean install did trick while reoccur.

i've installed high sierra after installing little snitch , rebooting i'm hitting prohibitory sign again. imac boots sierra recovery partition unable see drive it's formatted apfs now.

ideas...

1) how can create high sierra recovery partition on 1 of other hd's in imac?
2) shouldn't 10.13 recovery partition have been created on ssd in first place?
3) little snitch causing 'prohibitory' boot issues?

appreciated!
