Converting PEM file to PKCS12 or PFX for the MacOS (Not Mac OSx)...

[Auteria Wally Winzer Jr.]

has anyone converted pem files into pkcs12, pfx, or der format explicitly for the MacOS versions 8.5 and above? i have 3 macs that needs CA's loaded.  if anyone has done this by all means give me the lowdown. i really appreciate everyone's efforts in solving this major issue, one being the CEO!   thanks!   wally winzer jr.
