WOTLK on MAC 32 bit ???

Hello!

Is there any ways to connect Onyxia BC realm via a 2.4.3. client? If I copied the realmlist to logon.warmane.com it says it is unable to validate game version.

Thank you!

PS: if I can download any WOTLK client for 32 bit mac os High Sierra, I would like to play WOTLK on warmane too..
But I Cant find any client for WOTLK (mac)...

No, you can't connect to Onyxia with a Burning Crusade client, it requires a 3.3.5a client.
