In the engine setup I saw no threads or cores.
In the Common Engine Options dialog you can specify 'Max nr of CPUs'.
There is one menue called engine match. How can I configure it?
E.g. Telling the gui to run 100 games from pgn position xyz and exchange colors after each opening.
You configure the tournament through the Match Options dialog (in the Options menu); the Machine Match menu item is just for starting / pausing / stopping the currently configured tourney or match. (This allows you to quickly start a 'shootout' between the currently loaded engines with your default match settings.)
Behind 'Default Number of Games in Match' you type 100 .
Behind 'Game File with opening lines' you type the name of the file with opening lines (or use the Browse button right of it to point it out).
Behind 'Game Number (-1 or -2 = Auto-Inrement)' you type -1, because you want the number of the game used as opening line to increment after each game.
Changing colors every game is automatic in a two-player match.
You can specify a Tournament File, select two engines and press 'OK' to start the match as a tourney that you can interrupt, and resume later (by clicking the tourney file, which records tourney settings and progress). Or when the engines were already loaded, you can just 'OK' without selecting engines and specifying a tourney file, and use the menu Mode->Machine Match to start the match. (You can also use that menu item to stop the match early, after the current game.)
How about tables bases on the Mac ?
There is a Nalimov Path text entry in the Common Engine Options dialog, where you can enter the path to the tablebases to be communicated to the engine. I must admit I forgot whether you can also use it for the other flavors of tablebases in XBoard; in WinBoard you can, by typing the flavor name before the path, like "syzygy:/usr/share/games/chess/tablebases". I would have t check if that works in XBoard. If not, you can always run XBoard once from the command line with the option
-egtFormats syzygy:PATHNAME
Is there a button I can adjudicate the running game when I see it will end in a draw or a position is hopeless ?
Well, it is a menu item, rather than a button. Look in the Action menu, for 'Adjudicate to White', etc. You can of course also let the GUI adjudicate automatically, if the score gets too high, by setting a WIn/Loss Threshold in the Adjudication Options dialog.
