Looking for an opening trainer

I'm looking for a product similar to Chess Position Trainer to work on my opening lines. Unfortunately I have a Mac and that product only works on Windows. Does anyone know of an alternative? 

this is a good question

I am looking for a program that works well with endgame studies. I have Chess Position Trainer for my openings.

I'm not sure how this is relevant to my thread. 

Well I thought the subject was ''programs'' and not ''openings''. Anyway your thread itself doesnt seem that relevant considering the amount of replies lol

This is the Openings subforum, is it not? 

Unfortunately, it seems that there are not enough Mac users in the chess community for any popular openings training software to have been adapted for Mac. I've found a couple of software options compatible with my computer but none of them have operated in quite the way I had hoped. That's why I started this thread - to see if anyone knew of any alternative programs which might better fit my needs.

I am a Mac user and, unfortunately, I didn't find many good chess programs for Mac.  Seems like there are few.  Anyway, i have Shredder and Stockfish, Those are not specific for openings, but those was the best I could find.

Could you give a recommendation of which emulator to use?

Chess Openings Wizard is working on a beta version for MAC.

Thanks for the suggestion. I'll look into it.

I use on my ipad Chess Openings Trainer , i can use it for Openings , Tactics and Endgame .

I whish this program would come to windows or android , but the programmer only programs for Apple

You could try an old-fashioned opening book.

I was looking for an opening trainer myself for iPhone/iPad where I could enter my own lines and train them. Since I couldn't find an app I liked, I developed one myself: King's Cross. If you'd like to have a look, I'm happy to hear your feedback. So far it's only available for iPhone/iPad but not for Mac/Windows though.

Your app look very nice but why you made it available only for IOS10 ? I can't install it. 😞

Same here , so i have to see if i can install it on a friends device and see if it worth the claims it makes. i used COT (Chess Openings Trainer) a lot so i'm curious

I never understood how to use COT. Very impractical to work with. The problem to add new ideas at the time being you are training its killing my nerves. I want a program where I can train and experiment at the same time, saving or deleting lines and subvariations. In chess thinking process should be ready to adapt against every possible reaction from your opponent even if it's an inferior line. Studying ideas in the opening its more important than memorizing lines.
