Practicing Unlimited Time Account for Mac

Hello, I’m seriously following the school of pipsology and would like to start training with a demo account somewhere. Whereas I learned to keep practicing for a long while (and this is my intention) I haven’t yet found a broker who’ll offer a practicing account for unlimited time. The second issue is about the platform: I see that MetaTrader is probably the most one used, though it is only available for windows while I have a mac computer.
Can anybody eventually give me a hint?

Thank you in advance.

Windows emulator on mac? Oanda?

I’ll consider a win emulator! Thanks!

I’ve opened a practice account with Oanda! Their FXTrade applet seems attractive.
