Have you ever tried this on options on futures? It's not same on my side.
desktop is desktop, not mac vs win.
go to left upper corner, type for example, es, pick e-mini s&p 500 futures, select the month. in the middle window, second menu on the top is option chain, then you see the typical option table, right click buy or sell, the trade panel on the right has the analysis and submit, as simple as that.
only issue i have with the new desktop is that it couldn’t load more than 100 symbols from my watchlist. something to get use to.
