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.
Two seperate approaches to try: 1) Strip down your application and OS environment to only the pure essentials necessary for trading, including removal of any third-party security tools, some of which can contribute to these Guard_Type_Mach_Port type errors. If this fails, a more thorough version of this approach starts with reinstallation of the OS and apps from scratch. or, 2) Run the IBKR Desktop Win 64-bit client on Win11 under Parallels for MacOS. Parallels provides an ecumenical environment where you can run Win apps as though they were native Mac apps -- can seamlessly cut and paste between OSs, &c. The Win11 environment essentially becomes a VM or just another window on the MacOS desktop. For the IBKR client in a production environment, if you have a version choice between (presumably stable) 'latest' and 'beta,' for god's sake avoid beta.
I like the ibkr android app, no idea about apple devices. Not much for modelling, analysis, greeks... I use TOS (delayed) or Orats for that. But I find the app fast, stable and reliable for orders, monitor, open and close.
IBKR Desktop is making people love TWS these days. And they have been shitting on that abomination made in Java for decades. Imagine the number of bugs that IBKR Desktop must have for people to start loving the piece of crap that TWS is.
