The only performance reports available for a portfolio are by account, and not the entire portfolio. I have spoken to your chat person to try and obtain this and I was told it is unavailable in Quicken for Mac. I would be very helpful for a great many customers to provide a single IRR for an entire portfolio and NOT by account. It IS available in your Quicken for Windows version which I no longer use. Please add this to your "to do" list for Quicken for Mac.
Thanks
