There have been reports of multiple-display issues with BIAB 2025 on the Mac.

Unlike others, you actually answered my questions instead of trying to make me read your mind. Thank you for that.

Although Apple is having multi-display issues on the Studio and M series Mini, your symptoms are not on my list of problems that Apple has yet to fix. I'm pretty sure that what you are describing is BIAB and not Apple.

Here are the current Apple issues:

Windows and icons open on the Right display shift to the Left display and vise-versa after the displays go to sleep, then wake up. Rebooting or restarting restores the original problem. Benign but annoying.

Displays connected via DisplayPort wake up every 15–45 seconds once they go to sleep. The only workaround is connect via USB-C to HDMI. This is the one I had to demonstrate in Cupertino before anyone would believe me. I still have my DP cables and test now and then to see it hasn't been fixed.

There are others.

My center display is the current 27" Studio connected by a USB 4 (TB3/4) or USB 4.2 (TB3/4/5) cable. Changing it from my main to a side display has no effect on the symptoms described above.
