MP 1,1-5,1 Random SuperDrive and BluRay Drive Eject at Boot?

[calmacfan]

I have the original SuperDrive and a LG BluRay Drive installed on my 2012 Mac Pro. Every now and again it ejects both the optical drives at boot. It seems like it may be tied to SATA drive positions. I've noticed that moving the bay location of my original WD Black Series Hard Drive seems to remedy it on the next boot but it seems pretty random. Any ideas why it does this?

Some mouse or trackpad gives a button pressed signal on boot. Had this with a wireless mouse transmitter.

Interesting. I'm not using a Trackpad just my Apple Magic Mouse 1 and Apple Bluetooth Keyboard which both seem to be working great. I have not other peripherals plugged in either. Seems really random. I am using OpenCore 0.5.9 BTW so I wonder if it related to how that is figuring the boot picker.

My guess is still something "presses" the mouse button on boot time.

This is if you dont know - the official way to open the tray in a panic mode.
