Placement of internal HD on startup screen

TidBITS Talk

My MacBook Air M3 (macOS Sequoia 15.7.5) has started moving the icon for the internal hard disk down one slot on the startup screen. (By “down one slot”, I mean that I can move the icon from its location after I wake the computer to a position a bit higher on the screen, then select View > Clean Up Selection, and the Finder will happily put the icon in the top right position on the startup screen.) As far as I can recall, this started in the past week or two and the icon is repositioned every time I wake the computer. (One time, a screenshot occupied that position and the Finder put the icon for the internal hard disk in the next available slot down.)

Here’s a bit more detail that I think should not be important. I run the MBA in closed clamshell mode with two displays. The startup screen is a portrait-oriented display to the left of a landscape-oriented display. Both displays are connected to a CalDigit hub. None of that has changed in months.

I installed macOS Sequoia 15.7.5 on March 26, and maybe that is when this behavior started.

How do I get the Mac to leave the icon in the top right position on the screen? Thanks.

I have a similar setup and the same issue but also the external drive icons move to inconvenient locations at startup or when closing the MBA for clamshell mode. There doesn’t seem to be a way to fix it.

Thanks. I have not had the issue with desktop icons (drive volume or otherwise) moving around, but I hardly ever open the clamshell. I do have windows move from the secondary to the primary screen if I have any open when the computers goes to sleep.
