Q: boot menu not showing
Hi.
I have a "souped up" Mac Pro 2010 with two SSDs, one for Mac OS X and one for Windows 10.Everything has been running really well in the three weeks that I have had it, but when my Apple display died, I purchased the iiyama ProLite B2783QSU-B1 and have it connected via HDMI.
Until last night, it spent it's first few hours out of the box happily displaying the boot menu so I could choose between Mac OS X and Windows 10. The boot menu was really low res, not that it bothered me, but since last night, the iiyama ProLite won't show the boot menu, so I press the right cursor key once for Mac OS X, and just enter for Windows 10.
I'm mainly ok with that, but am curious.
Is there a way of forcing the boot menu to be a higher resolution? Has anybody else come across this?
Thanks,
Sarah

Hi,
You can't change any of the boot menu settings, and this issue likely coming from the display, as the Mac Pro automatically detects, like all HDMI devices, the resolution of the screen.
If you do not find any solution to your problem, I suggest you try another HDMI monitor, and if it works normally, try contacting iiyama about fixing their display.
I can however suggest that instead of bringing up the boot menu each time, you change the start-up disk in each OS :
- When in MacOS and wanting to go to Windows, go to System preferences : Startup drive, select the Windows 10 drive and select "restart".
- In Windows, (install the Bootcamp assistant if you have not done so) and right-click the bootcamp icon at the right of the task bar, and select "Restart on OS X"
I know this doesn't solve the issue, but it is a workaround.
