Always boots Startup Manager

Same problem here.

I have a new Mac mini (2011 - no optical drive) and it always boot with the startup manager.

I use it as HTPC so no keyboard, no mouse, no bluetooth accessories....

Have you had any success on this? I am looking into a simmilar problem for a client also...

I dont think that is the answer, out of interest is this happening when you "restart" or just power on, and if its just a normal power on, is the machine turned off at the wall before hand, of just swithced off normaly with AC power still connected?

This only happens to my cleint when he turns it off at the wall also, and powers on,

Interesting, thank you for that info, ill continue my research, I will update you if i have anything to add,

one thing we tested what the removal of Bluetooth devices, Magic Mouse, Track Pad etc, have you tried this?

I belive it could be a possible firmware issue, which would envolve an EFI restore, then update again, I would NOT suggest you try this at home, but bring it into an AASP or Genuis bar.

Any news on this issue??

Have the same problem with by new Mac mini 2011.

Almost every start ends in the Bootmanager wher I can chose between

HD SSD and HD Recovery disk.

Has anyone found a solution to this problem? I just set up 6 mac mini's and each one has this issue. I've set up 100's before this and have never had this happen. Any advice would be greatly appreciated.... I have tried multiple fixes with no luck -

Reset PRAM/NVRAM

Select Startup disk

Wipe HD and reinstall OS

Repair permissions and repair disk in target mode

etc....

Thank you for any response...

So I may have found the issue.....

You need clean power. Wherever your system is plugged in seems to be messing with the PRAM/NVRAM settings on power up. We resolved our power issues and I went back to startup disk and selected my Mac HD. Rebooted 4 times with no issues. Did the same on the other 5, all work now. The power seems to have continued to scramble the memory. Now the mini's work fine.

Solution:

Try different power sources and set your startup drive in preferences again...

Hope it works for you as it did for me.

Hello,

We had the same issue and also determined it was power related (after having read your post, thanks!).

In our situation, there is one circuit which we determined is to blame. Other circuits in the office do not cause this issue - unfortunately, the circuit with the issue supplies juice to two offices, so this is not good.

Question - what do you mean by "clean power"? We have a (basic) circuit tester, which test for Open-neutral, Open-hot, missing ground, hot and neutral reversed, etc and our outlets all pass that basic test. What, specifically, was the issue with your power? We naturally want to know if we have a safety concern.

Thanks,

Have the same problem with by new Mac mini late 2012.

Always boots from shutdown in Startup Manager, no from reboot,

any news please?

I wonder if anyone has any answer in this now long dormant thread?

I have a recently refurbished (by me) 2007 Mac mini running OS 10.6.8 and I cloned the original HDD to an OWC brand SSD, which I installed along with a RAM upgrade. I also did a clean install of the Snow Leopard OS from the DVD, and then downloaded and installed all updates.

The **** machine boots in Startup Manager no matter what I do, the SSD has been designated the start disk in Sys Prefs, the PRAM and SMC reset etc... still the machine starts with the screen wanting me to click the SSD as the startup disk even though there are no other bootable disk choices, thats the only one.
