...screen only shows a file folder with a question mark.

Hi Brian:

Welcome to the Audiophile Style forum—and thank you again for your purchase of our unique Mac mini DC-conversion/Linear Fan Controller Kit (MMK).

@pl_svn is correct: The flashing icon you see means the boot ROM can not see a bootable drive.

 

In the 2012 Mac mini Apple’s propriety SATA drive cable has a funny flat square connector with a rubber pad on top. It presses down onto the logic board, and then the upper edge of the crescent-shaped plastic heat-pipe shroud is supposed to keep the connector from popping up—which is exactly what has happened in your machine to keep the drive from being seen.  Please check and correct that and I am sure you will be back in business.

 

If you continue to have difficulty, then please telephone and I will be glad to assist.

Happy Monday!

Next question/recommendation. I have the original Regen and have installed the MMK using a Jameco power supply. Any suggestion on an upgrade path? Iso Regen or JS-2 first?

 

BTW, this upgrade is ridiculous bang for the buck. Immediate and readily apparent improvement.

 

Hi Brian:

Glad you got it working!

The best bang for your buck next upgrade (at least in the UpTone sphere) will depend upon overall context of the Mac in your system.  How about giving us a call later this week and we can chat about your options?  Tomorrow (Tuesday) is crammed with our packing and shipping another dozen JS-2s out, so anytime Wednesday or beyond would be great.

Phone is: 1-209-966-4377--after 9:00 a.m. Pacific time please.

Thanks,
