I am experiencing the question mark folder error after few hours of on-time. Internet posts point to the hard drive cable being the issue which led me to here. Instead of buying this line cable from this link: Mac mini A1347 (Mid 2011-Late 2014) Upper SATA Cable Would it be fine to order this kit? Mac mini Dual Drive Kit
It’s a matter of which bay the boot drive is in and what you have for drives. Update (09/13/2021) @dennyho93 - Best to check as Apple did both ways ;-{ Follow this guide to Step 5 Mac mini Late 2012 Logic Board Replacement You just need to lift the fan up to check the cable connections
BTW - Here’s the other cable: Mac mini A1347 (Mid 2011-Late 2012) Lower SATA Cable The kit offers the needed tool to open the system, that U shaped tool, needed drivers & screws.
