Chosen Solution
About three months ago I replaced the original SSD with a OWC 240GB Aura Pro X2 SSD, because the original SSD broke. When I start the laptop the starting sound can be heard two times. The Apple hardware test program states that there maybe a problem with the memory. But, there is no other problem. Can I ignore the error report or should I do something?
The only unusual thing that I could see on this one is that you used cloning software. While the was the standard modus operandi years ago, today we do a clean install of the system and then use MIGRATION ASSISTANT to restore data. You might give that a shot with just moving your data first, then test, then move your APPs.
I wouldn’t ignore the error! It sounds like your Aura SSD was not setup correctly or something needs to be investigated. What does the onboard diagnostics tell you for an error code? To run diagnostics restart your system holding the D key. Reference: Mac startup key combinations
