Hey everybody, I upgrade my iMac (Blade SSD + SSD + RAM) and I have a problem. My iMac doesn’t start up properly but only if I press PRAM reset at the start and then he starts properly. I exclude it’s an hardware problem, but I see it like a software/firmware problem.
Suggestions?
Is this a good question?

Go under the Apple icon to System Preferences > start up disk > unlock it > select the start up disk and close and restart.

Recovery and Setup are installed on the new Blade SSD I put in.

Even still run the onboard diagnostics. Reboot and hold the D key. Did you get an error message?
