Why on Power On takes long to show Apple Logo?
Does anyone know why it takes about 10 seconds (black screen) to show Apple Boot Logo in iMac 27 2013?
I got macOS Catalina on non-Apple PCIe SSD with adapter.
I’ve pointed out the Startup Disk in Settings as a Boot Disk - done reset and……… it was showing that Apple Boot Logo right away - but from shutdown - power up - it takes about 10 seconds to show Apple Boot Logo - which is very weird.
I got even macOS Catalina installed on genuine Apple HDD (without any PCIe SSD) and STILL same thing.
I had 27” iMac but 2012 with same non-Apple PCIe + adapter SSD and it was showing Apple Boot Logo right away.
I’ve hold D for Diagnostic and no errors at all.
I’ve done PRAM reset.
