Hey, guys.

I have a Late2013 iMac (2,9Ghz i5 / 8GB / 1GB video) running the SO in a external 1TB SSD and I never had speed problems. I use the internal HDD for storage only, there is no SO installed in... That internal 5400rpm is really a joke.

I was at Sierra (not the High) and decided to upgrade (not a clean install) to Mojave and after that, when I turn on the iMac it takes about 2 or 3 minutes to show the Apple logo(!!). At first I thought it was freezing in start screen and turned off the iMac several times until I decided to wait that long time and see... Than I realized it was not freezing, but was too slow.

So... I installed every thing again, in a clean install with a boot disc. And same thing happened.

After the Apple logo appears, it goes apparently in normal speed. But this delay on boot is not normal.

Any ideas?
