Hi Everyone, Need some advice here. I just bought a new rMBP 13inch i5 2.7Ghz- 2015 model with 8gb RAM and 256 GB SSD : fresh install out of the box. It works quite fast once booted but the cold boot time is about 27 seconds from the time I press the power button till I see the desktop. Is this normal ? To be more detailed, after I press the power button, I get a black screen for about 8-10 seconds and then the white apple logo shows up against the black screen and hereon, its quire fast. My late 2013 iMac with 8gb RAM and 1TB Fusion Drive (Running Yosemite) takes about 14 seconds from the moment I press the power button till I see the desktop so I was hoping that this new machine would be faster..... Thanks in advance !!!
