Hi all I have a MBP 13" retina mid2014 I did upgrade the standard 128gb ssd with the corresponding OWC 480gb ssd. However since than it takes up to 3min till the MB shows the "moving startup bar" (sometimes does not start at all) It might have come from the time I installed the ssd as I did put it first in the delivered enclosure (specifically was warned not to do so, but did not read instructions properly) Also on the system info it says there is NO INTERNAL harddrive. I presume I deleted by accident some files when I was prompted to format this drive prior to installation. Any idea what can/needs to be done to rectify the problem??
