My MBP (13" mid-2012, OSX 10.9.5) has been slow from the very start as far as I can remember. By slow I mean that the spinning beachball pops up just about all the time and especially if I say want to surf the web while Adobe Lightroom imports photos from the SD-memory card slot, but also at other times when for instance I just go to a different menu or something in the same app, which is just plain ridicilous. I've got the standard hardware configuration (500 MB/5400 RPM HDD and 4GB RAM) and suspect the slow hard drive to be the reason for this though I still find it hard to believe it should be this slow! Then I read somewhere about defective HDD cables, but I'm not sure if this was an isolated case or if this is a production problem for this particular model MBP. Can anyone shed some light on this?
