Alright, well I switched over to a MacBook Pro from an HP probably 3 months ago. I had no problem with the transition except with SD Cards. With my old computer I used to be able to move .mp3s onto a blank SD card and play them in my car. Since i got a Mac anything i delete on this card does not actually delete. It will say 148 MB available but if you go to add something it says its full. Then i go into my car and the SD card is split into different folders, all the new stuff. then the next folder is all the stuff i deleted, but you put it in the mac and it doesnt show this other folder. I had the same problem with my phone Micro SD so i reformated it with the mac and now my phone will not read the Macintosh format no mater which i choose. Its super frustrating because this is the only thing that Microsoft was way easier with. Help
