I am very frustrated. I have a TON of work on my Macbook Pro, but it's old and I can't afford a new one. So, I purchased a pc laptop and now I am regretting it big tiime. I NEED to be able to transfer all of the work on my Mac to my new PC, but NONE of the TEN external hard drives that I have tried will READ AND WRITE on BOTH machines. I need to be able to plug an external in my Mac, copy files to it and then plug that same external into my PC and put move those files to my PC. I have even tried moving all of my files with a flash drive, since both machines will at least recognize it. Even THAT doesn't work. The files that I put on the flashdrive with my Mac ONLY show up when the drive is plugged into the Mac and the files that I put on the flashdrive with my PC, ONLY show up when the drive is plugged into the PC. How is it possible to transfer ones Mac files to a PC, when you buy an external that works ONLY on one platform or the other? Am I trapped into only buying new Macs for the rest of my life?
