I have been able to resolve the Migration Assistant problem from my PC to Mac. I'm so relieved as I was giving up on being able to find a solution to my problem. I decided to start from square 1. I deleted the 2 accounts that were created on my previuos attempts of Migrating all files from PC to Mac using ethernet cable.
Once I had deleted those accounts I started again from the beginning to connect PC to Mac with an ethernet cable & followed the prompts from both computers using Migration Assistant & I started seeing my files beeing transferred from PC to Mac. It took 3hrs & 36 minutes for all my PC files (music,videos,documents,photos...).
I was still apprehensive as to what the end result of process might be. Once the process was finished. I disconnected the ethernet wire from my Mac & logged out from my Primary Mac account & was able to see a new account called 'User'.
Once I was able to login into 'User' account I found all my PC files using Finder. Every file was placed in the right folder on Mac. My Music folder has all of my music files. I can play all of them on my Mac. Those with mp3 format will open with iTunes. The others with WMA format will open with QuickTime. I still need to find a way to solve how to convert the WMA Files to MP3 on my Mac. But for now I'm comfortable with having all my PC files on my Mac. Now I just need to tweak things & I'm sure will need help in the coming days/weeks. Hope you can be of further assistance. Thank you again for your help.
