Successfully Transferring Data to a Mac:

A. Viruses:

Malwarebytes searches for malware(short for (malicious software) and spyware. Those make your Mac act in a mislead manor. So scan with it, and remove what is found from the quarantine. It is created by longtime users of these forums making it the only reliable Security Software for a Mac.

2. Malwarebytes Uninstaller

C. Corrupt Files:

Migration Assistant will transfer everything that can be transferred.
