Migration assistant

My migration assistant has stopped working on both my desktop and my laptop since I upgraded to OS 10.15.6. Has anyone else experienced this problem and does anyone have any suggestions? Thanks. Fred.

Migration Assistant is not an "automatic" function. Rather, it is a function to import data from one computer to another.


Things that would cause problems for it:

  1. Importing old incompatible applications.
  2. loss of connectivity between the computers.
  3. trying to import data from a newer operating system.
  4. Lack of space to migrate the data. Note your total imported data should not exceed 85% of the capacity of the computer coupled with the existing data on the system. Simultaneous running of background backup programs such as Time Machine may create a problem for this, as it won't know which files to migrate. Turn off those background programs from Apple Menu -> System Preferences before running.

is a link to Etrecheck, a program that helps you find Launchdaemons which are running in the background which could prevent the migration assistant from running when chosen.
