Catalina isn't supported
I have just restored my Mac to give to my granddaughter & can't load any of the apps because it requires Mac OS 12.3 or later!!
iMac 21.5″, macOS 10.15
When you say "load" are you referring to the apps as part of the dataset being migrated or are you trying to actually install old app versions that were downloaded files previously installed. on the old Mac?
