Question on TM Backup

[kitjv]

I just completed my initial TM backup on an external HD. When I attempt to open an application on the external HD, I get the following error message: "An unexpected error occurred (error code - 10657)". This seems to be the case with all applications. However, I can open documents just fine.

Can someone please help? Thank you.

IF you google( error code 10657 on a mac) there is a different solution for both
kitty and probo.

Everytime time machine backups a data into our external HD it saves it into a format that only Time machine can read. So if you enter Time machine and click on an application it will open however if you do it manually and went straight ahead to your backup file and opened a file or the app from there it is most likely that you will encounter this error.
