Permissions problem files and folders after Migration Assistant

Good day,

I had issues with my MBP2011 it had Sierra beta + all the updates after, finally probably had the latest version but it was very slower than before. I decided to format the SSD and then install Sierra from a USB.

Success.

I had a backup with Time Machine. I decided to import only the data and files. It finished but created a second account named the account that I had before.

I am now trying to move the files and folders to my "new" account and then delete the imported account.

I have tried to set permissions to read and write, I have tried to use the /users/shared. Nothing is working. Some files and folders keeps the previous owner permissions and I can't open folders, etc...

What is the best way to move the files back to my new account? (Without using an external HDD, I do have one but I would have to make space)

I would like to be able to do it within the macOS itself.

Thanks for all the suggestions!

Oh well, I got around it by copying it to an external HDD. Thanks!

 

Thanks! Actually it didn't work with the HDD. I had to manually change the permission on the folder and using the little gear icon, apply to all subfolders/files.

Thanks!
