My accountant filed my 2016 return via the Ufile Windows app and has provided me with the *.u16 file as I wish to complete my tax return for 2017 via the online tool (as I use an iMac). The file was sent to me zipped with a password. I unzipped it successfully and am trying to upload the *.u16 file online but get the error message it could not be uploaded, try to use password if encrypted, etc... Tried the password from the zip file, tried without, still won't work.
Does the fact I'm using an iMac cause issues? Or is it possible was the file somehow corrupted during the zipping process?
Any help is appreciated.
