.xls file attachments in Gmail opens, by default, with Numbers I am using latest version of OS X, whenever I want to download an .xls file from email attachment, it opens, by default, with Numbers and the file is not downloaded on my machine. How can I change this default behaviour?
Right click on an Excel file.
Click: "Get Info"
Set the "Open with:" selector dialogue to whichever app you choose.
In the "Open with:" section, there is "Change All..." button to change all files with the same extension.
