The MasterCook.com web importer has always saved the recipe to an online cookbook. That will never change. We have many customers who do not even have a Windows computer, and everyone uses the MasterCook.com web importer including those on Mac computers, Chromebooks, Microsoft Surface tablets, all other tablets, and phones.
There was a Download button in the web import window that appeared after the recipe saved to your online cookbook. That Download button was only for version 14 users like it said. That Download button corrupts cookbooks in MasterCook 15 and MasterCook 20 and confuses our customers, so we removed it.
You are supposed to sync your cookbooks with MasterCook 15 and MasterCook 20. Please read this article: https://support.mastercook.com/hc/en-us/articles/216898726-MasterCook-Synchronization
If you were using the MasterCook 14 Download button, your cookbooks will not sync properly. You will need to clear your account and start anew with syncing as explained here: https://support.mastercook.com/hc/en-us/articles/115000151746-Clear-Recipes-from-MasterCook-com
If you would really prefer to manually download your recipes from online to the program on your computer, that option still exists. After importing a recipe the web importer continues to give you a link to see the recipe that was imported into your account. Click on that link to view your online recipe. You can then use the Download link to download that recipe as a file to the computer and then open that file to import it into a cookbook in MasterCook.
You should NEVER sync and download though. You must do one or the other and never both.
