You are having trouble downloading and viewing system reports on your Mac. The download file looks like computer code.
This typically happens if you are using a Macintosh computer you choose to Download the report in an Excel format.
The Excel format is actually in an XML (eXtensible Markup Language) file that Microsoft Excel knows how to convert on the fly to display as a spreadsheet. Most Mac's and many Windows computers will open the XML file in a web browser, and the results are far from desirable.
If you are a Mac user, the best file format choice for you is the CSV (comma-separated values) format. This file will open without problem using the Apple application "Numbers."
If you are a Windows user and are having problems, please see this Help FAQ.
