I see some very initial good work and app specific features in Speed Test for Mac. If your bandwidth problems prevent you from accessing the usual web-based tests, you want an app on your Mac to test your bandwidth. Note that a trial version is available at the developer's website.
Problems:
- Some of the GUI titles overlap.
- The speedometers can't accommodate modern bandwidth speeds. My results pinned way past the red.
- The full history graphs leave out ping results.
- You can't print or save anything. But note that the full history graphs collect all your test results over time.
Meanwhile, setting aside the free vs pay, ads vs no-ads issues, there is a website that has the single best results output I've seen so far, and the site uses only HTML5 in its implementation. That site is:

I prefer it over all others because it..
• Provides excellent live graphing of up and download results over time. I don't know anyone else who does this, yet. Documenting changes in bandwidth over time can be extremely useful.
• Provides several file size tests. This allows you to see whether your ISP service is providing full promised bandwidth over time or cheating by providing merely burst bandwidth.
I collect screenshots of the result graphs for comparisons. It helps me sort out whether I'm experiencing bandwidth traffic jams over time, the stupid squirrels are chewing on my ISP's cable again (which sadly has been a problem where I live), or some other problems.
Perhaps as Speed Test for Mac matures it will improve, provide more detailed results, add printing and saving.
