For all those having the “Read Only” issue... - This excellent product works precisely as advertised. If, like BBurr55, you think it doesn’t function because you get a message saying your drive is "read only” and you need to pick a drive with Read/Write privileges, you might be forgiven for thinking that’s nonsense because, "I’ve been reading and writing to them both before and after the test.” You might be forgiven for thinking that, but you’d still be wrong. Mac example: Though you can read and write to your external drives, that’s because the computer knows you as Administrator (or “system"). Open the Finder and go to the external drive you want to test. If you have right-click enabled on your mouse, do that or go FIle>Get Info or Command+I . When the Info window opens you’ll see at the bottom that under Sharing & Permissions “system" and “wheel" are set to Read & Write, but “everyone" is set to Read only. This is by default to keep hackers and malware from writing to your drive. It sees the App, Blackmagic Disk Speed Test, as “everyone” To run the test click the lock in the lower right-hand corner of the Info Window and enter your password to unlock. Change “everyone" to Read & Write and then close the window. You can now run the speed test. You should change the settings back when finished for security. Great App, but judging by the complaints you might want to warn about this in advance. Thanks!
DOES NOT FIT WINDOW ON MACBOOK AIR 11in - The program uses non-standard windowing which makes it impossible to view the whole window on a MacBook Air 11in. Useless.

Great until latest update - New app update does not even open on MacOS 10.12.5. Crashes instantly. Reinstall fresh did not help either.
To Developer - Please don’t push a version to App Store if you didn’t run your application on your bare macOS installation.
Application Does Launch, but not when clicking open once installed - I’ve launched from launcher and it did start. I did try once installed to click on open and it does not open as it would close immediately.
No longer working after update - Just updated this app and now its no longer working, was working perfectly before.
Doesn’t even open - The app will not even open.
