Version 2.2.2
Review by NothingToGain

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.

Needs update for late 2016 Macbook Pro - Can’t really blame Blackmagic, but it maxes out at 2,000 MB/s. Runs great on my new Macbook Pro 15” (late 2016), but the write score is at around 1,950MB/s, and read just hits the limit at 2,000 MB/s. Would be nice to see how fast it can get!

Review by NotarySojac

Works fine on our 2008 MacPro running Yosemite, but not in SnowLeopard. - Not sure what’s up with these 28 one star reviews. Downloaded from the App Store with no trouble, launched with no trouble in Yosemite and is giving reasonable test results with al the drives on our 2008 MacPro running Yosemite. However on our MacBook Pros running SnowLeopard it crashed repeatedly. I went to the Blackmagic support pages (clicked the link on its page in the App Store) and found mention of a similar problem in their forums. Evidently Version 3 needs a library that SnowLeopard does not have, however by downloading and installing Blackmagic_Camera_Utility_1.7 the library gets put in place and the Blackmagic Speed Disk Test launches with no crashing.

Review by 30min download for 2 min intro

same as everyone else, doesn - 2012 MBP, ... core i5.. 10.6.8.... and my machine is extremely lean, not bogged down with loads of apps, programs,... nothing running in the background outside of the OS itself machine meets all the supposed compatibility requirements, but like most all the other reviews here, it DOES NOT WORK... it immediately "quits unexpectedly" when you try to open it.... downloaded, app didn't work... so deleted and re-downloaded and it's still completely non-functional

Does Not Work - Like many other reviews I will state it once again. This current update does not work, I’ve tried launching multiple times and it crashes. Currently running Mac OS Sierra this could be the problem.
