Customer Reviews

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.

Problems Running on Snow Leopard

Will not run on Snow Leopard for me. I rated it a one because it says it will run on 10.6.6 but doesn't and someone has reported the problem here with a workaround. Having said that the developeer should have addressed this and repaired it by now IMO. I don't like this rating system though as my rating of one is not a statement that I don't like this product, just that it fails to run on Snow Leopard. It seems fine on the other Mac OS systems I have tried it on.

I am hoping I'll be allowed to raise this rating after they provide a fix.

Working fine on i7 Retina iMac

Maybe Blackmagic updated this software in the last few days, but I had no issues running it just now on an late 2014 i7 Retina iMac. Have used this in the past and this version worked just as well as it always has.
