Ratings and Reviews
Works fine with High Sierra
Was uncertain about using this given some of other reviews suggesting problem using this with High Sierra. But I installed it on a 2016 MacBook Pro and a 2013 Mac Pro both running High Sierra and the software imnstalled and ran fine on both. Gives easy and clear results. Very helpful when running a range of drives connected to both Macs.
Crashes from App Store, Runs from Launchpad
The ‘crash on startup’ bug that others are reporting seems to be limited to launching from within the App Store screen. If you click the ‘Open’ button from the App Store window after downloading then the App crashes instantly without any warning or eror message. If you close the App Store window, open Launchpad, and run it from there, it seems to run fine.
Drive broke after using this
I would be very wary when using this.
I used this on a brand new WD HDD. It had been working fine for the week since I had started using it, but the next time I used it after trying to find out the disk speed using Blackmagic Disk Speed Test, it failed. It won’t read or write, nor will it mount to my Mac or a Windows PC. I have tried various methods butthe drive is still dead with a lot of GoPro footage on it. RIP.
I see it as too much of a coincidence, so be warned, do not run this on a drive with anything important on it.
