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.

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.

Reports incorrect speeds on M1 Thunderbolt 3 external SSD

When I first got my M1 MacBook Pro the software reported my external Thunderbolt 3 SSD speed correctly. After the update to 3.3 it now only reports the write speed as 1300 MB/s instead of the previous 2300 MB/s. At first, I thought the drive was faulty but I tested on my i5 MacBook Pro using version 3.3 and got 2300 MB/s. Finally, I actually copied 100GB of data onto the external drive (Thunderbolt 3 4x PCIe with WD_Black 750) and the speed was slightly faster on the M1. The conclusion is that the software does not accurately report write speeds on external drives on the M1 Macs.
