![]() ![]() Prevents a kernel panic when a SoftRAID disk is connected via a USB-A port on an M1 MacsĮver since the M1 Macs shipped we have known about a kernel panic that occurred when a SoftRAID volume on a USB disk or enclosure is attached to the USB-A port on these new Macs. Users must still unmount SoftRAID volumes in the Finder before erasing a disk using Disk Utility as Apple’s program does not understand the connection between SoftRAID volumes and disks. The Mac would also hang when the user attempted a shutdown or restart, requiring a forced restart by holding down the power button.Īfter trying many different techniques, we finally figured out how to get macOS not to enter this state. If the disk remained attached, any application which subsequently tried to access the disk would hang (e.g., Disk Utility or SoftRAID). They could then force quit Disk Utility, but the Mac was left in an unstable state which did not get fixed until the Mac was rebooted. Since around macOS 10.11, a user could get Apple’s Disk Utility program to hang by selecting a SoftRAID formatted disk and erasing it. Prevents Disk Utility from hanging macOS when erasing a SoftRAID disk The following is a detailed list of what we fixed in this release. We also had help from Apple engineers understanding some of the undocumented aspects of macOS. Our testers were focused on duplicating the difficult bugs, some of which only a few of our users had reported. The work on SoftRAID 6.2.1 started last summer and involved many months of testing, both at our main development location in California and with our hardware team in Taipei. ![]() It has been four months of research, testing, and coding to fix these problems. SoftRAID 6.2.1 is the result of one of these efforts. SoftRAID has been shipping since 2003 and during the past 2 decades, we have periodically switched gears to focus on fixing these difficult bugs. With any software product which has been shipping for a long time, it is important every so often to stop working on new features and instead spend time fixing difficult bugs and performing extensive testing. ![]()
