| Happy New Fix! |
Just a quick post: macOS 15.3 is now out, and with it, a fix for the broken replicator. As such, macOS copying will work again with Erase, then copy backups. No update to SuperDuper is necessary (but feel free to install our v3.10 Beta 2, below). Note that this does… |

| Beta-ing |
Well, although we can't do anything about macOS 15.2 breaking the replicator, we can continue to work on the things we have control over. And, in that spirit, here's Beta 2 of SuperDuper! v3.10. Minimal Changes Not a lot new in this version, actually, but it's gone through additional weeks… |

| You’re a Mean One |
macOS 15.2 was released a few days ago, with a surprise. A terrible, awful surprise. Apple broke the replicator. Towards the end of replicating the Data volume, seemingly when it's about to copy either Preboot or Recovery, it fails with a Resource Busy error. In the past, Resource Busy could… |

Welcome to the first Beta release of SuperDuper! v3.10—the cycle begins again. For those who don't know the drill: if you download and install this Beta release, you will automatically receive subsequent Beta releases until the final release of v3.10. Once that comes out, it will also be offered, and… |

| SuperDuper! v3.9.1 Now Available |
For a while I thought that, maybe, I'd somehow managed to delete the v3.9 blog post. But, it looks like, somehow, I didn't write it, maybe? I don't even know any more. No Matter Well, in the end, it's OK, because the semi-inevitable point release is out—v3.9.1—and fixes an issue… |

| Quick Fix |
Not much to say, other than "we fixed a bug". SuperDuper checks the version of the OS on a give drive by checking the SystemVersion.plist, which is stored in /System/Library/CoreServices. On some systems, we've found that that file is missing a value that we assumed would always be there. That… |

| Turntable Listening Experiment and Wrap-Up |
A few weeks ago, [The Tracking Angle][tracking] posted a YouTube video comparing two turntables, using the same arm, cartridge and phono preamp.

| You Got Culpa on My Mea! |
One of the problems with supporting versions of macOS going back to 10.10 is that it becomes harder and harder to test older versions...and that's complicated further by Apple silicon, since you can't run an Intel VM on Apple silicon...Rosetta won't work. Unfortunately, in v3.7.3 and v3.7.4, this has caused… |
