DiskWarrior is a classic that goes way back. However, I use another tool called Cocktail and TechToolPro so I never bought it. Now I see that it won't support APFS drives and that Apple is essentially pushing independent developers, repair shops and the like out of business with their SoC architecture, which essentially amounts to converting everything — even desktops and laptops — into a mostly unrepairabe, non-upgradeble device. If any part of the memory, SSD or graphics card fails, the entire device becomes a brick. So clearly with APFS and Apple Silicone the stakes are that much higher for a software solution that will resurrect them from the dead when their internal recovery functions fail, as can happen in the event of a hardware failure. But what is the answer for developers like DiskWarrior? Apple is clearly sending the message with their T2 security chips, signed certificates for software, System Integrity Protection and other moves that they absolutely do not want anyone modifying any aspect of the device! (Just like Big Government, Big Tech loves to micromanage their users, while calling it "safety and security"!)
In conclusion, I thought I would download this software while it's still out there because I'm a curmudgeon and refuse to go with the subscription model for anything and everything. As a result, I intend to keep my old but working Intel Macs around for 32-bit app support and the simple fact that I OWN my copy of Microsoft Office 11, CS6, etc. But now I'm asking myself: Why should I pay over $100 for a utility that is essentially crippled under Apple Silicone/APFS? DiskWarrior ought to cut their prices in half and make it clear that users of M1/M2 Macs will not have the same options as their HFS+ counterparts. This software may be kneecapped, but I hope the developers will keep offering it because there will be thousands of people around the world keeping around Macs that no longer have Apple Care and can't be easily replaced. In that case, this product will be more useful than ever.
