MPG: I’m using it on macOS Monterey on my 2019 Mac Pro. I also used it with the 2021 MacBook Pro M1 Max, with no issues. Indeed, the SSD speed tests for the MBP M1 Max were done with diglloydTools DiskTester. I am unaware of any macOS Monterey-specific issues.
Apple is likely to break the old APIs used by diglloydTools (DiskTester, MemoryTester, IntegrityChecker) at some point, but from what I can tell, there is no way to rewrite it for full functionality, so when it’s done it’s done. But for now it works great, as always.
As for IntegrityChecker, I strongly recommend migrating ASAP to IntegrityChecker Java, which is faster and more capable, and cross-platform, running on just about any macOS, Windows, Linux/*nix, NAS, etc.
IntegrityChecker Java is bundled with diglloydTools. There is no separate purchase option.
