KeychainCheck2
KeychainCheck2 is a macOS utility developed by Eclectic Light that diagnoses and repairs problems with the system Keychain — the secure storage mechanism where macOS and third-party applications store passwords, certificates, cryptographic keys, and other sensitive credentials. It scans for corrupted Keychain files, duplicate entries, broken references, and access permission issues that can prevent apps from authenticating properly or slow down login. Users typically turn to it when they experience repeated password prompts, authentication failures, or general system sluggishness traced to Keychain problems.

1 suggestionNo public information is readily available confirming whether KeychainCheck2 has been updated to run natively on Apple Silicon, nor is there clear evidence that the app is no longer maintained. Given that the developer (Eclectic Light) is active in the macOS utilities space, the best course of action is to check the official Eclectic Light website or contact the developer directly to ask whether a native Apple Silicon build exists or is planned. If you find that a native version is not available and the app is no longer actively developed, consider using Keychain First Aid built into macOS itself (accessible via Keychain Access utility in Applications > Utilities), which provides basic Keychain repair functions natively on all Macs including Apple Silicon models.
