We are pleased to announce the release of SD Notary 2, the application for notarizing applets and other files. SD Notary 2 replaces SD Notary, which is still available but uses a method Apple intends to discontinue in the near future.
We advise all users of SD Notary to download and use the new application, which is based on Apple software that is faster and more reliable. The exception is those running versions of macOS before 11.3. Just be aware that those older systems will soon lose the ability to notarize for good.
SD Notary 2 is free, and requires macOS 11.3 or later. The full requirements and other details can be found here: SD Notary 2 Release Notes.
