The Big Sur update introduces a number of major changes in macOS. One of them is disabling of the Network Kernel Extensions (NKE) API, which Proxifier for Mac v2 uses. The new Network Extensions API has been introduced to replace it. We have rewritten the network part of Proxifier to adapt to this change. Together with other improvements, Proxifier for Mac v3 has been released.
Proxifier for Mac v3 requires a new license. Upgrade options depend on the date of your v2 purchase.
If you purchased Proxifier for Mac v2 on or after:
You can extract your current v2 key using one of the following commands in Terminal:
Proxifier for Mac v3 includes the File->Import v2 Profile... menu command, which allows you to import configuration from v2. Alternatively, you can save profile to a file using File->Export... in v2 and then import the file using File->Import... in v3.
Because Proxifier for Mac v3 runs in a sandbox, it is technically impossible for it to migrate the profiles automatically.
Unfortunately, some parts of the new Big Sur API may be unstable. There are issues that do not depend on Proxifier configuration or code. These issues have been reported to Apple, and we hope they will be resolved in future macOS updates. If you have any problems, please make sure that you are running the latest version of macOS.
Please feel free to contact us at firstname.lastname@example.org. We will do our best to help you.
To mitigate the problems, we have prepared a special build of Proxifier for Mac v2 that supports Big Sur using private API.
If you have problems with Proxifier for Mac v3, you can use this build.
