Emulation
Guides on emulating older applications

TCPBlock is a lightweight and fast application firewall for OS X or later developed by Jo Delantis. The OS X firewall protects you from connections that come from outside of your computer. But what about the software from your computer that opens new connections to the internet? With TCPBlock you can prevent selected applications on your computer from opening connections to the network.

TCPBlock is implemented as a loadable kernel module which contains all the blocking logic. You can configure it in the System Preferences TCPBlock preference pane or with the tcpblock command line utility. All the configuration changes are made persistent in a configuration file on the hard disk. At system boot time the TCPBlock kernel extension reads its configuration from disk and is ready to go.

By October 2014, TCPBlock was offered for sale to the public — the web site vanished shortly after and TCPBlock was discontinued.

Compatibility
Architecture: PPC x86 (Intel:Mac)

TCPBlock v2.10 requires 10.5 Leopard (PPC/Intel). TCPBlock v4.2 requires 10.6 Snow Leopard (Intel only) and later.

Note: TCPBlock is not compatible with OS X 10.10 Yosemite or newer.

We're still looking for TCPBlock v3.0, an intermediate release between v2.10 & v4. If you have it, please upload it to this page.
