Guides on emulating older applications

A very famous (or infamous, due to all the stability issues it caused later in its life) tool used for hacking applications. Its aim was to bring the classic Mac OS's modularity to OS X. It can essentially be seen as the proprietary competitor to SimBL (Web Archive).

First download is Version 2.6.1 released Sep 2, 2010 for Leopard and Snow Leopard (10.5 & 10.6), second is for Tiger (10.4), third is for Panther (10.3), fourth is for Jaguar (10.2) and last one is for Puma (10.1).

See Also: FruitMenu, ShapeShifter - examples of software that uses Application Enhancer (APE) technology.

Final Web Archive captures of Unsanity's Application Enhancer downloads and documentation.

Further reading: What happened to Unsanity? and Application Enhancer (Wikipedia).

Architecture: PPC x86 (Intel:Mac)

Requires Rosetta for Intel Mac's as parts of the program are still PowerPC code.

The link to SimBL in the description seems to be broken

Now a Web Archive link

The link to SimBL in the description seems to be broken. "Server not found" error. I'd like to request confirmation... If the link is indeed broken, obviously it'll need to be fixed or removed, but I've had such issues before that have turned out to simply be problems with my internet connection.

The SDK for version 2.6.1 (latest version, compatible with 10.5 Leopard) is available via, but I couldn't find the one for version 2.5.2 (latest 10.4 Tiger version) anywhere.

If anyone ever happens to come across "apesdk-252.dmg", please kindly upload it here, if possible.
