This app works with: SheepShaver,

Carbon is the name for Apple's "API" which bridges Mac OS 8/9 and Mac OS X so that a class of individual "carbonized" program files can be run from both OS's (8/9+X) that are incredibly different from each other. Quoting Apple: "CarbonLib allows Apple's developers to write an application with one set of sources deployed across Mac OS 8, Mac OS 9 and Mac OS X systems with minimal effort." In a loose sense Carbon can be thought of as Apple's OS X emulator for on 8/9, opposite of Apple's Classic emulator for on X. Ultimately the familiar more-modern OS-X-only "API" got another name, Cocoa.

CarbonLib is required when running carbonized software in the classic Mac OS versions 8.1 to 9.2.2, not required for Mac OS X because carbonized applications are Mac OS X native. CarbonLib consists of one classic Extensions file, of which a version began being supplied with the OS at about Mac OS 9.0.0 and CarbonLib can be updated or otherwise installed into system versions older than 9.0 down to Mac OS 8.1 - CarbonLib v1.6.1 (year 2003) is its highest version. v1.0.0 is located on the install cd for OS 9.0.0 and, also not on our page, v1.1.1 can be found in the OS 9.1 Update tome.

Most of these downloads are English-only (unless otherwise stated) self mounting images of installers which inject only a single file "CarbonLib" in "System Folder/Extensions/". TomeViewer can be used to Extract and manipulate the file manually, without running installers. v1.0.4 has more than one file, a readme, plus a "Navigation Services" file meant for OS 8.1-only.

First download is version 1.0.4
Second download is version 1.2
Third download is version 1.2.5
Fourth download is version 1.3.1
Fifth download is version 1.4
Sixth download is version 1.5
Seventh download is v1.6 in All 15 languages
Eighth download is version 1.6 in English
Ninth download is the CarbonLib 1.6 SDK (programmers tool)
Tenth download is v1.6.1 in All 15 languages
Eleventh download is version 1.6.1 English

2003-09 ... v1.6.1 was distributed
2002-06 ... v1.6.0
2001-12 ... v1.5

1999-09 ... v1.0.0

Architecture: PPC

Mac OS 8.1 - Mac OS 9.2.2
Mac OS 8.6 required minimum for CarbonLib v1.6 & 1.6.1
v1.6.1 is the highest and the only version never offered by Apple as a downloadable self mounting image,
it showed up originally only after installing from certain models' OS discs.

Steve Jobs said they named the library Carbon because "all [Mac Software] life will be based on it".

Apple pushed Carbon apps very heavily because it meant classic apps could get ported to Mac OS X very quickly, and it meant that the people who did not want to run Mac OS X (which was the majority of Mac owners, OS X was a mess for many releases) could get apps that would work on classic.

There were very few developers interested in making Cocoa apps for many years. It was mainly shareware apps that used Cocoa for the longest time. Quark flat out refused to bring Xpress to Mac OS X because they thought it would fail, and they didn't believe Carbon had enough of the class Mac APIs in it.

I'm pretty sure 1.0.4 was the last version that ran on 8.1.

Does anyone know what was the highest version of CarbonLib that Mac OS 8.1 could take? v1.5?

ok the readme supplied with carbon 1.0.4 says it runs on OS 8.1

I've not seen it said anywhere else, I think Apple selected the name "Carbon" for this coming from "been frozen in Carbonite" in the movie Star Wars The Empire Strikes Back. Carbon's development state had to be 'frozen', that's how it would remain compatible for the next decade. Carbonized is a funny word too. They could've said "carbonated" ...but 'carbonized' invokes the Star Wars visual, moreso than if to say Han Solo was 'carbonated' at the end of the movie.

Um I found this page with os 8.6 described minimum but 8.1 mentioned (twice) for compatibility. It is 8.6 min not 8.1 rite?

I think it depends on the version of CarbonLib. The newer the higher the Mac OS requirement.

I finally found the long lost v1.5 and up'd it here (as typical my effort here could become 'reordered' by somebody who can).
I get fastest performance from 1.4 & 1.5 and many programs thought to have required v1.6 do run (fast) with v1.5
v1.6 runs slow for me and v1.6.1 highest is weird, 1.6.1 looked equally as slow as 1.6.0 when my model ID was PowerMac3,6 (G4) but now that I've upgraded my hw model to PowerMac7,2 (G5, yes I run OS9 on a G5) CarbonLib v1.6.1 appears as good as v1.5 and v1.6 still sucks.

Um I found this page with os 8.6 described minimum but 8.1 mentioned (twice) for compatibility. It is 8.6 min not 8.1 rite?

Tried again to install the version archived here, but now detected that's a different language version that won't install on my non-English SheepShaver installment. Here is the Apple Download page:

If we archive all language versions here?

I've installed this version in Sheep/Mac OS 9 yet. The original CarbonLib version was 1.0.1 there.

"... including Classic" sounds true, in case you tick 'Run in Classic Environment' in the Information window of the application (available in Mac OS X only) .

Updated description with your comment. Thanks.

This is required to run carbonized applications in the classic Mac OS versions mentioned, 8.6 to 9.2.2, not required for Mac OS X, because carbonized applications are Mac OS X native.
Thanks for archiving here.
