WebKit för Leopard och PowerPC

[Alix]

 

WebKit utvecklas (nu RC) för befintliga WebKit-beroende program i Leopard för PPC. Genom att installera WebKit får man de senaste funktionerna tillgängliga i exempelvis Safari 5.0.6. Man kan aktivera WebKit för valfria program genom det medföljande programmet Relink against Leopard WebKit (men se till att det stöds!). Med hela paketet följer också ett antal shellskript som bland annat uppdaterar systemcertifikat (lite oklart om det är Mavericks eller Yosemite), aktiverar avancerad grafik och avaktiverar Top Sites förhandsvisning (en självklarhet på en gammal PPC).

 

Länk här till WebKit (MacUpdate). För säkerhets skull skickade jag upp en kopia till min Google Drive här (som ni kan ladda ned om MacUpdates skulle försvinna).

 

Jag har testat på min iBook G4 och både Safari och Mail funkar fint (ja, nu funkar de alls...). Jag har dock inte testat avancerad grafik, det räcker iBooken ändå inte till för.

 

Readme-texten i spoiler:

 

The provided WebKit Application will launch the currently installed version of Safari, forcing it to use the updated WebKit frameworks provided by Leopard WebKit.

Leopard WebKit is tested with 5.0.6 (on 10.5) only.

Relink against Leopard WebKit:

This AppleScript droplet can be used to relink applications against Leopard Webkit, and it is the recommended way for using Leopard WebKit.

Just drop your favourite browser or other WebKit based application (like iTunes for example) on this droplet and it will create a copy of your application, appending "LepWK" to the original name (the name the application originally had when it was built).

The Leopard WebKit frameworks are then copied into the application bundle itself and relinked to refer each other in that location. That way each relinked application contains its own private copy of Leopard WebKit.

Be patient while the frameworks are copied and wait until the execution of the AppleScript finishes.

The relinking does only work for application that dont't load the WebKit frameworks at runtime, like Stainless for example.

It also doesn't yet work for many applications that contain frameworks or plugins inside the application bundle in locations different to what Apple recommends that are themselves linked against the Apple provided WebKit frameworks, like Safari for example.

It should work well with any applications that place frameworks in Contents/Frameworks and plugin bundles in Content/PlugIns, like Roccat 4.9 and later.

________________________

enable advanced features:

Enables all graphics acceleration features, HTML5 full screen support, WebGL and WebAudio

revert advanced features to defaults:

Resets the advanced features to the defaults built to the defaults of the currently installed version of WebKit.

________________________

disable TopSites preview rendering:

Disables the TopSites background web site preview image rendering which does free quite some precious system resources (CPU time, RAM, hard drive memory).

TopSites will not work as expected when preview image rendering is disabled as new sites won't get preview images and existing ones won't be updated any more.

revert disabling TopSites preview rendering:

Enables TopSites background web site preview rendering.

________________________

update system certificates:

This will bring the system security certificates up to date by overwriting the installed ones with the same files that Apple ships with 10.10 .

Please note that a backup will not be made. You can revert to the ones shipped with 10.5.8 by reinstalling the 10.5.8 update (http://support.apple.com/kb/DL865).

If you don't update, parts of certain web sites might not load and/or you'll get security warnings when visiting certain sites.

INSTALLING LEOPARD WEBKIT AS THE SYSTEM DEFAULT IS PURELY EXPERIMENTAL AND YOU SHOULDN'T DO IT IF YOU DON'T KNOW OF A WAY HOW TO RECOVER YOUR SYSTEM!!!

install:

Execute this to install Leopard WebKit as the system default.

Any application that was linked against the WebKit version provided by Apple will then use Leopard WebKit.

This affects Apple Mail, Dashboard, iCab, Stainless, Roccat and many more.

uninstall:

Execute this to delete Leopard WebKit and restore the Apple provided version to be the system default. You might also want to revert the advanced features settings to the defaults.
