It is recommended that you completely backup any system that this theme will be installed on. It is NOT recommended that this theme be installed on a production system.

...and please, don't mess with the install and uninstall scripts unless you know what you're doing!

SYSTEM REQUIREMENTS:

A PowerPC Macintosh running a fully-updated installation of Mac OS X 10.4.11. This will NOT work on an Intel machine, or on any other version of Mac OS X. As this release doesn't modify any extra applications (iTunes, etc.), there is no need to be completely up-to-date with those applications, or with Java. The effects of installing this theme on a system below these requirements is unknown, and is done at YOUR OWN RISK.

INSTALLATION:

0. CLOSE ALL APPLICATIONS!

1. Double-click "Install". Enter your user password (if required) and hit Return. Follow the prompts.

2. You will have a choice of whether to replace your Lucida Grande font with the San Francisco font. You will lose use of the original Lucida Grande font if you choose to install San Francisco, but the theme will look a bit more accurate with it installed.

3. DO NOT OPEN ANY APPS, POWER DOWN THE SYSTEM, CLOSE THE TERMINAL WINDOW, OR OTHERWISE INTERRUPT THE INSTALLATION PROCESS!!!

4. Once the resources are installed, the system will perform a permissions repair. Let it finish.

5. Your system will reboot automatically once the installation is complete.

6. Enjoy your Sierra-themed Tiger installation!

UNINSTALLATION:

0. CLOSE ALL APPLICATIONS!

1. Double-click "Uninstall". Enter your user password (if required) and hit Return. Follow the prompts.

2. DO NOT OPEN ANY APPS, POWER DOWN THE SYSTEM, CLOSE THE TERMINAL WINDOW, OR OTHERWISE INTERRUPT THE RESTORATION PROCESS!!!

3. Your system will perform a permissions repair, then reboot automatically upon completion of the restoration.

4. Enjoy the splendor of Aqua once again!

INSTALLING ICONS:

There are two iContainer packages included in this theme package that you can load into CandyBar that will change many of your System and Applications icons. As these packages do not contain every application icon known to man, there are manual ways to change the icons. Members of the PowerPC forums at macrumors.com (linked at the top of this document) can help with this.

OTHER RESOURCES:

There are a number of applications that you can install that approximate later macOS functionality. Here is a short list:

RapidOStart- Launchpad
MacGizmo- Quicklook
xPad- Notes
ImagineBootX- change boot screen
ClearDock- change Dock color/transparancy
MenuShade- add transparancy to the menu bar
PPCAppStore- an app store for PowerPC!

These apps can be easily found by searching for them. A few sites to check out are:

PowerPC Archive- http://ppcarchive.dyniform.net/software.html
Mac PowerPC- https://macpowerpc.com/

TROUBLESHOOTING:

If you see the error "rm: /Users/<your user name>/Library/Caches/com.apple.preferencepanes.cache: No such file or directory", it is completely normal and nothing to worry about.
