Disclaimer

Please exercise caution not to flip any switches that are already active, and under no circumstances interrupt any scripts while they are still running. Both actions carry the potential to inflict varying levels of damage to the operating system. If the system becomes inadvertently damaged as a result of one or more of these actions, you must back up your files and reinstall the OS.

Updates

14. Unlockupd

Run sudo /usr/local/bin/unlockupd_remove to uninstall.

15. Finishing Touches (1. Add Quality of Life Improvements)

Upgrades Weather.wdgt to revised version, installs TwitterColorEmoji font, Shuriken App Store, Think, Aqua Dark desktop pictures, third-party screen savers, Safari performance optimizations, Invidious configurations, about command, activates visual indicators for hidden items within the Dock, and repairs disk permissions.

15. Finishing Touches (2. Enable QuickTime Pro)

More resource-heavy than QuickTime Basic; not recommended for G3 or G4-based Macs.

Optimizations

1. Quartz Compositor (Disable Beam Sync)

Disables Apple's custom V-Sync implementation, increasing the FPS of all 2D graphics.

1. Quartz Compositor, PCI Graphics (Enable Quartz Extreme on PCI Video Cards)

Forcibly hardware accelerates the Quartz Compositor for increased 2D graphics performance. Requires an ATi Radeon or nVIDIA GeForce2 MX GPU or better. This tool is not necessary for Macs using an AGP or PCIe graphics bus.

2. Spotlight (Disable Spotlight)

Disables Spotlight, removing both the menu bar icon and multiple background services, freeing up large amounts of hardware resources, and as a result significantly increasing the performance of all other processes in the system. Also disables the ability to search for files and folders from Finder windows.

3. Network (Enable Network Optimizations)

Configures Darwin to more efficiently transfer large amounts of data throughout LAN and WAN (Internet) environments, drastically increasing upload and download throughput rates.

4. NFS (Disable NFS Interfacing)

Disables multiple background services required to facilitate transfer to network shares using the NFS file sharing protocol. Has no effect on network shares using the FTP, SFTP, SMB, and AFP alternate file sharing protocols.

5. Universal Ad Blocking (Enable Universal Ad Blocking)

Activates system-wide protection against libraries of ad, tracking, fingerprinting, and datamining servers. Affects all browsers regardless of installed extensions.

6. Universal Access (Disable Universal Access Background Monitor)

Disables the Universal Access background service, responsible for on-demand text-to-speech services, all-display zoom functionality, and other Universal Access-related integrations.

7. Bonjour (Disable Bonjour)

Disables the Bonjour background service, responsible for both automatically finding other computers on the network, as well as automatically displaying the current computer to other systems with Bonjour / Rendezvous / ZeroConf support.

8. iOS Devices (Disable iOS Device Communication)

Disables a background daemon responsible for facilitating the transfer of data between Mac OS X and iOS-based peripherals. Clickwheel-based iPods are unaffected by this preference. Only applicable for iTunes 8 and later (version 7 untested).

9. Streamlining (1. Remove Junk Plug-Ins)

Removes the pre-installed Adobe Flash Player, Macromedia Shockwave, and VerifiedDownloadPlugin Safari plug-ins.

9. Streamlining (2. Remove Junk Assets)

Removes iTunes Helper, additional Macromedia-related files, modem scripts, and the deprecated .Mac preference pane.

9. Streamlining (3. Remove Junk Extensions)

Removes AudioIPCDriver, internal modem support, USB modem support, and clears kernel extension cache.

Tools

Appearance (Pinstripes)

Replaces all appearances of brushed metal throughout the system with the white pinstripes-themed menu bar and window style prevalent in Mac OS X 10.2 and below. Do not mix and match with the Platinum or Sierra themes.

Appearance (Platinum)

Hides the Dock, installs X-Assist to better mimic Mac OS 9 app switching, replaces default desktop pictures with Mac OS 9 desktop pictures, and replaces most system icons to combination Mac OS 9 and NeXTSTEP equivalents, creating a Mac OS X Server-inspired look and feel. Do not mix and match with the Pinstripes or Sierra themes.

Appearance (Sierra)

Installs macOS Sierra desktop pictures, user pictures, and system assets on top of the original Tiger equivalents. Run CandyBar afterwards (located in the Icon Theme folder) to install the accompanying Applications and System icon files (File > Open iContainer...). Do not mix and match with the Pinstripes or Platinum themes.

Demos (Core Image Fun House)

All-in-one demo application to apply various filters, distortions, and other impressive graphics effects to a selected image by leveraging Core Image technology - the same graphical framework responsible for hardware accelerated effects such as the ripples in Dashboard (an OpenGL 2.0 GPU is recommended).

Demos (Atlantis)

OpenGL demo of whales and sharks swimming in circles.

Demos (Ideas)

OpenGL demo of dynamic shadow updating and local lighting, featuring the famous Silicon Graphics tagline "Ideas In Motion".

Demos (Logo)

OpenGL demo of the OpenGL logo assembling itself in midair. Press Space to replay its reassembly.

Demos (Newave)

OpenGL demo of a morphing, fluctuating shape. Click and drag to rotate. Right-click for options.

Demos (Noof)

OpenGL demo of various shapes flying across the screen, leaving undulating trails as they pass.

Demos (Skynet)

Shell demo intended to be amusing. No changes are applied to the system while running.

Maintenance (1. — 6.)

Run FreeBSD daily / weekly / monthly periodic maintenance scripts, and clear the user / library / system caches. Scripts are recommended to be run approximately once a month for optimal system performance.

Memory (Disable Safe Sleep)

Prevent the system from copying RAM contents to disk before entering sleep mode. This decreases the time required to sleep, but increases the chances of data loss in the event of an unexpected shutdown during sleep. In order to re-enable safe sleep, go to System Preferences > Energy Saver, and make any modification there.

Memory (Release Inactive Memory)

Repairs the disk permissions. This also releases the majority of inactive memory currently locked by the system, making this a particularly useful tool for quickly reclaiming consumed resources after uploading / downloading large amounts of data without ever having to reboot the machine.

Quartz Compositor (Restart Display Server)

Restarts the Quartz display server / window manager. Useful for clearing filled VRAM banks, thus reclaiming additional graphical performance without ever having to reboot the machine.

Quartz Compositor (Toggle Window Shadows)

Removes cosmetic shadows from the edges of application windows, pop up windows, and drop down menus, increasing 2D graphics performance on weaker video cards. Can be automatically run at login by using System Preferences > Accounts > Login Items.

RAM Disks (1. — 9.)

Generates 64 MB to 1.75 GB RAM disks for temporary use with frequently-accessed files, increasing I/O performance at the cost of increased memory consumption, depending on the disk size chosen. In order to maintain optimal application performance, it is therefore recommended to leave at least 512 MB available for use by the system and its applications.
