🎛 System Performance Boosters

1. Reduce WindowServer Lag (Smoother Animations & Faster UI)

The WindowServer process handles macOS graphics, and too many UI effects slow it down.
Fix it by disabling unnecessary effects:

• Turn Off Transparency Effects (Big FPS Boost for UI) arduinoCopyEditdefaults write com.apple.universalaccess reduceTransparency -bool true
  • Speeds up Mission Control, Dock animations, and window movements.
• Reduce Window Animations for Snappier UI arduinoCopyEditdefaults write -g NSAutomaticWindowAnimationsEnabled -bool false
  • Windows open instantly instead of animating.
• Speed Up Dock Animation (Makes Apps Open Faster) arduinoCopyEditdefaults write com.apple.dock autohide-time-modifier -float 0.1 defaults write com.apple.dock autohide-delay -float 0 killall Dock
  • Removes Dock delay and makes it appear instantly.

2. Unlock Pro-Level CPU & GPU Performance

A. Disable macOS CPU Throttling for Maximum Speed

css
sudo pmset -a dps 0

• Prevents macOS from underclocking the CPU, useful for gaming & video editing.

B. Force Mac to Use High-Performance GPU (For Dual-GPU Macs)

css
sudo pmset -a gpuswitch 0

• Ensures macOS always uses the dedicated GPU instead of the power-saving one.

C. Enable Turbo Boost Always On (Intel Macs)

nginx
sudo sysctl -w machdep.cpu.turbo_enabled=1

• Runs CPU at max power, useful for rendering & gaming.

---

3. Prevent macOS From Randomly Sleeping (Great for Downloads & Long Tasks)

bash
sudo pmset -a sleep 0

• Stops auto-sleeping during long downloads, rendering, or remote access.

4. Secret Finder Tweaks (Boost File Browsing & Navigation Speed)

A. Enable Hidden “Quit Finder” Option (Like Any App)

arduino
defaults write com.apple.finder QuitMenuItem -bool true
killall Finder

• Lets you fully quit Finder like a normal app.

B. Make Finder Show Hidden System Files

arduino
defaults write com.apple.finder AppleShowAllFiles YES
killall Finder

• Reveals system files Apple hides by default (be careful what you delete!).

C. Change Default Screenshot Format (PNG → JPG, PDF, etc.)

lua
defaults write com.apple.screencapture type jpg
killall SystemUIServer

• Changes screenshot format (JPG is smaller than PNG).
• Other formats: png, pdf, gif, tiff.

🎨 Hidden UI & Dock Customizations

5. Remove Useless MacBook Startup Sound

perl
sudo nvram SystemAudioVolume=%80

• Mutes Mac startup chime permanently.

6. Enable Hidden Dark Mode Terminal Theme

swift
osascript -e 'tell application "Terminal" to set current settings of window 1 to settings set "Pro"'

• Applies hidden Pro theme in Terminal.

7. Center Mac Dock (Looks Like Windows 11)

lua
defaults write com.apple.dock orientation -string bottom
defaults write com.apple.dock pinning -string middle
killall Dock

• Moves Dock icons to the center.

8. Hide Dock Completely (Only Appears When Needed)

arduino
defaults write com.apple.dock autohide -bool true
defaults write com.apple.dock showhidden -bool true
killall Dock

• Keeps Dock hidden until you move your mouse to the bottom.

🖥 Hidden Display & Scaling Tricks

9. Enable HiDPI Mode for Non-Retina Displays (Makes Text Look Sharper)

arduino
sudo defaults write /Library/Preferences/com.apple.windowserver DisplayResolutionEnabled -bool true

• Improves text sharpness on external monitors.

10. Set Any Custom Resolution for External Monitors

• App Needed: BetterDisplay
• Lets you unlock hidden resolutions and enable HiDPI mode.

11. Reduce External Display Input Lag (For Gaming)

arduino
defaults write com.apple.CoreGraphics DisableVSYNC -bool true

• Disables V-Sync, reducing input delay on external monitors (may cause tearing).

---

🚀 Hidden Safari & Browser Speed Boosts

12. Enable Safari’s Secret Developer Features

arduino
defaults write com.apple.Safari IncludeInternalDebugMenu -bool true

• Unlocks hidden Developer Debug Menu in Safari.

13. Remove Delays in Safari for Faster Browsing

arduino
defaults write com.apple.Safari WebKitInitialTimedLayoutDelay 0.25

• Reduces rendering delays, making Safari load pages faster.

---

🔋 Hidden Battery & Power Tweaks

14. Check Battery Health & Cycle Count

perl
system_profiler SPPowerDataType | grep "Cycle Count"

• If the count is over 1000, your battery may need replacing.

15. Limit Maximum Charge to 80% (Extends Battery Lifespan)

• Use AlDente (Download Here)
• Prevents overcharging, increasing battery life.

---

🎯 Hidden Productivity Tweaks

16. Automatically Lock Mac When You Step Away

arduino
defaults write com.apple.screensaver askForPassword -int 1
defaults write com.apple.screensaver askForPasswordDelay -int 0

• Locks instantly when the screensaver starts.

17. Prevent USB Devices From Waking Your Mac

css
sudo pmset -a hibernatemode 25

• Stops USB devices from randomly waking your Mac (great for MacBooks).

---

🔑 How to Undo These Tweaks?

If you ever want to reset any setting, just replace true with false, or use this:

pgsql
defaults delete com.apple.[name]
killall Finder/Dock/SystemUIServer

Example:

pgsql
defaults write com.apple.dock autohide-time-modifier -float 0
killall Dock

Restores Dock animation to default.
