This will always bring up the extended save dialog in all applications.

$ defaults write -g NSNavPanelExpandedStateForSaveMode -bool TRUE

You need to restart your machine afterwards.

This will always bring up the extended print dialog in all applications.

$ defaults write -g PMPrintingExpandedStateForPrint -bool TRUE

You need to restart your machine afterwards.

enable Night Shift on older machines.

# cd /System/Library/PrivateFrameworks/CoreBrightness.framework/Versions/Current
# nm CoreBrightness |grep _ModelMinVersion
000000000001e260 S _ModelMinVersion

0x1e260 is the starting position add 4 to the offset to access all machine types. offset 0 is MacBookPro, followed by iMac, Macmini, MacBookAir, MacPro and MacBook. We use node to rewrite the CoreBrightness binary for the MacBook Pro (offset 0).

# node
> const a = fs.readFileSync('CoreBrightness');
> a[0x1e260]
9
> a[0x1e260] = 8;
> fs.writeFileSync('CoreBrightness', a);
> .exit

Now we resign the binary:

# codesign -f -s - /System/Library/PrivateFrameworks/CoreBrightness.framework/Versions/Current/CoreBrightness

Don't forget to reboot your machine.

generally use cifs:// instead of smb:// https://discussions.apple.com/thread/6635652?start=0&tstart=0

This will speedup smb (samba) connections. Write a file (as root) with:

[default]
minauth=none
streams=no
soft=yes
notify_off=yes
port445=no_netbios

to

/private/etc/nsmb.conf

tested for 10.9

• (src|dst) means src-port xor dst-port
• replace {port} with the port number you want to throttle

# ipfw pipe 1 config bw 500KByte/s
# ipfw add 1 pipe 1 (src|dst)-port {port}
# ipfw delete 1

tested for 10.8 - 10.9

As soon as you edit any .plist etc. in an original Apple-App it crashes after editing the .plist, because every App is signed by Apple. To sign the edited App (e.g Boot Camp Assistant) get root and type:

# codesign -fs - /Applications/Utilities/Boot\ Camp\ Assistant.app

only necessary for 10.9

Source: https://www.youtube.com/watch?v=5A5FG8EMEGc

1. Edit the info.plist located in: /Applications/Utilities/Boot Camp Assistant.app/Contents.
2. Search for the string PreESDRequiredModels and paste your Model Identifier e.g. MacBookPro7,2 (You can find the Identifier in Mactracker or by left clicking the -Menu while holding down the "alt" Key and clicking "Systeminformation")
3. Copy your Boot-Rom-Version form the System-Profiler, which you start by left clicking the -Menu while holding down the "alt" Key and clicking "Systeminformation" and paste it in the info.plist at DARequiredROMVersions
4. To make your Mac boot from USB just delete the "Pre" from PreUSBBootSupportedModels and add your Model Identifier
5. Codesign your BootCamp Assistant

This disables the swoosh animation when you start Mission Control.

Changes the kelvin-temperature of your display when the sun goes down.

Ever notice how people texting at night have that eerie blue glow?

Or wake up ready to write down the Next Great Idea, and get blinded by your computer screen?

During the day, computer screens look good—they're designed to look like the sun. But, at 9PM, 10PM, or 3AM, you probably shouldn't be looking at the sun.

f.lux fixes this: it makes the color of your computer's display adapt to the time of day, warm at night and like sunlight during the day.

It's even possible that you're staying up too late because of your computer. You could use f.lux because it makes you sleep better, or you could just use it just because it makes your computer look better.
