Testing your Memory

Source: http://rampagedev.wordpress.com/os-x-tweaks/run-memtest-under-mac-os-x/

with normal RAM usage

Download Memtest and install
type memtest all 2 this will test your whole unused memory 2 times

with minimal RAM usage (recommend)

Download Memtest and install
restart your Mac and hold down cmd+s while starting
Type memtest all 6 into prompt. To save the results into .txt file you need to mount your volume with # /sbin/mount -uw / and then run memtest all 6 > output.txt this will save all results to the root of the volume.

Display

Source: https://pikeralpha.wordpress.com/2017/01/30/4398/

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.

Networking

SMB / CIFS (samba)

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

speedup connection

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

/private/etc/nsmb.conf

tested for 10.9

throttle TCP/IP Port throughput

(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

disable delayed tcp ack

Source: http://www.jeremycole.com/blog/2010/01/13/delayed-ack-in-os-x-is-incomprehensible/

# echo 'sysctl -w net.inet.tcp.delayed_ack=0' >> /etc/sysctl.conf

keep bluetooth disable on startup

Source: http://www.kernelcrash.com/blog/os-x-disabling-bluetooth/2007/11/12/

# defaults write /Library/Preferences/com.apple.Bluetooth “ControllerPowerState” -bool FALSE

Editing Apple-Apps

Enable diskutility debug-menu

$ defaults write com.apple.DiskUtility DUDebugMenuEnabled 1

codesign

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

Make BootCamp Assistant create a bootable USB-drive on Mac's with optical drive

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

Edit the info.plist located in: /Applications/Utilities/Boot Camp Assistant.app/Contents.
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")
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
To make your Mac boot from USB just delete the "Pre" from PreUSBBootSupportedModels and add your Model Identifier

flux

http://justgetflux.com/

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.
