# Preparing your System for HDD + SSD usage

This will disable Spotlight on your selected Drive and it will stop spinning after 1 minute (for this the option must be first activated in energy preferences). Useful for Macs with HDD and SSD.

```

# mdutil -d /Volumes/diskX

# mdutil -i off /Volumes/diskX

# pmset -a disksleep 1

```



# Testing your Memory

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

## with normal RAM usage

1. Download Memtest and install

2. type *memtest all 2* this will test your whole unused memory 2 times



## with minimal RAM usage (recommend)

1. Download Memtest and install

2. restart your Mac and hold down cmd+s while starting

3. 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://` 



### 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

```



to



```

/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

# Editing Apple-Apps



## Enable diskutility debug-menu



    $ defaults write com.apple.DiskUtility DUDebugMenuEnabled 1

    # 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

1. Edit the info.plist located in: */Applications/Utilities/Boot Camp Assistant.app/Contents*.

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*

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.
