```applescript
(*
Speed up Mail.app by vacuuming the Envelope Index
Code from: http://www.hawkwings.net/2007/03/03/scripts-to-automate-the-mailapp-envelope-speed-trick/
Originally by "pmbuko" with modifications by Romulo
Updated by Brett Terpstra 2012
Updated by Mathias Törnblom 2015 to support V3 in El Capitan and still keep backwards compability
*)
tell application "Mail" to quit
set os_version to do shell script "sw_vers -productVersion"
set mail_version to "V2"
considering numeric strings
if "10.10" <= os_version then set mail_version to "V3"
end considering
set sizeBefore to do shell script "ls -lnah ~/Library/Mail/" & mail_version & "/MailData | grep -E 'Envelope Index$' | awk {'print $5'}"
do shell script "/usr/bin/sqlite3 ~/Library/Mail/" & mail_version & "/MailData/Envelope\\ Index vacuum"
set sizeAfter to do shell script "ls -lnah ~/Library/Mail/" & mail_version & "/MailData | grep -E 'Envelope Index$' | awk {'print $5'}"

if [[ -z "$@" ]]; then
echo "Input file missing"
else
filename=${1%.*}
mkdir $filename.iconset
sips -z 16 16 $1 --out $filename.iconset/icon_16x16.png

```bash
xcode-select --install
```
#### Remove All Unavailable Simulators

xcrun simctl delete unavailable
```
## Disks and Volumes
#### Disable Sudden Motion Sensor
Leaving this turned on is useless when you're using SSDs.
```bash
sudo pmset -a sms 0
```
#### Eject All Mountable Volumes
The only reliable way to do this is by sending an AppleScript command to Finder.
```bash
osascript -e 'tell application "Finder" to eject (every disk whose ejectable is true)'
```
#### Repair File Permissions
You don't have to use the Disk Utility GUI for this.
```bash
sudo diskutil repairPermissions /
```
> Beginning with OS X El Capitan, system file permissions are automatically protected. It's no longer necessary to verify or repair permissions with Disk Utility. ([Source](https://support.apple.com/en-us/HT201560))
#### Set Boot Volume
```bash
bless --mount "/path/to/mounted/volume" --setBoot
```
#### Show All Attached Disks and Partitions
```bash
diskutil list
```
#### View File System Usage

```bash
sudo fs_usage
```

#### Create Disk Image From Folder Contents
```bash
hdiutil create -volname "Volume Name" -srcfolder /path/to/folder -ov diskimage.dmg
```
If you'd like to encrypt the disk image:
```bash
hdiutil create -encryption -stdinpass -volname "Volume Name" -srcfolder /path/to/folder -ov encrypted.dmg
```
By default, you'll be prompted for a password. You can automate that by piping in a password:
```bash
echo -n YourPassword | hdiutil create -encryption -stdinpass -volname "Volume Name" -srcfolder /path/to/folder -ov encrypted.dmg
```
#### Burn Disk Images to DVD
This command applies to .iso, .img and .dmg images.
```bash
hdiutil burn /path/to/image_file
```
#### Disable Disk Image Verification
```bash
defaults write com.apple.frameworks.diskimages skip-verify -bool true && \
defaults write com.apple.frameworks.diskimages skip-verify-locked -bool true && \
defaults write com.apple.frameworks.diskimages skip-verify-remote -bool true
```
#### Make Volume OS X Bootable
```bash
bless --folder "/path/to/mounted/volume/System/Library/CoreServices" --bootinfo --bootefi
```
#### Mount Disk Image
```bash
hdiutil attach /path/to/diskimage.dmg
```
#### Unmount Disk Image
```bash
hdiutil detach /dev/disk2s1
```
#### Write Disk Image to Volume
Like the Disk Utility "Restore" function.
```bash
sudo asr -restore -noverify -source /path/to/diskimage.dmg -target /Volumes/VolumeToRestoreTo
```
## Dock
#### Add a Stack with Recent Applications
```bash
defaults write com.apple.dock persistent-others -array-add '{ "tile-data" = { "list-type" = 1; }; "tile-type" = "recents-tile"; }' && \

```
#### Add a Space
```bash
defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="spacer-tile";}' &&\
killall Dock
```

The float number defines the show/hide delay in ms.
```bash
defaults write com.apple.Dock autohide-delay -float 0 &&\
killall Dock
```
#### Show Hidden App Icons
```bash

### LaunchServices

```
### Login Window
#### Set Login Window Text
```bash
sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText "Your text"
```
### Memory Management
#### Purge memory cache
```bash
sudo purge
```
#### Show Memory Statistics
```bash
# One time
vm_stat
# Table of data, repeat 10 times total, 1 second wait between each poll
vm_stat -c 10 1
```
### Notification Center
#### Disable Notification Center
```bash
launchctl unload -w /System/Library/LaunchAgents/com.apple.notificationcenterui.plist && \
killall -9 NotificationCenter
```

```

```bash
defaults write com.apple.SoftwareUpdate ScheduleFrequency -int 1
```

#### Set Software Update Server
This should only be done for testing purposes or unmanaged clients. To use network-wide, either correctly set up DNS along with [Apple SUS service](http://krypted.com/mac-security/using-the-software-update-service-on-mountain-lion-server/) and bind your clients via OpenDirectory. Alternatively, use [Reposado](https://github.com/wdas/reposado) together with correct network DNS settings to make resolution transparent. [Margarita](https://github.com/jessepeterson/margarita) looks nice to have as well.
```bash
# Use own SUS
sudo defaults write /Library/Preferences/com.apple.SoftwareUpdate CatalogURL http://su.example.com:8088/index.sucatalog
# Reset to Apple SUS
sudo defaults delete /Library/Preferences/com.apple.SoftwareUpdate CatalogURL
```
