Mail

Vacuum Mail Index

The AppleScript code below will quit Mail, vacuum the SQLite index, then re-open Mail. On a large email database that hasn't been optimized for a while, this can provide significant improvements in responsiveness and speed.

(*
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'}"

display dialog ("Mail index before: " & sizeBefore & return & "Mail index after: " & sizeAfter & return & return & "Enjoy the new speed!")

tell application "Mail" to activate

Vim

Compile Sane Vim

Compiling MacVim via Homebrew with all bells and whistles, including overriding system Vim.

brew install macvim --HEAD --with-cscope --with-lua --with-override-system-vim --with-luajit --with-python

Neovim

Install the development version of this modern Vim drop-in alternative via Homebrew.

brew tap neovim/neovim && \
brew install --HEAD neovim

Xcode

Install Command Line Tools without Xcode

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.

sudo pmset -a sms 0

Eject All Mountable Volumes

The only reliable way to do this is by sending an AppleScript command to Finder.

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.

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)

Set Boot Volume

bless --mount "/path/to/mounted/volume" --setBoot

Show All Attached Disks and Partitions

diskutil list

View File System Usage

A continuous stream of file system access info.

sudo fs_usage

Disk Images

Create Disk Image From Folder Contents

hdiutil create -volname "Volume Name" -srcfolder /path/to/folder -ov diskimage.dmg

If you'd like to encrypt the disk image:

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:

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.

hdiutil burn /path/to/image_file

Disable Disk Image Verification

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

bless --folder "/path/to/mounted/volume/System/Library/CoreServices" --bootinfo --bootefi

Mount Disk Image

hdiutil attach /path/to/diskimage.dmg

Unmount Disk Image

hdiutil detach /dev/disk2s1

Write Disk Image to Volume

Like the Disk Utility "Restore" function.

sudo asr -restore -noverify -source /path/to/diskimage.dmg -target /Volumes/VolumeToRestoreTo
