On a large email database that hasn't been optimized for a while, this can provide significant improvements in responsiveness and speed. ```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 compatibility *) 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 ``` ### Safari #### Enable Develop Menu and Web Inspector ```bash defaults write com.apple.Safari IncludeInternalDebugMenu -bool true && \ defaults write com.apple.Safari IncludeDevelopMenu -bool true && \ defaults write com.apple.Safari WebKitDeveloperExtrasEnabledPreferenceKey -bool true && \ defaults write com.apple.Safari com.apple.Safari.ContentPageGroupIdentifier.WebKit2DeveloperExtrasEnabled -bool true && \ defaults write NSGlobalDomain WebKitDeveloperExtras -bool true ``` #### Get Current Page Data Other options: `get source`, `get text`. ```bash osascript -e 'tell application "Safari" to get URL of current tab of front window' ``` ### Sketch #### Export Compact SVGs ```bash defaults write com.bohemiancoding.sketch3 exportCompactSVG -bool yes ``` ### Skim #### Turn Off Auto Reload Dialog Removes the dialog and defaults to auto reload. ```bash defaults write -app Skim SKAutoReloadFileUpdate -boolean true ``` ### TextEdit #### Use Plain Text Mode as Default ```bash defaults write com.apple.TextEdit RichText -int 0 ``` ## Backup ### Time Machine #### Change Backup Interval This changes the interval to 30 minutes. The integer value is the time in seconds. ```bash sudo defaults write /System/Library/Launch Daemons/com.apple.backupd-auto StartInterval -int 1800 ``` #### Local Backups Whether Time Machine performs local backups while the Time Machine backup volume is not available. ```bash # Disable sudo tmutil disablelocal # Enable (Default) sudo tmutil enablelocal ``` #### Prevent Time Machine from Prompting to Use New Hard Drives as Backup Volume ```bash defaults write com.apple.TimeMachine DoNotOfferNewDisksForBackup -bool true ``` #### Set Status ```bash # Disable Local Time Machine Backups hash tmutil &> /dev/null && sudo tmutil disablelocal # Enable Local Time Machine Backups (Default) hash tmutil &> /dev/null && sudo tmutil enablelocal ``` ## Developer ### Vim #### Compile Sane Vim Compiling MacVim via Homebrew with all bells and whistles, including overriding system Vim. ```bash 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. ```bash brew tap neovim/neovim && \ brew install --HEAD neovim ``` ### Xcode #### Install Command Line Tools without Xcode ```bash xcode-select --install ``` #### Remove All Unavailable Simulators ```bash 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 A continuous stream of file system access info. ```bash sudo fs_usage ``` ### Disk Images #### 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"; }' && \ killall Dock ``` #### Add a Space ```bash defaults write com.apple.dock persistent-apps -array-add '{"tile-type"="spacer-tile";}' && \ killall Dock ``` #### Icon Bounce Global setting whether Dock icons should bounce when the respective application demands your attention. ```bash # Enable (Default) defaults write com.apple.dock no-bouncing -bool true && \ killall Dock # Disable defaults write com.apple.dock no-bouncing -bool false && \ killall Dock ``` #### Reset Dock ```bash defaults delete com.apple.dock && \ killall Dock ``` #### Scroll Gestures Use your touchpad or mouse scroll wheel to interact with Dock items. Allows you to use an upward scrolling gesture to open stacks. Using the same gesture on applications that are running invokes Exposé/Mission Control. ```bash # Enable defaults write com.apple.dock scroll-to-open -bool true && \ killall Dock # Disable (Default) defaults write com.apple.dock scroll-to-open -bool false && \ killall Dock ``` #### Set Auto Show/Hide Delay 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 # Enable defaults write com.apple.dock showhidden -bool true && \ killall Dock # Disable defaults write com.apple.dock showhidden -bool false && \ killall Dock ``` ##
