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 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 ``` ### 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 ``` ### 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.
