Краткие советы для Macbook Air

Written by  Monday, 28 October 2013 02:00

В целях экономии ресурсов системы OSx, можно снизить на 10% потребление электроэнергии. По умолчанию Spotlight потребляет около 14% (взято из моего Activity Monitor - AVG Energy Impact). После выполнения этой команды в Терминале, мы отключим индексацию поиска в Mac и получим снижение потребления до 0%.

sudo mdutil -a -i off
чтобы вернуть индексацию нужно выполнить команду
sudo mdutil -a -i on

 Естественно проделывать этот трюк нужно тем, кто активно не использует поиск в своем Macbook Air. Я его вообще не использую и пользуюсь TotalCommander.

Второе — отключить создание локальной резервной копии. Она занимает лишние несколько гигабайт, а когда у вас всего 128 ГБ, то каждый из них — на вес золота. Сделать это можно при помощи данной команды:

sudo tmutil disablelocal

  • Launch Sublime Text 3 from the command line & simlink to Subl
    in Mac

    These instructions assume you’re using the Terminal app out of the box, without ZSH or any fancy prompts like that. I trust you will be able to adapt these instructions yourself if you do.

    Step 1 : Create a symlink called sublime

    sudo ln -s "/Applications/Sublime Text.app/Contents/SharedSupport/bin/subl" /usr/local/bin/sublime

    Step 2 : Check that your system profile can find the symlink you just created.

    open ~/.bash_profile

    Step 3 : Add both these lines & then save the file :

    alias subl="open -a /Applications/Sublime\ Text.app"
    export PATH=/usr/local/bin:$PATH

    Step 4 : Reload your bash_profile :

    source ~/.bash_profile

    Done ! You can now navigate to any of your code/script folders in Terminal and open them in Sublime with the following commands :

    subl .
    subl .zshrc

  • Customize OS X's Login Screen with Any Logo You Want
    in Mac

    The login screen on your Mac is perfectly functional as it is, but if you want to spice it up a little bit, blogger Jacob Salmela shows you how to customize the login screen with a logo of your choosing.

    If you don't want to install a whole program just for a simple tweak it's easy to do manually. All you need is a PNG that's 428 X 248. Then, you'll need to save it as four different files.

    Here's instructions:

    You need four copies of this file, and they need to be named:

    • apple.png
    • apple@2x.png
    • apple_s1.png
    • apple_s1@2x.png

    Once they are named correctly, just drag them into the following path:


    and then choose to replace all of them.

    That's it, log out, and you should see your new logo. Head over to Salmela's site for a few sample images and instructions for making your own.
