Setting Up a Mac

👋 Thanks for reading! Things have changed since this was written, take it with a grain of salt ;)

Time Machine

To add a size limit to time machine backups. Backup size should be around 1.5x the hard drive size… so 500gb > 750gb > 750 x 1024 = 768000

sudo defaults write /Library/Preferences/ MaxSize 102400

Sublime Text

Useful packages

  • Virtualenv
  • HTMLBeautify
  • SideBarEnhancements
  • ZPL Format


useful packages

  • tree - used in terminal to pretty print directory contents.
tree -v --charset utf-8 -I venv
  • python3
brew install python3

If you upgrade python the links in virtualenv’s will break. They can be deleted and recreated.

If you are in a directory with a virtual envirenment called venv this should work:

# find broken links
find venv/ -type l
# delete broken links
find venv/ -type l -delete
# create new links
virtualenv venv


Nice color scheme -

Safari DNS


Somehow the home and end buttons on the apple keyboard don’t go to the right place :)

This will fix it -

# create/edit the key bindings file
cd ~/Library
mkdir KeyBindings
sudo nano ~/Library/KeyBindings/DefaultKeyBinding.Dict

# paste in and save. You will need to restart your mac
    "\UF729"  = moveToBeginningOfParagraph:; // home
    "\UF72B"  = moveToEndOfParagraph:; // end
    "$\UF729" = moveToBeginningOfParagraphAndModifySelection:; // shift-home
    "$\UF72B" = moveToEndOfParagraphAndModifySelection:; // shift-end
    "^\UF729" = moveToBeginningOfDocument:; // ctrl-home
    "^\UF72B" = moveToEndOfDocument:; // ctrl-end
    "^$\UF729" = moveToBeginningOfDocumentAndModifySelection:; // ctrl-shift-home
    "^$\UF72B" = moveToEndOfDocumentAndModifySelection:; // ctrl-shift-end
    "$\U007F" = deleteWordBackward:;

Using Oracle EBS

Install Firefox

Firefox 52 is the last version working with Oracle EBS Forms. Download it here.

Install Java

The latest version of java is currently working well. You can download here.

Change settings in Java Control Panel

EBS Forms needs to be allowed as a safe site in Java.

  1. On the mac open System Preferences > Java.
  2. In Java Control Panel Security Tab > Edit Site List.
  3. Add in the root of your ebs system. Example:

First Use

On the first use when logging in in Firefox click “activate java” when prompted, and then allow popups when prompted.

Terminal Alias

If you are typing the same phrase in terminal over and over and over it may be handy to create an alias name…

# edit bash profile
nano ~/.bash_profile

# for catelena and newer
nano ~/.zprofile

# add in the alias

# Aliases - remember no spaces at equals sign
alias act="source venv/bin/activate"
alias dact="deactivate"
alias ip="ifconfig | grep 'inet '"
alias gc="git add . && git commit -m "
# save
# restart terminal or reload
source ~/.bash_profile

UTF-8 Error when running python 3scripts from terminal, or through venv in Sublime

Edit your bash profiel to include these two lines -

# edit file
nano ~/.bash_profile

# add these lines and save.
export LC_ALL=en_US.UTF-8
export LANG=en_US.UTF-8
