If accidentally press “Register…” button and delete KEXT (Kernel Extension) then:
- Install and uninstall downloads.ambrosiasw.com/snapzprox/essentials/SnapzProX2.3.3.dmg whilst leaving KEXT
  
  (forums.macrumors.com/threads/wiretap-pro-alternative-for-snow-leopard.1532877/)
- File, Record From: Mac Audio
```
(Otherwise get trial voice-over for Microphone/Line In)
```
Also be aware that WireTap Pro uninstaller leaves 'Music/WireTap Pro Recordings' (that may be used to check prior install)
Additional items:
```
$ brew install wget
```

1 - Eject stuck DVD¶ ↑

$ drutil tray eject;

2 - Create subdomains¶ ↑

Not so far…

3 - Grep only certain files¶ ↑

$ find . -name 'devise.rb'|xargs grep 'Devise.secret_key';

Much faster than:

$ grep -r 'Devise.secret_key' *;

$ grep -r –exclude='*.log' 'spree_bsc' *;

3b - Grep hidden files¶ ↑

$ grep -i path .*

4 - Toggle case in Vi¶ ↑

~ = Toggle case under cursor

5 - Package management systems¶ ↑

MacPorts - Based on FreeBSD Ports system [NOW, NOT INSTALLED ON MY SNOW LEOPARD REINSTALL]

Eschews Apple-supplied libs and links against its own to ensure consistency Uses 'subversion' as its code manager
Fink - Based on Debian's dpkg and apt-get [NOT INSTALLED ON MY SNOW LEOPARD]
Homebrew - Overcome MacPorts perceived downfalls

Written in Ruby + works with OSX's existing frameworks/libs Uses 'git' as its code manager

Formula: /usr/local/Library/Formula Downloads: /Library/Caches/Homebrew

$ brew install –cc=gcc-5 poco

6 - Nested backticks¶ ↑

Use $(command) rather than `command`

eg:

$ pushd $(dirname $(which rails));

(15/5/16)

Make directory read-write by all

$ chmod -R 777 src

$ chmod -R 755 Documents
Disable Journalling

Disk utility-Select partition-Alt+File menu-Disable Journaling
Reboot into linux
Reenable Journalling when reboot OSX
Make linux files accessible from osx

$ sudo chmod -R 777 src

8 - Booting MacBook 5.1 into 64-bit mode¶ ↑

(21/5/16)

Check whether EFI can boot 64-bit kernel:

$ ioreg -l -p IODeviceTree | grep firmware-abi
  | |   "firmware-abi" = <"EFI64">

Only MacBook “Pro” supports ability to boot 64-bit kernel with 64-bit EFI
