MacBook 5.1¶ ↑

en.wikipedia.org/wiki/MacBook#Model_specifications_2

Release date: October 14, 2008 (ie 8 years old now!)

en.wikipedia.org/wiki/MacBook#Timeline_of_the_MacBook_family

Therefore the aluminium unibody MacBook had a very short shelf life before becoming MacBook Pro!

It's amazing that I didn't realise that before 23 Nov 2016
(but ringing bells about what I was told when bought in Oxford Apple store on Sat 2 May 2009), 

and the result of trying to upgrade to Xenial Xerus on 3 Nov 2016, 7.5 years (90 months) later... :)

Reinstall SnowLeopard¶ ↑

Install Git + Clone 'github.com/doughazell/spree-dynamic.git'

Download 'git-2.3.5-intel-universal-snow-leopard.dmg'

Install Homebrew:

Remove from '.profile'
```
export SSL_CERT_FILE
export SSL_CERT_FILE
export DYLD_LIBRARY_PATH
```
$ ruby -e “$(curl -fsSL raw.githubusercontent.com/Homebrew/install/master/install)”
RVM:

$ curl -sSL get.rvm.io | bash -s stable –rails
Qt:

$ brew install qt Needed for gem 'capybara-webkit'

Install Postgresql:

$ ln -sfv /usr/local/opt/postgresql/*.plist ~/Library/LaunchAgents
$ launchctl load ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist

$ initdb /usr/local/var/postgres -E utf8
  The files belonging to this database system will be owned by user "doug".

$ brew install imagemagick

Firefox

Add-ons:
```
SQLite Manager
```
Perian

www.perian.org/
WireTap Pro

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 - Vi¶ ↑

Toggle case under cursor
```
~
```
Show hidden characters
```
:set list
:set nolist
```
Multiple windows

www.cs.oberlin.edu/~kuperman/help/vim/windows.html
```
:split
ctrl-w arrow (move windows)
:hide
```

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
```

5c - Homebrew auto-updates¶ ↑

Homebrew auto-updates (github.com/Homebrew/brew/issues/288)

but 1.1.0 requires CLI > 4.0 (github.com/Homebrew/brew/commit/4015d0465a975aaac26d5a47395ab61e29d1702f)

In order to keep SnowLeopard running a bit longer (although the death-sentence is looming…)

Set 'brew' to 1.0.9 tag

$ cd /usr/local/Homebrew ; git reset --hard 1.0.9

'export HOMEBREW_NO_AUTO_UPDATE=1' in '~/.profile'

5c - Homebrew docs¶ ↑

(See 10 - Open file from Terminal)

5c - Homebrew commands¶ ↑

Revert to previous version of package 'readline'

$ brew info readline
$ brew switch readline 6.3.8

Edit brew formula
```
$ brew edit python
```
Reinstall formula
```
$ brew reinstall python
```

6 - Nested backticks¶ ↑

Use $(command) rather than `command`

eg:

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

Accessing OSX fs from linux¶ ↑

(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

http://dl.dropbox.com/u/35856129/x64patch-10.6.8.tar.bz2

$ cd ~/Downloads/x64patch-10.6.8 ; more readme.txt

System Software Overview:

64-bit Kernel and Extensions: Yes

Holding down 3 + 2 until Apple appears gives:

64-bit Kernel and Extensions: No

$ sudo diskutil unmount /Volumes/DISK0S3
$ diskutil mount /dev/disk0s3
$ diskutil info /dev/disk0s3
