This is my main unix operating system I use daily. Listed here are a few things to make it more useful.
macOS 10.11 El Captain, issues with Homebrew
To regain access to /usr/local
sudo chown $(whoami):admin /usr/local
You also need commandline tools and/or might need to point to them:
xcode-select --install xcode-select --switch /Applications/Xcode.app
I installed the Beta version of Xcode 7 and for some reason had to switch the links to the real version.
You can use the command line to update your macOS systems remotely:
|-l, --list||List packages available|
|-i, --install arg|
Install packages where arg can be:
|--schedule arg||Setup scheduling downloads, either on or off|
Step 1: On your Mac, first open the Preferences panel. There, head to the Accessibility option as shown below.
Step 2: On the left panel of the next window, scroll down and select the Mouse & Trackpad option. There, click on the Trackpad Options… button.
Mouse and Trackpad
This will bring down an options panel.
Step 3: On this panel, you will notice an interesting option at the bottom named Enable dragging. Check it.
Preferences Enable Dragging
This option not only allows you to enable dragging on your Mac’s trackpad, but also lets you activate or deactivate drag lock (when enabled, this means that when you drag a window, you will have to perform one more click in order to deactivate the drag function).
And done! Now whenever you use your Mac’s trackpad, just double-tap on any ‘draggable’ area of a window to move it around.
Stop Safari re-opening windows
Hold the shift key down and open Safari
defaults write com.apple.Safari ApplePersistenceIgnoreState YES defaults write com.apple.Preview ApplePersistenceIgnoreState YES
Stopping App Store Downloads
Pausing downloads is easy, but if you start one and want to cancel it hold Option key and click on cancel.
My hard drive crashed (29 April 2015) and I had to re-install everything. Oh, a USB drive attached to Airport Extreme as your Time Machine backup doesn't work! When I tried to reinstall from that, it complained about corrupt Time Machine files or some such crap. Connect your drive directly to your computer.
So, here is all the software I had to re-install:
Some useful programs:
- arp-scan: find hosts
- arping: find hosts
- cmake: build software
- htop-osx: colorized top
- nmap: network mapping
- pandoc: swiss army knife of document conversion
- pcap: capture network packages
- pkg-config: build software
- python: language
- ruby: language
Note: Although I install languages like python, I use pip to handle python packages.
