7 | # MEGA D/l 
8 | **macOS workflow and shell script to download files from public mega.nz shares using the megatools**
9 |
10 | Minimum OS: **OS X 10.8**
11 |
12 | * click on a MEGA URL (or select a bunch of MEGA URLs), and select **Download from MEGA** from **Services** in the contextual menu
13 | * on first run, **MEGA D/l** will ask you to select the location of your MEGA download folder
14 |
15 | You can reset your download folder choice by running the following command:
16 |
17 | `rm -rf $HOME/Library/Preferences/local.lcars.MEGAdl.plist`
18 |
19 | After that **MEGA D/l** will let you select a different MEGA download folder.
20 |
21 | ## Installations
22 | ### megatools [prerequisite]
23 | More information: [megatools](https://github.com/megous/megatools)
24 |
25 | * install using [Homebrew](http://brew.sh) with `brew install megatools` (or with a similar manager)
26 |
27 | ### Main installation
28 | * [Download the latest DMG](https://github.com/JayBrown/MEGA-D-l/releases) and open
29 |
30 | #### Workflow
31 | * Double-click on the workflow file to install
32 | * If you encounter problems, open it with Automator and save/install from there
33 |
34 | #### Main shell script [optional]
35 | Only necessary if for some reason you want to run this from the shell or another shell script. For normal use the workflow will be sufficient.
36 |
37 | * Move the script `megadl.sh` to e.g. `/usr/local/bin`
38 | * In your shell enter `chmod +x /usr/local/bin/megadl.sh`
39 | * Run the script with `megadl.sh ''` (it has to be in your $PATH)
40 |
41 | ### terminal-notifier [optional, recommended]
42 | More information: [terminal-notifier](https://github.com/alloy/terminal-notifier)
43 |
44 | You need to have Spotlight enabled for `mdfind` to locate the terminal-notifier.app on your volume; if you don't install terminal-notifier, or if you have deactivated Spotlight, the MEGA D/l scripts will call notifications via AppleScript instead
45 |
46 | * install using [Homebrew](http://brew.sh) with `brew install terminal-notifier` (or with a similar manager)
47 | * move or copy `terminal-notifier.app` from the Homebrew Cellar to a suitable location, e.g. to `/Applications`, `/Applications/Utilities`, or `$HOME/Applications`
48 |
