Binaries

  1. Download Truck Cargo Packing for macOS 10.11 or later and enjoy it on your Mac. ‎Find the best layout to pack your truck's cargo with boxes quickly. Simply enter the cargo space dimensions, dimensions of the boxes and let the app do the packing.
  2. Mac OS X Server 10.5 – also marketed as Leopard Server; Mac OS X Server 10.6 – also marketed as Snow Leopard Server; Starting with Lion, there is no separate Mac OS X Server operating system. Instead the server components are a separate download from the Mac App Store. Mac OS X Lion Server – 10.7 – also marketed as OS X Lion Server.
  3. Start your Mac holding down Command + R. Prepare a clean external drive (at least 10 GB of storage). Within OS X Utilities, choose Reinstall OS X. Select external drive as a source.
  4. The Home folder is the most valuable part of Mac disk space since it stores all the documents, applications and other files the Mac user has. We hope our article helped you to understand a bit more deeply the structure of the Home folder and how to work with subfolders in it.

There are a few ways of proceeding here. You can build OpenEthereum from the sources; you can launch OpenEthereum using the binaries built for the latest releases for Linux, macOS and Windows or, if you’re on an Ubuntu Snappy platform, just use our Snappy App. Other Unix-like environments should work (assuming you have the latex *nix installed); we’re not going to expend much effort supporting them, though build PRs are welcome.

Homebrew (macOS)

  • brew tap openethereum/openethereum
  • brew install openethereum

Manual

Fortunately, if you have lost your password, there are several approaches you can take for either regaining complete access to your Mac or, at least, getting to the specific data you need.

Binaries for OpenEthereum are provided. If you’d like to try these out, downloads are available on the Releases page.

  • Linux
    • Download the latest release from the link above
    • Make the openethereum file executable by running chmod u+x openethereum
    • Launch OpenEthereum with your favourite flags: ./openethereum --chain dev --jsonrpc-apis personal
  • macOS
    • Download the macOS binary.
    • Open a terminal and navigate to the directory using cd /path/to/binary/folder/.
    • Make the binary executable by running chmod +x openethereum.
    • You can now double click on the binary.
  • WindowsDownload the binary and double click on it.

Dependencies

For Linux systems:

  • Ubuntu, Debian

  • CentOS

Building from source

To build OpenEthereum from source follow the instructions in the README.

For Ethereum key management Ethstore can be used. To compile it use

in the root OpenEthereum directory and for usage instructions:

Building using Docker

Docker is great for making sure differences between operating systems, distributions, installations and build environments don’t get in the way of coding fun. For this quick start, we’ll use docker to set up a minimal Ubuntu installation and take it from there. However, you don’t need Docker - similar instructions can be used to get things working on pretty much any Linux installation or a Mac Homebrew system, just don’t come complaining if it doesn’t work for you on some niche distribution (Arch, I’m looking at you!) or *nix with 6 months of cruft caking it up. Instead, get the docker image working and then figure out what the differences are.

NOTE: Ensure you have docker to begin with.

This will give you a temporary docker environment.

Grab Rust

NOTE: If you already have Rust in your environment, you don’t need to bother with this.

This will download and install Rust on Linux and OS X:

If you are using Windows make sure Visual Studio 2015 with C++ support is installed. Ensure you run all of the next stuff in the VS2015 x64 Native Tools Command Prompt.

NOTE: We do not support the GNU toolset on Windows. Do not install it, and do not install any Rust version that uses it. If you see x86_64-pc-windows-gnu anywhere, you’ve done it wrong!

Download and run rustup and use the following command to setup the MSVC toolchain:

Install and Build OpenEthereum

Next, grab the OpenEthereum repository:

For tests, also update submodules:

You can build with:

You can run the unit tests with:

You can run just the consensus tests with:

To install OpenEthereum on Linux and Mac OS, just build it and copy it to /usr/local/bin:

For Windows, use copy it into C:Windows:

You can start a client and sync with the network with:

To get help on the command line options for the openethereum client, use --help:

A note on backing up your datadir with Docker

In case you need to persist the blockchain files, keys etc., you should run the image with the --base-path option and then mount it, e.g.:

Things to check first

Check if you still need help after each of the steps below.

  1. Check the system status of iCloud Contacts, Calendars, and Reminders.
  2. If a reminder isn't showing up on some devices, make sure that you're running the latest iOS, iPadOS, or macOS on each device. Upgraded reminders and shared reminders in iOS 13 or later or macOS Catalina or later aren't compatible with earlier versions of iOS or macOS. Learn more.
  3. Make sure that the date and time settings on your iPhone, iPad, iPod touch, Mac, or PC are correct.

  5. Check your Internet connection. Open Safari and go to www.apple.com. If you can’t open the page, learn what to do.
  6. Check that you can access secure websites. Open Safari and go to your Apple ID account page. If the website won't open, contact your Internet service provider for help.
