Retrieving CPU data from the Mac OS X command line is actually quite easy, although the commands used to get CPU data may be unfamiliar to many. We show two ways to grab Mac processor details from the MacOS and Mac OS X command line. These tricks work on virtually all versions of Mac OS. The easiest way to perform an Undo on Mac is with a keyboard shortcut: Command + Z Simply press Command and Z together and the last action, typing, or activity will be 'undone' on Mac OS. Note that some apps have multiple layers of Undo, meaning you can continuously Undo and revert back various steps and actions or typing.

When first booting up a Kusama node, it may take a while for it go get in sync with the latest block. Depending on how long the chain has been alive, your hard drive speed, your bandwidth, and some other factors, it can take days.
To save time, you can import a database that's already fully synced. First, you need to be aware of the two types of database supported by any Substrate based chain, including Kusama.
- RocksDB is the industry standard, and used in most blockchains. It's one of the fastest databases out there, is extremely lightweight, and has good compression. This is currently the default.
- ParityDB is a new database, custom built for blockchain data. It performs better in this niche than any other database out there, but at the cost of storage - it takes up much more disk space.
Either is fine, though ParityDB is preferred as it's likely to become the default soon.

Importing the Database
We assume you have a working Kusama or Polkadot node on your machine. If you are on Linux-based systems or the WSL (Windows Subsystem for Linux), you can download a pre-built Kusama node (Linux binary) from the release page. While it is possible to compile and run a node on native Windows and Mac OS, it is not recommended for long-term stability, as those operating systems are not built for long continuous operation.
The node needs to be run in archive mode, so the option --pruning=archive needs to be appended unless you're running a validator in which case it's the default.

Elifoot 18 pro mac os. Here's an example command to run the Kusama node provided you're in the folder which contains the binary:
As stated earlier, this will default to RocksDB. Yoba (itch) mac os. To use ParityDB, use:
Kusama Kommand Mac Os Catalina
The database folder will be created in ~/.local/share/polkadot/chains/ksmcc3 by default, with ksmcc3 replaced by polkadot if you're using the Polkadot chain. If you used RocksDB, there will be the folder db. If you used paritydb, there will be the folder paritydb.
You will need the 7zip program to unzip this. First, rename the downloaded file from Qm.. to archive.7z. Now simply uncompress the previously downloaded archive in place of the appropriate folder (make sure the node is not running before doing this). The output of the decompressing will be the folder (db or paritydb) so you can just uncompress into the ksmcc3 / polkadot folder directly. This is probably easiest to do through a user interface, but if you want a command:

Now relaunch your node with the desired db option, and it will continue syncing from where this archive left off.
