 19  How to Upgrade
 20  ==============
 21  
 22  If you are running an older version, shut it down. Wait until it has completely
 23  shut down (which might take a few minutes for older versions), then run the
 24  installer (on Windows) or just copy over `/Applications/Bitcoin-Qt` (on Mac)
 25  or `bitcoind`/`bitcoin-qt` (on Linux).
 26  
 27  Upgrading directly from a version of Bitcoin Core that has reached its EOL is
 28  possible, but it might take some time if the datadir needs to be migrated. Old
 29  wallet versions of Bitcoin Core are generally supported.
 30  
 31  Compatibility
 32  ==============
 33  
 34  Bitcoin Core is supported and extensively tested on operating systems using
 35  the Linux kernel, macOS 10.10+, and Windows 7 and newer. It is not recommended
 36  to use Bitcoin Core on unsupported systems.
 37  
 38  Bitcoin Core should also work on most other Unix-like systems but is not
 39  as frequently tested on them.
 40  
 41  From Bitcoin Core 0.17.0 onwards, macOS versions earlier than 10.10 are no
 42  longer supported, as Bitcoin Core is now built using Qt 5.9.x which requires
 43  macOS 10.10+. Additionally, Bitcoin Core does not yet change appearance when
 44  macOS "dark mode" is activated.
 45  
 46  In addition to previously supported CPU platforms, this release's pre-compiled
 47  distribution provides binaries for the RISC-V platform.
