 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 in some cases), 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 data directory 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
 35  using the Linux kernel, macOS 10.12+, and Windows 7 and newer.  Bitcoin
 36  Core should also work on most other Unix-like systems but is not as
 37  frequently tested on them.  It is not recommended to use Bitcoin Core on
 38  unsupported systems.
 39  
 40  From Bitcoin Core 0.20.0 onwards, macOS versions earlier than 10.12 are no
 41  longer supported. Additionally, Bitcoin Core does not yet change appearance
 42  when macOS "dark mode" is activated.
