Re: Can't install LyX 2.5 on an old Mac

Alternatively, install Open Core Legacy Patcher
<https://opencorelegacypatcher.net/download/> on your machine so that you
can run a more recent version of MacOS. Versions through Sequoia are
currently supported. Just be sure you keep abreast of the latest
developments and issues with Mr Macintosh on YouTube.
