Lightroom sem compatibilidade com MAC high sierra

[jessica256058722of6]

Sou fotógrafa e tenho um macbook pro 2011 com sistema high sierra não atualiza mais, estou tendo problemas com o lightroom pois não encontro a versão que seria compatível com o sistema. Como resolvo meu problema?

LR Classic 9 is the last version that runs on Mac OS 10.13. Unfortunately, Adobe only provides installers for the last two major versions (10 and 11). 

You can download LR Classic 8 from here:

https://prodesigntools.com/adobe-cc-2019-direct-download-links.html

(That site is quite reputable and often referenced in this forum.)  Double unfortunately, that site doesn't provide installers for LR Classic 9 (since Adobe stopped making them available).

Beware that Adobe only provides support for the most recent version (LR 11).
