For an excel and office computer it is good


Still use a 2009 iMac for just that
I have a MBP 2017 that is running OCLP and it’s purring along with the latest Sequoia update. Doubt it will wver run Tahoe or later, but it’s still quite useful.

Battery life is still good (knock wood) so I plan on keeping for another year or two.
