mid-2012 mac can't update to newer OS
Hi, I'm trying to upgrade to a newer OS but can't succeed in it. I'm currently using macOS Catalina (10.15.7) on MacBook Pro (mid-2012).
I've tried to upgrade to Sonoma from App Store, but I keep getting an error "the requested version of macOS is not available.". Is it not possible with an older mac to upgrade to a newer OS? I remember this same issue happening with Monterey and Ventura too (and thus I'm stuck with Catalina).
The computer hardware works just fine (despite being a grand old mac!), and it would be a huge shame to stop using it just because there is no newer macOS available for an elder hardware.
MacBook Pro 15″, macOS 10.15
