Hi there SergeV
You're quite right – 1Password 8 requires macOS Catalina 10.15 or later. You can find a complete list of system requirements for 1Password for Mac here:
☞ System requirements for 1Password
The following models of Mac can run macOS Catalina:
- MacBook (Early 2015 or newer)
- MacBook Air (Mid 2012 or newer)
- MacBook Pro (Mid 2012 or newer)
- Mac mini (Late 2012 or newer)
- iMac (Late 2012 or newer)
- iMac Pro (2017)
- Mac Pro (Late 2013 or newer)
Depending on your Mac, you might be able to run a newer version of macOS, such as macOS Big Sur or macOS Monterey.
Let me know if you have any questions or need any further help and I'll be here. :)
