MacOS 11 (Big Sur) support

[SOY75]

Hello everyone!

I’m about to migrate from 1Password to Bitwarden.
I was unpleasantly surprised to find that the latest versions of Bitwarden Desktop are no longer compatible with macOS Big Sur.

I found a 2025 version of Bitwarden on GitHub that works perfectly, but it auto-updates after a few days of use.
Is there a way to block updates?

I have Little Snitch as a firewall, but I don’t know which host to block…
I’ve seen some threads mentioning that it’s possible via flags, but I didn’t understand how to modify that.

(OpenCore Legacy Patcher is not an option the Mac has to stay on Big Sur.)

Thanks in advance!

Apple also no longer supports MacOS 11 (Big Sur)… and Bitwarden…:

Hm… There was this announcement a while ago:

To provide the best security and support, Bitwarden will soon enforce its long-standing software release policy. Please update your Bitwarden clients and server regularly to stay secure and maintain access. More details to follow.

Less time spent maintaining old versions allows the team to deliver new features faster and more reliably.

For those self-hosting, older client/server pairs can still run (not recommended, but you can if you absolutely need to) — updating to the latest versions available is always recommended for security updates and support eligibility.

Essentially, every version that is three or more major versions behind, is considered out-of-support now (and not necessarily compatible to the latest server versions):

And my impression is, that there are more breaking changes to come, which will not even make it possible to use many older and out-of-support client versions… (e.g. changes with vault/item encryption etc. on the server side will make it impossible for older clients, that don’t support those changes, to connect to the BW servers)

I guess I don’t really have much choice but to stick with 1Password for another year in that case, or else just use the bitwarden Firefox extension.

I’m not sure what you’re doing, but from what I see the current 1Password app also needs at least MacOS 12.

Definitely!
