# OS X 10.5 (Leopard) and 10.4 (Tiger)

## OS X 10.5 (Leopard) support

Starting in version 3.6, 1Password requires OS X 10.6 (Snow Leopard) or OS X 10.7 (Lion). While we stopped adding new features to OS X 10.5 (Leopard) versions of 1Password, older versions of 1Password are available for Leopard.

We highly recommended that all customers update to OS X 10.6 Snow Leopard, which will be required for OS X 10.7, in order to keep up with the latest security updates and web browsers.

If you are unable to upgrade to Snow Leopard, please download an older version of 1Password which still supports Leopard.

## OS X 10.4 (Tiger) support

While 1Password 3 requires Mac OS X 10.5 (Leopard), 1Password 2 supports Mac OS X 10.4 (Tiger). Tiger users can download 1Password 2 here.

## Commonly asked questions

### How can you drop Snow Leopard support already? Lion isn’t even released!

Snow Leopard (Mac OS X 10.6) is still supported. It’s the other Leopard that is no longer supported, namely Mac OS X 10.5. This is one of the few times Apple used confusing code names for their big cats :)

### Can I sync my Lion, Snow Leopard, Leopard, and Tiger machines?

The data files in the Tiger and Leopard versions of 1Password are compatible with the newer versions on Snow Leopard and Lion, so you can sync your data between any combination of Tiger, Leopard, Snow Leopard, and Lion machines.

Simply setup an sync solution like Dropbox on all your machines and your 1Password data will automatically stay in sync.

### Why don’t you “support” Leopard? Will you answer my emails?

We love our users and know Leopard and Tiger are still needed so we’ll continue to support you. The only difference is we have stopped developing new features for these older platforms.

Leopard users are free to continue using older versions of 1Password and we continue to answer questions from users who need help. In fact, we still answer Tiger questions!

### Where do I download the old version?

Older versions of 1Password are available for Leopard and Tiger. Download them here.
