#### System Requirements

The current version of Sequin works with the following Windows versions:

- Macintosh OS 9
- OS X

It may work on other versions (MacOS < 9), as well.

#### Downloading Sequin

We provide a single download for both MacOS and OS X platforms.

1. Create temporary installation folder on your hard drive where you will place the downloaded Sequin installation file.
2. Download Sequin using your Web browser by clicking this link:
   sequin.Mac.hqx.
3. Your Web browser may show a dialog box asking if you want to run the program, or save it to disk. Choose Save to disk... and save the file in the installation folder.
4. If your Web browser can't download the file for some reason, see Troubleshooting.

#### Installing Sequin

Follow these instructions to install Sequin on Macintosh:

1. The file should automatically extract into a new file called sequin.Mac.sea. If it doesn't, use BinHex or UnStuff to convert it. Move the .sea file to your installation folder if it isn't already there.
2. Double-click the file sequin.Mac.sea. (It is a self-extracting archive.) This will create a folder called Sequin Folder in your installation folder.
3. Place the Sequin Folder in your Applications directory. This contains two versions of the Sequin, asn2gb, and tbl2asn applications (one with an "OSX" suffix and one without). It also contains the sequin.htm user's guide. The applications with the OSX suffix run only on Mac OS X. The other versions use Apple's "Carbon" library, and can run on both OS 9 or OS X.
4. To run Sequin, double-click the Sequin file in MacOS 9, or the SequinOSX file in OS X.
5. To run tbl2asn, double-click tbl2asn in MacOS 9, or tbl2asnOSX in OS X.
