Apple Macintosh OS 10.5 (Leopard) -- Single File Instructions

The single file cannot be delivered by the usual method of using a web browser. To download the file, use a "real" FTP client -- either the built-in FTP client in Mac OS via the Terminal program or a program like Fetch. The following steps demonstrate using the built-in FTP client:

1. Launch Terminal from /Applications/Utilities

2. Type in: ftp isdp.nih.gov

3. When prompted, type in your username -- remember to precede your username with: NIH\

4. When prompted, type in your password

5. At the ftp> prompt, type in: binary

6. At the ftp> prompt, type in: lcd ~/Desktop

7. At the ftp> prompt, type in: cd /files/test/SBO_1/Apple/OSX

8. At the ftp> prompt, type in: get leopard.dmg

9. After the file is downloaded -- this will take some time -- type in: bye

10. Type in: exit

11. Quit Terminal

12. The leopard.dmg file can now be used to make a bootable dual-layer DVD of Mac OS 10.5
