How to find Mac OS 9 downloads?
As of the posting of this tip, the Mac OS 9 downloads on Apple's support site are not fully available.
This tip of a method of obtaining the downloads was suggested by sdfox7. Special thanks to them for decoding
how to discover old downloads.
Locate the support.apple.com website for the download. In the case of most of the system downloads for Mac OS 9, there is this link:
http://support.apple.com/kb/HT1387
and
Older Apple software downloads
In event the link doesn't work, go to http://web.archive.org/ to find it. For this link, the example site is:
http://web.archive.org/web/20100917074207/http://support.apple.com/kb/HT1387
If you are looking for the 9.2.2 download, the direct link from that page is
http://web.archive.org/web/20101204032737/http://docs.info.apple.com/article.htm l?artnum=75186
Clicking through
http://web.archive.org/web/20101204032737/http://docs.info.apple.com/article.htm l?artnum=75186
First on the page you will find North American English, 9.2.2, 21.3MB.
When you right click, or control-mouse button the download link and select copy link, you obtain:
Edit this link to reveal just the file name and not the path going to it and paste it in your favorite search engine. In this case, the file name is:
Mac_OS_9.2.2_Update.smi.bin
Searching you'll find that this link has that download.
Intl English (Z)-Mac_OS_9.2.2_Update.smi.bin
As it happens, the website:
http://mirror.macintosharchive.org/max1zzz.co.uk/+Mac%20OS%20Classic/Operating%2 0Systems/
has the download links for all the Mac OS 9 updates and others.
You can use a similar method for many other downloads of older software.
As I also found out, .bin files even Mac OS X 10.9 understands. .smi files Disk utility won't open in Mac OS X 10.9, but it will convert to .dmg files.
If you copy the contents to a USB Flash drive of the same name as the dmg file (without the suffix), it can hold the installer in question and connect older Mac OS 9 machines to run the installer from. Just make sure the USB drive is formatted HFS+ no journaling, or FAT16 and under 4GB in size.
The other thing to note, is that no Mac running Mac OS X 10.3 or higher supports the old style floppy disks of under 1.4 MB. The beige PowerMacs were the last that supported the 800k floppies with the single notch on the the corner. If you have floppies with two notches on either corner of the label, then they are 1.4 MB.
1.4 MB floppy looks like:
400k and 800k floppy look like:
Note how the 800k only has one notch for the write protect tab, and no other opening on the other corner.
