I have a collection of fonts dating back some years that I keep in my Font Folder in my User's Library Folder. Most of these are in Suitcases and I presume are Bitmap fonts that I had used in Mac OS 9 and prior OS's. I am currently running OS 10.4.10 on an Intel MacBook (as the "Administrator").

The problem is that Font Book does not recognize any of them in its Font Panel. However, when I do a "Validate File..." from the Font Book "File" menu and navigate to my Fonts folder (~/Username/Library/Fonts), it shows all the fonts, allows me to select them in the Finder, to validate them (most pass the validation check), but when I click on the "Install Checked" button—nothing happens.

Does this mean that the fonts are too old for use in OS X or what?

Furthermore, for those fonts that do NOT pass the validation check, does this mean they should not, under any circumstances, be installed (assuming they could be)?
