A font that looked fine in pre-OS X Mac systems, looks weird or has no spaces when you install and use it in Mac OS X.
Solution: Make your old fonts future proof with .otf
If you use Font Book [Lettertypencatalogus]:
First close all applications.- Search for installed copies of the font with the Finder’s Search and remove them from all system font folders.
- Open the font with FontLab 4.5 or higher (or your own favorite font manipulation application). This doesn’t work with all kinds of file formats.
- Choose from the File menu; Generate Font.
- From the popupwindow Font Format button, change ‘FontLab’ to ‘OpenType-CFF’ and save the file.
By The Way: Do yourself a favor and choose a descriptive name, like TemplateGothicBold instead of temgotbol or something like that and avoid spaces. OS X doesn’t have a problem with spaces, but a lot of others systems, like web servers may.
Double-click the new .otf file and install it by clicking the button in the popup window. Double click the .otf file to instal it in OS X.
