Font Book Not Installing Fonts

My Mac decided to delete all but 19 fonts, which is fairly annoying. It didn't really delete them, as in I still have the original files in the /Library/Fonts folder, but they've disappeared from Font Book, so I can't use them.

Now, Apple says that you can select a folder to install all fonts in that folder, but when I try that, the spinning wheel (not the beach ball) comes up in the lower right hand corner for a few seconds and then leaves, without installing any fonts. The same thing happens if I use the + sign in the menu bar, select multiple, or if I try validating and then installing (actually, that installs one font).

  • Odd fonts displaying? When applications display content in odd fonts that have not been assigned to them, often this is caused by font corruption, duplication, or other problem with.

That is correct, it acts like it wants to do it, but the pop up screen flashes on and off and never stabilizes (the install progress bar) and sometimes I got the verification screen and even then going through the proper sequence, when completed, no fonts are listed in the font book.
  • Can anyone help me with advice on installing fonts I have downloaded on windows 10. I have read other people have a similar problem but haven't seen an answer that helps me. The 'File' drop down box in Fonts is supposed to have 'install new font' but it doesn't. I am not a 'techie'. But can follow most instructions. Rosie (70 years young).

Select Font Book when it appears from the Open With menu. FontBook will pop up with a little window for installation. Click the “Install” button. Similarly, you can copy/paste the font file directly into your computer’s font folder. Command+Shift+C will bring up your computer.

Is there any way to mass-install these fonts or will I have to install them one by one?

System info: Mac OS X 10.5.8 running Font Book 2.1 (123).
