Hi! I just buy a MacBook Pro. Now I want to install some fonts from this website, like I did before!
Now he says that he cannot download it because it’s not a registed Apple font.

Do I must go change anything?

Can you provide the exact phrase of this warning?

He says in Dutch:

Lettertypen niet geïnstalleerd

Lettertype kon niet worden geïnstalleerd.
Dit kan gebeuren als er geprobeerd wordt lettertypen te installeren vanuit bestanden die geen geldige lettertypen bevatten.
Controleer je selectie en probeer het opnieuw.

There's nothing about the font not being a "registered apple font" like you said in your previous message.
Deepl translates your message as


are you sure you unzipped the fonts before you tried to install them?

It's not a zip file. Directly a OTT file

What font ? OTT or .otf

.otf, sorry!

what font are you talking about?
not funny we have to worm all the informations out of you, it looks like you don't really want to be helped...

That is not my intention. I hope that you can help me out. Mac is for me a new system. But I need for my work the fonts from Dafont.

When I download a font, no matter what kind of file. But take for example A .otf. I click on it and he opened it on the font book. He validate the font and I click on install. Then I get the warn like I told you before. Strange.. I really don't know what to do. Can I send picture of it?

What error on FONT Book?

Use imgur to upload an image, then post the image link here.
Maybe someone with a Mac will be able to help you (I stopped using Apple computers 23 years ago).

As this is a Mac related problem (and not a font problem), did you search on apple.com?
Looks like someone had the same kind of problem and found a shitty fix https://discussions.apple.com/thread/254463197

Thankyou Marty! Apple send me to Dafont. But I will look. Thankyou!

looks like the solution worked?
