Safari for Mac cannot correctly show PDF in the website.

I check my university website everyday, but there is a problem. PDFs which are embedded in the website cannot be shown correctly. In Safari, it is shown as a big grey area, and nothing is inside. In Chrome, it is shown correctly. Anyone knows how to fix this? :)

If the above doesn't work, are you running any anti - virus programs? Using a VPN?


Try setting up another admin user account in System Preferences/Users & Groups to see if the same problem continues. Please post back on whether or not this worked. Also try the Safe Mode. Please post back on whether or not this worked.

If it works in the Safe Mode, try running this program when booted normally and then copy and paste the output in a reply.

Greetings, JuhFaRee.


I see that you're not seeing PDF files being offered on your University's website when you use Safari on your MacBook Pro. They show up fine using Google Chrome, and I'm glad to help with this.


If Safari doesn't load a page or webpage items are missing -- This article provides the steps to use when Safari isn't displaying everything available on a website.


Take care.
