Here is the story behind , a version that holds a nostalgic place in the timeline of scientific publishing.
Because MathType was expensive (~$97 for a student license in 2013), many students used keygens. For versions 6.7 and earlier, those keygens worked fine.
In 2017, Apple released macOS High Sierra, which broke 32-bit app compatibility. MathType 6.8 for Mac (which was a Carbon app) simply refused to open. Design Science told users: "You must upgrade to version 7, or buy a subscription." mathtype 6.8
However, a major European university purchased a site license. A student inadvertently leaked a Volume License Key (VLK) for 6.8 to a popular cracking forum. Because 6.8 didn't "phone home" for every launch (it just checked the key format), that single VLK worked for millions of users worldwide for nearly 5 years.
Design Science tried to patch it with 6.8b, but the damage was done. To this day, if you find an old "MathType 6.8 full crack," it is almost certainly that university's legitimate key floating around. Here is the story behind , a version
Here is the specific story associated with 6.8:
MathType 6.8 was a "polish" update. By this time, Microsoft Office 2013 had changed the rules. Older versions of MathType often crashed or inserted garbled equations into the new docx format. Version 6.8 was the hero that fixed this. In 2017, Apple released macOS High Sierra, which
Thousands of scientists refused. They stayed on Windows 7 or older Macs just to keep MathType 6.8 running.
