Sorry for the Danish post i hope you can translate it.
The Ministry warns that Microsoft programs can create problems for written exams for students with Mac computers.
Users who have updated the programs to the latest version may experience the programs running slowly, freezing and crashing. This means that the examinees are delayed in their work and that parts of the answers risk being lost, write the Agency for Education and Quality and the Agency for IT and Learning in a notice to schools.
It was pretty buggy though, my class had people’s laptops permanently locked into the browser and unable to close it after the exam. Sometimes it wouldn’t even let you start the exam even after launching with the browser until you restarted the whole system.
