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.
The schools recommend windows or mac computers but not browser based computers like Chromebooks, basically because the software that they use for the education can’t be installed.
