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.
Open source software might not directly be used in the workplace but if someone can’t adapt from LibreOffice to MS Office they won’t be able to adapt to MS Office updates either. It’s been decades since productivity software had significantly different feature sets for most users. That weird legacy Excel formula the Finance Department uses will need training no matter how many years of Office experience a new hire has.
Alright but we’re not going to teach people both and we’re not going to teach people neither, so you shouldn’t be surprised that a large institution picked the corporate product.
