Choose a correct keyboard layout for login window
Before logging in verify that the keyboard layout at login window is correct and supports the layout you are using in Metropolia.
By default the keyboard layout in Macs is Finnish (Swedish have the same layout).
You can verify the current keyboard layout from the top part of the screen:
You can change the keyboard layout by clicking the keyboard icon and choosing the preferred one from the popup menu named "Other Input Sources".
This change will only be temporary as the layout defaults to Finnish after computer restart.
Beware of illegal characters
Please ensure that your password does not contain any illegal characters!
When logging in, Mac considers these characters as illegal in user password:
| ^ | (Caret, circumflex) |
| ¨ | (Diaeresis, umlaut) |
| ' | (Apostrophe, quote) |
| * | (Asterisk, star) |
If you have any of those characters in your Metropolia account password then you need to change your password to such that does not include any of those characters.
You can test the keyboard output by typing your password to the field "User" in login window.
However, to protect your account security you should do this only when nobody else can see what you are typing.
Active Directory client in macOS differs form Windows
Also note that Macs may require the user has changed password at least once before login is allowed (the initially created account password may not be enough).
This is not yet confirmed but still changing your password may be the easy solution for login problems with Macs.
Password change is the proposed solution
So if you have verified that your current password does not contain any illegal characters then you should change your password anyway.
