Error after changing resolution

[nbolton]

I'm seeing this error on first time use of the app:

From memory, steps to reproduce (not verified):

1. Set resolution to 1600 x 900 during initial config
2. Select macOS 13.4.1 and wait for download to complete
3. Before starting, check settings and see that resolution was actually 1621 x 900 (or something like that)
4. Change resolution back to 1600 x 900
5. Error appears

I think it's related to discussion #69

Ah, I guess not related to the resolution. Perhaps I accidentally increased the resolution?

Anyway, I'll try this solution for the error: #69 (reply in thread)
