Level 41 in the dark

I'm playing on a Mac Book Pro, OSX Yosemite.

On level 41, there is a black screen with exclamation marks. The task is to pick up all the boxes the crew left behind. You can click on these exclamation marks and do the task. I managed to finish the task but there still is a black screen. There is no way to finish the level and/or move on. Please fix. Thank You.

Same here. Playing on Macbook Pro, 15in 2016 OS Sierra 10.12.3
Any fixes? Can't go any further.

I have the same problem - black screen with exclamation points. Tried clicking on all of the exclamation points and they disappear, but then nothing else happens. This has evidently been a problem for some time - when will there be a solution? Also playing on a MacBook Pro Sierra 10.12.4

i found one interesting thing to avoid the dark, you CAN't click the skip, let it run through, you can then play. hope this would help.

Thanks, Charles! Your tip worked for me and I am now able to move on in the game.
