When trying to open osu! on mac OS high sierra, nothing happens. i tried various different methods to fix this and researched quite a bit, and i finally found a way to get it running (Note that this for the latest release of osu! not the stable release):
1. Download this version of osu! from gitHub, https://github.com/Mic238/osu-for-Mac-Stable-Latest - once this is downloaded, extract it
2. Download winseskin winery from here, http://wineskin.urgesoftware.com/tiki-i ... =Downloads
3. Open wineskin winery, and click 'Create a new blank Wrapper' - you can name this wrapper whatever you want, i named mine osu!
4. As the wrapper is being created, it will ask if you want to install 'gecko' - click 'install'
5. Once the wrapper has been created, right click on it and open wineskin, and click on 'set screen options' and under the heading 'Other Options', make sure the boxes 'Use mac driver instead of X11' and 'Decorate windows' are ticked and the other 2 boxes are not ticked.
6. Now go back on the main menu of your wineskin wrapper, and click 'install software' and then choose 'move a folder inside'. Navigate to the 'osu-for-Mac-Stable-Latest-master' you extracted earlier and choose this
7. Now it will ask you 'Please select which executable file is normally used in windows to start this program' - there will be a very long list of '.exe' files but try and fine the file that ends with 'osu!.exe' and choose this one
8. Once you have done this, close your wineskin window and quit your wrapper, and then re-open it again and osu! should start up. However, it will say 'Could not install .NET Framework v4' - leave it for now and x off osu!
9. now go back into the wineskin in your wrapper and click on 'advanced', then 'tools', then click on 'kill wineskin processes' just in case. Now click on 'winetricks' and in the search bar search 'video' then open settings and tick the box that says 'videomemorysize = 2048' and run this.
10. once it has been run, search for 'dotNet40' in the search bar and tick the box saying 'dotNet40' and run this. once run, it should open up a file saying 'dotNetFx40_Full_x86_x64.exe' and should also redirect you to a webpage. click off this webpage, but take this file and place it in your desktop (or anywhere else it is easily accessible)
11. click off everything, and open up wineskin again, click on 'install software', then 'choose setup executable', and find the 'dotNetFx40_Full_x86_x64.exe' file and choose this.
12. it should open up some 'microsoft .net' window but you should follow this and accept everything, and install everything. once everything from those windows has been installed, you should double click on your wrapper, and the latest version of osu! should be running on your mac![smile :)](https://osu.ppy.sh/forum/images/smilies/50.gif)
