I tried installing this last night but hit a brick wall.
I ed, extracted and moved the app, but it doesn't launch at all.
Double clicking the app (in Finder) plays the launch animation (eg: the icon grows and fades) but nothing appears on the dock at all. Rick-click open, and opening from the dock does nothing either.
Reading some of these posts, I opened WS to test run, but after completing (I should add, nothing actually seems to happen when the test is running either), the test log doesn't show when I click "view" in the dialog box.
The logs also don't appear when I go to Tools > View Last Run Log Files.
I'm looking through the "DIY" guide to see if theres any discrepancies, and I'm currently ing WS9Wine2.22 to see if that helps (I had WS9Wine1.11)
Will report back if/when something changes.
[Edit: post merge]
This is what I've done so far (after my last post), with results:
...
DID: Install WS9Wine2.22, set it as the engine.
RESULT: No launch, no test run results.
DID: "Use Start.exe"
RESULT: No launch, no test run results. (I've since unenabled it)
DID: Winetricks > .NET 4.0
RESULT: No launch, no test run results.
DID: Install Software > osu!.exe
RESULT: "Executable not found!" error. No launch, no test run results.
NEXT: ??? I'm out of ideas.
[Edit 2]
I found the problem! The file permissions on the folder I had it in were a little janky!
If you can't get it to launch, try one of these solutions:
Run First Aid on your drive
1) Open Disk Utility by searching in Spotlight or finding it in Applications > Utilities.
2) Select your drive, usually called "Macintosh HD".
3) Click First Aid in the bar on the top of the window.
4) Press "Yes/OK" if it warns that the computer may slow down while the test is running. It is possible this could happen, especially if you put the computer under heavy load while it's running. The test should take no more than 5 minutes.
5) Keep running it until it stops giving errors (The "Exit Code" should be 0).
6) Try opening Osu! again.
NOTE: Quite unlikely, but if the Exit Code is 8, or it complains of being unable to fix the drive, back up all of your data immediately and be prepared to take your computer to Apple for servicing (or be prepared to fix it yourself, where possible).
Manually change the permissions of the folder
1) Locate the folder in Finder.
2) Right-click on the folder and click "Get Info".
3) At the bottom, extend "Sharing and Permissions".
4) Click the lock and enter an (if needed).
5) Select your name in the list and ensure it says "Read & Write".
6) Select the System item in the list and ensure it has Read & Write permissions.
7) If the folder is shared, or you are part of multiple groups, use the plus icon to add these to the list and give them Read & Write too.
8) Click the lock again, then try opening the app.
You can also use this method on the Osu!.app itself, but I prefer to re-perm the whole folder.
Create the file in a different location
Even if you've not left it in s, you might have issues opening it for similar "system integrity" reasons, so:
1) Delete the .app file.
2) Move the .zip to another location, like your desktop.
2) Unzip it here.
3) Open it. If it launches, let it install.
4) , then close the app.
5) Wait for it for to disappear from your dock, then move it to your location of choice.
6) Try opening it again.
If this fails, try: Leaving it in the location it opened in, but right-click, make an alias, and move the alias to the location you want it to be in. Be aware that some security programs, might have "Quarantined" the app, or marked it as a virus or something. Have a look to see if you can "allow" it to run.
My permissions are a little messed up as I've recently had to keep pulling my files off and replacing them because my hard drive is failing (Exit Code 8!) but I'm too
stingy poor to have Apple put a new one in, but these steps should help anyone with permission problems.
I've heard theres some apps that automagically fix file permission issues, but I've never used them and cannot vouch for their efficacy.
Hope this can help anyone who's struggling to open the app!
