So it doesn’t work…
Or, at least, DaisyDisk doesn’t work as expected.
Below you can find a few hints that may help you fix your issues.
DaisyDisk is not a general purpose Mac maintenance utility, but it never hurts to ensure your system works properly.
Restart your Mac. Sounds stupid, but it may help.
For general purpose maintenance we recommend Onyx, a free and useful tool. Just don’t blame us if you misuse it :)
If you keep getting Timed Out error messages, try the following:
Check local disks with the Disk Utility. Timeouts on your Mac HD often indicate problems with permissions or file system integrity.
Reduce the number of files on your SMB shares. Accessing an SMB folder with a large number of files requires a lot of time for any application (not just DaisyDisk). Reducing the number of files in the folder by archiving them may solve the problem.
Try accessing the resource via a different protocol or scan them locally. Some network resources decline access after receiving a significant number of requests necessary for scanning.
It looks like headless Mac servers do not load graphic drivers that are necessary for applications, powered by Core Animation (all of them, not just DaisyDisk). As a result, portions of the UI appear black or do not refresh.
Plugging in an external display solves the problem. You can also try hacks that
emulate displays, but do it on your risk.
Scanning disk as administrator may be helpful once you have problems with large amounts of disk space inaccessible to normal users.
Some backup tools are known to leave garbage in /Volumes folder. Check it with Terminal app.
