"Insufficient Disk Space" error despite 220GB free – v7.0.2.2

bertamason

Environment
• Mac mini (M1, 2020) – 16GB RAM
• macOS Tahoe 26.3
• App version: 7.0.2.2

Issue
Whenever I try to download video, I get an “Insufficient disk space” error, even though the destination directory has 220GB of free space.

I have already tried the following without success:
• Deleted and recreated the Temp and Output folder
• Restarted the app
• Restarted the Mac

Additional context
Just before this, I encountered the same error. An app update happened to be available at the time, so I installed it — after which roughly 10 downloads completed successfully. However, the problem has now returned.

As a workaround, I switched the destination to a different drive (with over 1TB of free space), which allowed downloads to proceed. However, I would prefer not to use that drive on a regular basis, so I am still looking for a proper fix.

I’ve seen many users reporting the same issue online, but no effective solution has been shared. Has anyone found a reliable fix?

bertamason Apple made macOS a mess with their lying file allocations &c, for example see:
https://stackoverflow.com/questions/49197692/getting-disk-space-attributes-nsfilesystem-attributesoffilesystem-doesnt-match

the short of it is: if you have less than 16(? can’t remember the exact figure off the top of my head)GiB of immediately allocable space, SF won’t start something when it guesses it might fail; and according to SF’s probing you had 13…

Generally, having the TEMP directory on your system SSD isn’t a good idea (especially given that Apple’s stuff isn’t meant to be replaceable); TEMP gets a fair bit (and by that I mean a lot!) of trashing…

This looks fine:
[default] "DiskSpaceCheck, GetDiskFreeSpace result : 662, path : /Volumes/{volumename}/Output"

But even though I am unfamiliar with Apple’s memory management ..
.. the problem is apparently this:
[default] "DiskSpaceCheck, GetDiskFreeSpace result : 13, path : /Users/{username}/Documents/StreamFab/StreamFab/Temp" [default] "DiskSpaceCheck, GetDiskFreeSpace result : 13, path : /Users/{username}/Documents/StreamFab/StreamFab/Output"

However all dl in log are successfully or not?

The log does include the part where switching to an external drive worked.
As I learned from another reply here, macOS doesn’t report free space accurately. I didn’t realize that 13 was in gigabytes — good to know, thanks!

Thanks for the link! I had already come across that thread, but in my case restarting didn’t fix it. And honestly, I wouldn’t have expected this to happen with 220GB free — 20GB maybe, but not 220.

Classic old skool advice: To fix the “not enough disk space” error on macOS, immediately empty your Trash, delete large unused files in your Downloads folder, and clear app caches by going to ~/Library/Caches in Finder. For immediate results, use the built-in storage tool: Apple Menu > About This Mac > Storage > Manage (or System Settings > General > Storage).

Ha, old skool indeed! Thanks!

Thanks for the clear explanation!
Really helpful to know it’s a macOS issue and that moving Temp to an external drive is the way to go. I’ll do that.

simchris

Yeah. I use an external drive for temp/cache and output to not kill my NVME. One caveat on Mac is avoid Fat32 with USB drives.
