[bug] update.downloadAndInstall does not work on removable volume [macOS]

[martingrzzler]

Describe the bug

I've added the updater plugin. Upon calling downloadAndInstall on a build that is stored on a removable volume, everything completes without errors but the files on disk aren't updated. So when I reopen the app, the update is attempted again indefinitely.

Edit:
I've found the error.

 Os { code: 18, kind: CrossesDevices, message: "Cross-device link" }

It is thrown here when trying to rename the extract_path to the tmp folder.

Oddly this error doesn't make it to the frontend.
I guess one would have to create the tmp dir on the removable volume.
