Some programs write to the macOS TMPDIR that is on the booth volume, but unfortunately, some write huge files on it (for scratch disk, Lightroom for example) and this depletes the available space, but more importantly the remaining HD space on the boot volumes (especially nowadays with Apple's soldered SSDs) the remaining pace is not enough for the scratch disk and it fails. I experience it a lot with Lightroom doing Panorama,s temp files can be hundred of Gigagbytes. Unfortunately, you can't set the scratch disk location, contrary to photoshop. It writes to the TMPDIR.
So I would like to move that TMPDIR to another external SSD. I tried the symbolic link but unfortunately, I don't have the permission to overwrite or rename the current temporary folder.
Maybe there's a way to change the way the TMPDIR is create so it does it on another drive than the boot drive, or maybe I could get the permission to modify the current one.
Thanks.
Given the fact that lots of program used that location that is often too small, it would be a major boon to get a method to put that TMPDIR on another drive.
I tried Export TMPDIR, but LR still uses the root volume one
Thanks
