my /tmp/ folder is to small, even though there is enough space

I need TEMPDIR space for a software backup. I tried to use other volumes and clean space, but nothing seems to work.

so I re-installed my whole system, the backup worked once again, but now I have >50GB free on my (only) disk, but still /tmp/ seems to be stuck, no matter how much space I clean up.

I saw that there are possibilities to unmount the directory and then mount it with different sizes in Unix systems, but it does not work with Mac.

this is the /tmp/ space I currently get:

https://discussions.apple.com/content/attachment/e169c196-463e-4e8b-89ab-e8e0cc9cf32e

uninstalling applications, deleting files and everything (yes, I restarted the system), deleting /System/Library/Caches/com.apple.coresymbolicationd does not work at all.

any Mac version of the upper mentioned mounting strategy or anything else I could try to resize this section?

What software backup...?

A SafeBoot will clear system cache files: SafeBoot https://support.apple.com/en-us/HT201262

reboot as normal.

I have never had to jump hoops to backup...

out of curiosity by comparison:

There is no separate space allocation for /tmp. That is just the free space on your hard drive. You will get the same values with:

df /

Although I would recommend:

df -H /

to give you human-readable content.

According to your data, you only have a 120 GB hard drive with 12 GB free. It is unlikely that you will be able to make much more storage available.

The operating system will manage your storage and try to keep itself from crashing. But you aren't ever going to get a big chunk free again. I'm impressed that you got it to 34 GB.
