    My 2016 MBA has no space on the 128 GB hard drive and it looks to be nearly completely full of system files. I have Time Machine set up at home on my Airport, but I’m often away from home for months at a time. I’ve researched this a bit and one possibility is that when I’m away from home, the mba is taking TM snapshots which aren’t getting deleted properly. I’d appreciate any advice on how to recover that hard drive space. On High Sierra, btw, which is when this started.

    Here’s what I’ve done so far:
    1. Full backup to time machine on airport.
    2. Optimized everything in Storage Mgmt.
    3. Deleted all old files.
    4. Tried to turn off time machine in Terminal, but don’t think I did anything.

    Run this command in Terminal and it will delete all the local snapshots Time Machine keeps.

    There should manage themselves and delete after a couple days though.

    tmutil  listlocalsnapshotdates / |grep 20|while read f; do tmutil deletelocalsnapshots $f; done
