| Ever wondered where your notoriously rare disk space on your Apple device might be gone? | Ever wondered where your notoriously rare disk space on your Apple device might be gone? | ||
| + | If you like me come from the linux universe you might wonder - or maybe even freak out about - why the heck your admittingly small SDD is already running out of space while you can't remember installing a dozen of blockbuster video games lately. | ||
| + | ## Where to check what is stealing space | ||
| + | - At first you might want to have an overview about what ist actually on your disk. Open the MacOS Settings, there go to _General > Disk_ (maybe it's labeled differently? | ||
| + | - The coloured bar at the top of this view might show you usage of _a lot_ of disk space. | ||
| + | - A comprehensive list of data types and applications is under the recommendations regarding paper bin and iCloud. | ||
| + | - clicking the _i_-icon behind each item opens another view in which you can take a closer look into that item and maybe delete some not longer needed garbage | ||
| + | - e.g. you might check the Apps for space eaters that can take several GB of space like games, iMovie, electron based apps like chat clients etc.. | ||
| + | - or check your documents by size and remove e.g. old video files you archived on external disks before etc. | ||
| + | ## Systemdata ate my hamster ... err ... disk space | ||
| + | But still ... there will be that last item called _systemdata_ (_Systemdaten_ in german) which is huuuuuuge and won't shrink by all that deleting efforts. As you notice there' | ||
| + | In deed there' | ||
| + | ### TimeMachine Snapshots! | ||
| + | You won't get rid of all that _systemdata_ but nevertheless you can reclaim _a lot_ of it by just removing those local TimeMachine snapshots stored in it. | ||
| + | Usually you won't save your TM snapshots on your local machine, will you? If you do, you might consider plugging in a simple external disk drive and link your TimeMachine setup to it. But even then MacOS will save so many snapshots __also__ locally as there' | ||
| + | #### tmutil in the Terminal | ||
| + | Get an overview about the local stored snapshots with `tmutil listlocalsnapshots /`. Which will give you something like | ||
| + | ``` | ||
| + | Snapshots for disk /: | ||
| + | com.apple.TimeMachine.2026-03-06-202129.local | ||
| + | com.apple.TimeMachine.2026-04-05-123510.local | ||
| + | ``` | ||
| + | And as I put above that list might contain more items, maybe 5 or more. To free disk space you could delete some or even all of them by typing `tmutil deletelocalsnapshots 2026-03-06-202129` and repeat that adapted to every snapshot according to the name pattern. | ||
| + | After that you may check the disk space at the Settings again and find tenth of GB freed again. | ||
| + | |||
| + | The named article states that you also might just uncheck the _Back up Automatically_ box in the TimeMachine settings, wait some minutes and then every local snapshot will be erased and the same amount of space will be free. But I didn't try that yet. | ||
