    Hi folks, somehow I do not manage to get rid of the following problem:

    Unfortunately I decided to buy myself a model with flashdrive hard disk.
    Somehow it really starts to annoy me: I am running most of my system from the 125GB flash drive, only Apple loops from an external 64 GB SD card I have permanently inserted in the SD card slot. What ever I delete from the flash drive, the space gets "eaten" by something over a period of time. After I removed something like 13 GB, it takes a few hours before the system tells me that I am running low on disk space. Usually that is, when there is around 1GB left. After a restart I make it up to around 4 GB again, but they disappear quickly to somewhere...
    I have been in assorted forums, emptied my caches, made a time machine backup and am using programs like Daisy Disk, Disk Doctor and you name it to keep it all down, but ... hey, it is supposed to be a "Mac"... I somehow expect some peace to work... Any friendly soul, that can relief my pain?

    (2,6GHz 13'MBP, retina, 8GB memory, OSX 10.10.3)

    The system makes cache files on the boot drive, it is normal and is expected to take up space. 4 GB is waaay to little space for the system to run optimally - It should be around 15GB in my experience.

    Would you have any apps that generate log files/temp file/etc?

    Are you deleting files and actually seeing disk space released in disk utility. And odd feature I noticed on massive deletions is my system drive would not register the free space I thought I would have. The easy fix to this is turn off time machine for a little while.

    Forget the technical reason for why this works when I saw the trick posted somewhere. I do know in my case it works.
