    Hi, as you can see on the picture below, i have an issue where my Retina MBP's SSD shows more than 260GB of free space even if the drive itself is only 250GB.
    I have checked my system, user and applications folders, which says i have roughly 80GB in use at the moment.
    I have run disk utility to check and repair the drive, unfortunately with no luck.
    Disk utility seems to think I use up to 177GB of space and remaining free space is 72GB, both of which seems to be wrong according to my own calculations.
    As i remove more and more files from my system, the drive shows just more and more free storage available.

    I have also lately had issues to empty the trash. A popup message says something like: "the file could not be removed cause *file name* is currently being used", even if the finder is the only app running.
    Just wanted to throw it out there if it might be relevant to the case.

    Currently i have no idea to fix this specifically the ssd showing more storage part.
    The empty trash part can be fixed by using terminal. But only as a short term solution.

    Thanks!

    It's the conversion between GB (gigabyte) to GiB (gibibyte). We typically count hard drive sizes as using base-10 values such as 1000, whereas computers use base-2 (binary) values such as 1024. This difference offsets the "actual" versus "perceived" values of what the software reports for the total size of your drive.

    250 GiB * 1024 MB/GB * 1024 bytes/MB = 262,144,000 bytes... and that's how you get the 262 value.


    Apologies, does "ledigt" mean "free" or "available" in Swedish? If so, that might actually be something else then.

    Yes ¨ledigt¨ means free/available space. But I think the whole thing was just a one time thing, cause now I see around 176GB of free space. So it's getting there on its own I suppose, even if its not quite there yet ;)

    Thanks for the info anyhow :)
