    Installed sierra this morning and couldn't believe that I had about 60gb free space after the installation - before it was about 30gb free. MacBook Air 2012 128GB.

    I first thought maybe this has do to with the cloud outsourcing of languages, fonts etc.

    I didn't go for the cloud optimization if disk space gets cramped.

    Under "about this mac" where you can see your drives, it shows a block as "erasable" (actually don't know what it says in english, I'm from Germany) which is about 25GB. "Löschbar" in german.

    Going to disk utility there is also an erasable-block and underneath it says free space only 35GB.

    What i want to point out is that the free disk space of my macintosh hd on my desktop is not the actual free disk space which I find very annoying. I don't want to outsource everything to iCloud and get rid off my data redundancy.

    Check out the screenshot. [​IMG]

    What do you think about this? Am I missing something?

    Total BS!

    I have a MacBook Air 2015 128GB and updated to Sierra two night ago. I did not see any changes in the amount of hard drive I had available. Out of curiosity I did check that right before the upgrade. My free amount of iCloud Storage was the same +/- a few Mb.

    Interesting... but the free amount of iCloud storage didn't change on my mac either - that's not the problem.

    "Löschbar" is called purgeable in English in that case. I think the purgeable storage space will be freed up in case you fall short of overall storage, meaning macOS will only delete those files if this occurs. Could be photos which are stored locally and are saved in iCloud in original resolution as well, cache files, log files etc.

    Rok73 has it, basically. Per "Files marked as purgeable can always be downloaded again on demand." This would include anything duplicated on iCloud, and caches.

    Okay that starts to make sense, my iCloud Photo Library on disk is about 27GB and I have optimized storage turned on. So it could in case of low storage shrink the library resulting in the gain of storage it is showing me now.
