I have OS X. I have enough available disk space. Have only used 1,5 GB of 500 GB. Notice from server. Project needs 500 MB more disk space. You currently have 0 MB available. Help.
In computing preferences there are 3 options that affect the available disk space, use at most x, use at most y% and leave at least z free.
The system will evaluate each of those and choose the most restrictive so I tend to unset 2 of them and just use the remaining 1 as this makes it clearer.
With a 500gb disk available I’d tend to say use at most 100gb and then you’re sure you’ll never run out.
