Late 2015 iMac ( 27inch).
I own a late 2015 27inch iMac with 500gb fusion drive incorporating a24gb ssd. The SSD has only 1.5 GB occupied with applications. The rest of the SSD is occupied with the operating system and library’s leaving only 1.4gb free. I am unable to download photos etc as thexerror message is ‘ not enough space’. I have 400gb free on the fusion drive. Does one have to download to the SSD? Surely not. Any help would be greatly appreciated.
