Hello, I'm having a strange issue for a while now and I have no clue how to fix it. Each time I try to "Save as" a file from any application (Word, Excel, Photoshop, Chrome), I have to wait a few seconds (generally around 5s) in order to see the Finder popup appear, letting me choose where in my disk I wish to save the file. However, when I clic directly on the Finder icon in the shortcuts bar, it appears immediatly. This is even more disturbing since the computer is quite fast and has no other kind of lag. With an SSD disk, I'd expect an extreme fluidity with this kind of action! Anyone also has this problem? Thanks! Diagnostic : - I have no external USB drive of any kind plugged. - I'm only linked to my Internet network, I don't share any file et I face the problem whatever network I connect to. - I run on OS Yosemite (10.10.5) with i7 proc, 8GB RAM and 250GB SSD Disk.
