Aperture 3.5 on OS X 10.9

Sigh, me too. Formatted an external FW800 drive GUID and Mac OS Extended (Journaled) and I cannot get Aperture to use it as a vault. Aperture freezes part way through updating and shows as "Not Responding" in Activity Monitor. I have to force quit Aperture. On one occasion it froze my whole computer and I had to do a hard shut down by holding the power button on my Mac Pro. Crap.

That happened to me so many times, that I quit trying to do Vaults....which is BAD!

Need a solution soon!

My backups are a regular Time Machine backup plus clones of the disks with the Aperture libraries instead of vaults. Updating the clones does not take much longer than updating a vault.

So many problems with Aperture. When my main "work" programme freezes my Mac Pro I feel like I have a 40 lb. iPad to surf the web and send email. Before it would "hide" any second or third revisions of a picture I edited in Photoshop. I had downloaded a trial of Lightroom when they finally fixed that with the latest revision. Now this. Erratic imports, crashed computers when setting up Vaults etc. etc.

I want to spend my time taking photographs, not learning new software, so I am not anxious to change to Adobe.

I have loved Macs since I sent back a Windows XP machine in late 2001 and I have used Aperture since its very first iteration but this is really trying my patience.

I'm in the same position as you. MBP 8Gb RAM, Mavericks, freezes halfway through creating Vault. External FW HDs, OSX Extended Journaled etc.
I have looked at Acticity Monitor, and although I have no other programs running, and over 94% of my CPU is idle, the Memory Panel tells me that I'm using 7.84Gb of my RAM. Where the **** can it be going?

Maybe related... I've also had horrendous troubles in Mavericks trying to ditch large numbers of image files in the Trash. Once again, it chunders to a halt and eventually freezes the machine. Seems to be a root problem with Mavericks with memory management, exacerbated by hefty programs like Aperture.

Like others, I'm loathe to turn to Adobe, but as a working photographer, I can't work with this.

Same with mine just installed Aperture 3.5.1. Can't vault on my freenas.org filer via afp with same symptoms.

Apple has to understand that NAS filers is the common option today to store/vault data. I can't format it in MacOS HSF Journal except I do iscsi - not good, causing extra headache. After payng 2000 rub I feel lie the one sent to stoneage.

It's highly like the file system on the NAS doesn't support the file names used by Aperture in its library.

You can create a sparse image on the NAS, mount that on your computer, and back up to it if you want.
