Initial Aperture 3 release triggers severe memory leaks

updated 01:15 pm EST, Tue February 16, 2010

Virtual memory eventually renders drives unusable

Serious memory leaks are being caused by the newly-released Aperture 3, complaints on Apple's support forums suggest. Affected users note that virtual memory can spiral out of control, to the point that it can consume all of the free space on a Mac's hard drive. This can result in a Mac becoming unusable, either extremely slow or ultimately hanging.

The precise origins of the leaks are uncertain, as several different actions have been linked to the issue. For some people leaks may begin by trying to import an older photo library; others claim the problem is tied to enabling the new Faces feature. The program may even start leaking immediately after launch, or not at all, which may raise the question of whether outside circumstances are involved.

Apple has yet to publicly confirm any leaks or mention a timeline for a fix. Such a policy is standard for the company however, which regularly remains quiet on troubleshooting issues until patches become available. A temporary remedy is said to involve forcing Aperture to operate in 32-bit mode, capping the amount of memory it can access.

    neither my roommate or I has had any problems. however I'm on leopard and he's on Snow in 32 so maybe that's the trick. and neither of us has a particularly large library. that likely helps. We'll be watching for any issues regardless

    Count me in

    Has been locking up my computer. I've been blaming Safari. Also seems to gobble VRAM. Now I know why.

    I knew about this...

    As soon as I installed Aperture 3.0 I rebooted. Launched it and it converted my library. After it converted my 8 core 2.66 6gb mac pro seemed very sluggish. So I rebooted again. Launched Aperture 3.0 only... and used it a bit... only to find my computer was sluggish again. If it's bringing my 8 core 2.66 Mac Pro to it's knees, I can't imagine what it's doing to MBPs and iMacs. I'm done with Aperture... it's Lightroom from here on out.

    It's the flash module...

    The issue isn't with Aperture, it's with the flash module of Aperture! ;-)

    @emig647 - Seriously, Lightroom... Like Adobe is any better at programming on the Mac!? If I recall Lightroom had some serious issues with it was first released and it took adobe a while to fix it.

    I love the, "one issue and I'm not using XXXX." statements!! Hum, lets see Aperture $200 and Lightroom $300, now why would Lightroom only be $300 because Photoshop is $700/$1000... COMPETITION YOU IDIOTS!!!!!!! Look at Flash and Illustrator, since Macromedia was purchase by Adobe, Freehand is GONE and Illustrator hasn't had any major competition and the program reflects this, Flash has seem some advancements but nothing more then the addition of Video to truly advance flash. Look at In-Design now that is a program that has advanced, why, because of Quark Xpress it is the competition that keeps these companies on their toes. Let say it all together now, "Windows 7 is around because of Mac OS X!"

    Hey emig647, please do us a favor and post your Aperture for sale, so I can buy it for $100 and when Apple releases 3.0.1, I will have a much better integrated Mac OS experience.

    Yeah, it's slow

    I'm on a 24" iMac/2.93 Core 2 Duo (early 2009) with 4GB of RAM and I can attest that Aperture 3 *is* dog slow. Things that used to take millionths of a second will often tie my machine up for 25-30 seconds. I'm sure this is the sort of thing that will get sorted out shortly in an update, but until then importing and editing are certainly going to be painful.
