I have Aperture 1 on my 2007 MBP.  It runs beautifully and doesn't slow my computer (it's an old laptop, everything is a little slow).  I'm concerned about allot of feedback saying Aperture 3 is slow and bogs down allot of RAM??? I have a new IMAC, and don't want to slow it down right out of the box, but I'm a semi-pro photographer and have really enjoyed Aperture in the past.  Is it really going to change the performance of my new IMAC?

Aperture 3, OS X Mountain Lion (10.8.3)

    How much RAM do you have, and how large are your original image files?

    Do you have really large raw files, 60 megapixel or more?


    If you are using Aperture 3 sensibly - not running too many Applications concurrently that also need much RAM and don't work with gigantic scans - Aperture 3 will be o.k.. You should at least have 4GB RAM.

    Aperture 3 will make use of the available RAM to speed up the processing. My oldest MBP only has 4GB RAM, but Aperture works very well, as long as do not open iMovie, GarageBand, and Safari concurrently.


    All cases I have seen with Aperture 3 being slow, were caused by problems with the initial setup:

    • Upgrading the library will take a long time, if the library is large (reprocessing the raw, recreating thumbs and previews, indexing faces, ...)
    • Aperture can be slow, if the library is corrupted and needs repairing.
    • Aperture can appear to be slow, if corrupted media have been imported (incompatible videos or something)
    • Aperture will be slow, if the Aperture library or the referenced master files are on a network drive and the access to the library is slow or the system drive does not have enough free disk space.





    Added: Before upgrading have a look at the release notes:


    Scroll down to the bottom of the page, where it says "Additional Information - A note on upgrading your Aperture library". That part is really important. Don't upgrade without repairing your Aperture libraries using your current Aperture version before the upgrade, and backup the libraries and the current Aperture version, so that you have an option to revert to your current setup in case something should go wrong.

    You are welcome, glad to help


    I have a new IMAC,

    Aperture will profit from any RAM you add. I wrote 4GB minimum, thinking of your older mac, but if you can upgrade the RAM 8GB or 16GB, it ill not be wasted.
