Improving performance on an older slower iMac: How?!!



  • Rick Sammartino Community moderator

    I don't use a mac but the first suggestion would be to check the On1 specs and see if there is something you can update.

  • Tom Murray

    To start, turn off every other application.

    Is there  room for more memory in your iMac.

    Check out the recommended system requirements.

    I'm running 2019 beta also on an iMac 2011 3.1 Ghz with 1GB AMD Radeon video card and in edit mode moving from one image to next takes 1 second, I run 12GB RAM as this is easy to upgrade yourself but I also removed the DVD drive and replaced it with a second SSD drive which is the one I use to do my photo editing on. I paid someone £120 to fit and configure the SSD which makes a massive difference.

    I would suggest a RAM Upgrade first as this is cheap and you can do it yourself.

    Yes. My ram is maxed out.

    No I’m not running any other memory intensive apps or processes concurrently.

    Im looking for settings within the app itself that would speed it up.

    And no, I don’t want to use “Fast Raw Preview” setting. I need to be able to see exactly what my adjusted images look like as I work on them. That is the WHOLE point of using an app of this type.

    The only settings I know of are under preferences.

    You don't mention how your specs compare to the recommended system requirements.
