I am running Mavericks on a Mid 2009, 17 inch MBP. Would like to upgrade to Sierra but am an avid user of Aperture for my photo editing. I don"t want to loose that feature. Can I upgrade to Sierra and safely keep Aperture.? Update (06/24/2018) I am presently running MacBook Pro. 17" Version 10.9.5 , Memory 8 GB 1333MHz DDR3 Processor 2.8 GHz Core 2 Duo I cannot upgrade from the computer and I also no longer have the apple store working for some reason. I am running : Aperture Version 3.51 Any suggestions how to upgrade to Sierra I thought it was a free upgrade?

I’m running Sierra 10.12.6 on a 2009 Mac Pro that I flashed from a 4.1 to 5.1, I just opened my Aperture Version 3.6 with no issues.

When I answered this the first time, I didn’t have the information I now have. You’re running the near final version of Aperture Apple released before discontinuing it. Aperture 3.5 received a 10.10 stability update, so I don’t think you will have any problems in your specific case since it’s such a new version. However there’s still no guarantee it’ll run. What I would do is make a Time Machine backup of your current setup (Backup EVERYTHING) and image your hard drive so you have something to fall back on, should it not work. However, it’s not a hard requirement if you purchased 10.9 from the Mac App Store since you can purchase 10.6 for $20 and use that to access the app store and download 10.9 again. Unless your WiFi card is bad (internal) and you’re using an external one, you shouldn’t have a problem with 10.6. Apple does NOT like 3rd party adapters being able to access the store.
