Constant Crashing, Affinity Photo on Mac

Recommended Posts


I use Affinity Photo on my MacBook Pro, Retina running MacOS Mojave.
I'm having problems with affinity randomly crashing, sometimes I can even start it, it'll crash right away.

I can't really identify an origin,… sometimes it crashes when I'm painting fast, sometimes even when I was looking at the painting/zooming out.

My ram should be fine, I have around 20GB+ storage space and I never downloaded brushes or any other plugin.
Already tried to reinstall and restart my Mac.

I never had that before, just in the last two months, of the one year+ I'm working with Affinity.

I hope someone knows more, or at least can tell me if Affinity Photo has Autosave (can't find it anywhere), so at least I can breathe.

Thanks in advance,

Hi ViDeez,

Welcome to the forums :)

Sorry to hear you're having trouble!

Firstly, could you please open Affinity Photo>Preferences>Performance and provide a screenshot of your settings here for me?

Secondly, I'd like to request a copy of your latest crash report. Please go to Applications > Utilities and open the Console app. Crash Reports from our apps can be found in the User Reports section. You can Right Click the required Crash Report and select Reveal in Finder.

Thirdly, resetting your app back to its default settings may help reduce the crashing, however this is a somewhat destructive option (as you lose all custom brushes etc) so please only try this if you are happy with this.

You can reset your app back to its default settings by holding down the CTRL key while launching the app. When the Clear User Data window appears, click Select All and then Clear. The app will now open.
Be aware that resetting your app back to its default settings will lose any custom settings such as keyboard shortcuts and brushes etc. To backup such settings before resetting the app, please watch our Affinity - Exporting User Settings and Keyboard Shortcuts video. https://player.vimeo.com/video/189596577/
