I updated my OS tp Catalina and Foldit no longer works.
Can you use the 64-bit version of Foldit for Macs?
The latest macOS version 10.15 (Catalina) does not support 32-bit applications. The 64-bit version of Foldit seems to be working pretty well, but the download link still defaults to the 32-bit version (it's probably about time we change this...).
64 bit is working - now I have to download all my recipes again pout!
I will now check 64 bit devprev
Devprev is also working.
Great! Glad the 64-bit version is working for you!
I think you should still be able to copy over your recipes from the previous installation. These will be in a file called "all.macro" within the old 32-bit Foldit.app (right-click on the app and select "View Package Contents", then navigate to Contents->Resources->all.macro). You can copy this all.macro file over to the corresponding location in your new 64-bit Foldit.app.
There's some more info about this on the Foldit wiki here:
I had deleted my old client. I have already retrieved the recipes from the www site.
