Mac App Store: Giving up 32 bit support in favor for ARC, will existing users of 32 bit version see an update message?
问题 I'm considering dropping 32-bit support for in favor for Automatic Reference Counting (which is only supported for 64 bit binaries). I'd like to avoid these two scenarios with the Mac App Store: For a user of an old 32-bit Mac : who did purchase the previous version with 32-bit support: Will they see an update message for the app in the Mac App Store? If so, the (now 64 bit only) update would not work for him/her. who has not purchased the app before: will they be able to purchase the app
