On October 7, 2019, Apple released their new OS, Catalina, which, among other improvements, now requires all programs to be written as 64bit applications and not have any dependencies on 32 bit libraries or resources. At the time of release, neither Sure Cuts a Lot 3 Pro nor Sure Cuts a Lot 4 Pro are 64bit applications and as a result have been rendered incompatible with the new OS. Since that point, however, Sure Cuts a Lot 4 Pro has received a 64 bit update, so you can redownload and reinstall the 64 bit installer here. For Sure Cuts a Lot 3 Pro, we can only recommend those with these versions upgrading their programs to Sure Cuts a Lot 5 Pro. That said, please be aware that there might be a few hiccups using this upgraded version as the developer works to assure it is fully complaint with the new OS' standards.

If you haven't updated your OS to Catalina yet, we recommend that you wait until everything settles and all patches have been published to your respective programs. Keep checking here for further updates, as we will keep this article current with all new information.


We apologize for any inconvenience that this might cause our customers, and appreciate your patience and understanding as we work with Craft Edge (Sure Cuts' developer) to get the program up and running!
