Canon software is no longer compatible

Hello community members! I just switched from being an Windows user to iMac and have thus used Canon Software to view my photos. There are numerous of them and would take time to simply sync them into the new OS. I did manage to get them into the external hard drive, because I installed Mojave and the Canon software is no longer compatible. What are my options right now regarding the pictures I have?
