Concerning Mac software, it's tough for both developers and users, since Apple upgrades their OS pretty much each year in the fall. And quite often when users update their OS, is may cause some incompatibility for Chess King (and quite a few other Mac games), and it forces us to get into urgent fixing mode, which sometimes is quite costly. For this reason, we ask for your understanding, and in exchange we keep the upgrade price very low, and when you take into consideration you also get a 3-month pack of 90 courses Chess King Learn, it's basically free.
You need this upgrade if your previous version ran on Mac OS X 10.13 High Sierra or OS 10.14 Mojave or previous and you upgraded to either 10.15 Catalina or 11 Big Sur or OS 12 Monterey or OS 13 Ventura or OS 14 Sonoma. Apple changed the OS with Catalina which broke compatibility with all 32-bit apps, which forced us to make a new version. This is the same product as the Chess King 24 for Mac, simply you get a discount for being a prior Chess King user. To qualify for this offer, you need to provide your previous Chess King serial number. If you have a Chess King 23 or prior, it's worth upgrading to Chess King 24 to get the GigaKing database with now 8 million games, update GigaTree and some more program improvements.
