Strangely though, if you already have the game installed, you should be fine:Įxisting players with League of Legends on their Macs will not have any problems or changes with League of Legends when Catalina rolls out. So in the meantime, if you know someone who is interested in installing League of Legends, they should do so before Catalina debuts in October OR not update their macOS to Catalina until they do. However, in the case of League of Legends for Mac (LoL), the problem is vague and unclear:Īt this time and with what we know, people will not be able to install League of Legends on their Mac devices on Catalina. In most cases, the root cause is straightforward: A game is still 32-bit and hence will stop working on Catalina. The list of games suffering from Catalina’s mandatory transition to 64-bit continues to grow.
