MacOS 10.15 Catalina : How to Find 32 Bit Apps : Since MacOS 10.13 Apple have been warning users that 32 Bit Apps are on the way out. Well, with the release of MacOS 10.15 Catalina that time is now.
So before you upgrade you really should test what is going to stop working. At least then you can make the decision to go ahead with the upgrade or wait a while and see if the App Developer releases a 64 Bit update. Although to be fair – they have had enough warning so probably should have already done so! Don’t give up though, some lazy developers are still releasing updates.
Personally I have upgraded my MacBook Pro and not my iMac. I’m impressed with Catalina and would love to upgrade my iMac too however I can’t bear to loose Cannon Fodder, Theme Park, Sim City 4 and a few other classic games. Everything else that hasn’t bothered with updating – well I’m happy enough to move on without them, no doubt better alternatives are already out there.
Two programs of note that are a potential sticking point for many are :
1. Microsoft Office 2011 – this is not compatible and upgrading to Catalina will force you onto the Office 365 Subscription model.
2. Aperture : Apple’s own image software will no longer work with MacOS Catalina.
