Tech Tip – Apple will soon be taking the next step in their transition to all 64-bit Apps. When macOS 10.13.4 comes out, users will get a one-time alert when they open any 32-bit Apps. Users will be cautioned in that alert that the 32-bit Apps will be blocked at some point in the near future when Apple completes the transition to an all 64-bit App space.
Until the transition is complete (on a date yet to be announced by Apple) users can still use the 32-bit Apps. However, if you are using a 32-bit App as part of your daily workflow, you need to be prepared to replace it if the developer does not update it.
So how do you tell if an App is 32-bit or 64-bit? This is easy. go the Apple icon in the top left of the menu bar and click on “About this Mac”. In the “Overview” category, click on “System Report”. Scroll down to “Software: Applications”. It may take a few seconds to populate the window. At the far right side, there is a column labeled “64-bit (Intel)”. Any Apps with a “No” in this column is a 32-bit App. To make it easier to find the Apps you are looking for, click on the column header. That will sort the entries so that all the Apps with a “No” will be at the top of the list.
As you can see in the image above, my MacBook currently as six 32-bit Apps installed. Now I either need to find replacement Apps, hope the respective developers will upgrade their Apps, or take some action and contact the developers asking if they will soon release an update.
