Apple confirmed yesterday that macOS Mojave is the last release from the company to support 32-bit apps on the desktop.
Cupertino is Phasing Out 32-bit Apps Completely - Mojave Sets Another Foot in Stone for 64-bit Only Apps
Apple dropped the hammer against 32-bit apps with the release of iOS 11 by supporting only 64-bit apps and devices. Though Apple shoved in warnings in iOS 10 suggesting that the end is coming for 32-bit apps, but it was a clear sign that Apple would carry over such a movement to its desktop operating platform, macOS.
During Apple's WWDC 2018 opening keynote yesterday where they announced macOS Mojave, the company flashed a nice big slide in the backdrop stating that "Mojave is the last macOS release to support 32-bit apps." To clarify, even if you download Mojave later this year, you will still get warnings. But obviously, with subsequent releases of macOS, those warnings will turn into a harsh reality which every developer has to accept.
If you are interested in knowing which app you currently have installed is 32-bit or 64-bit, just follow the steps outlined below.
- Click on the Apple logo in the menu bar.
- Now click on About this Mac.
- Under the Overview tab, click on System Report.
- Select Applications from the left hand side pane.
- On the top right you'll see a scrollable list of your apps with a column called "64-Bit (Intel)". If it says 'Yes' then it means that the app is 64-bit, if 'No' then it's otherwise.
Regular apps can be updated to support 64-bit systems in no time, if a developer wishes to. But if you heavily rely on something that hasn't been updated in a long, long time, then it's best to start looking for good alternatives right now before you are greeted with a bombshell of disappointment later.
