Use an Older Mac: If you have a spare older Mac that is still running a version of macOS prior to Catalina, you could dedicate that machine to running legacy 32-bit apps and never update macOS, but this comes with certain security risks.A good place to start is the Mac App Store. Find and Alternative Application: If a 32-bit app hasn’t been updated by the developer, you could try to find a newer app that does the same thing.Alternately, you can check for a newer version on the Mac App Store. Look for a 64-bit App Update: If you have a favorite 32-bit app that no longer works, visit the developer’s website to see if a 64-bit version of the app is available.So, if you’re faced with crossed-out apps, here are some strategies to deal with it.
Will I Ever Be Able to Use My Crossed-Out Mac Apps Again?īecause Apple wants to push technology forward, it’s unlikely that you’ll ever be able to run 32-bit Mac software natively on new versions of macOS again.
In Catalina, Apple decided to force the issue by disallowing 32-bit software completely.
A 64-bit application can utilize dramatically more memory (allowing bigger files to load) and theoretically perform much more complex tasks than a 32-bit application.īecause Macs have supported 64-bit applications for over a decade, Apple considers 32-bit applications to be legacy software that should be upgraded to fully take advantage of the latest computing hardware. It’s difficult summarize the meaning of the terms “32-bit app” or “64-bit app” without writing a technical research paper, but if you boil it down, both terms refer to how much memory (RAM) and computing power an application can use. If you try to run one of these crossed-out apps, you will see a message warning you that it needs to be updated.īut why? And what does “32-bit application” mean anyway? If you have a 32-bit application on your Mac in Catalina or later, you will see a crossed-out symbol over its icon in Finder, Launchpad, and the Dock. Starting with macOS 10.15 Catalina (released October 2019), macOS no longer supports running 32-bit apps. The Recent Problem: Apple Stopped Supporting 32-Bit Mac Software In those cases, your best bet is to make sure you’re running the latest version of the app (check the developer’s website for updates), and you might want to try reinstalling the app from a clean source if it was damaged. There could be several reasons for this, including that the app package is damaged or invalid, the app was written for a different architecture (say, a PowerPC app on an Intel Mac), or the app is untrusted and hasn’t been given permission to run yet. If you have some other terminal emulator that supports the same focus control sequences as iTerm 2/ xterm (for the details, see doc/vitality.First: The Other Reasons an App Won’t Runįundamentally, a crossed-out application icon means that something is preventing macOS from running the application.
The plugin makes a series of Vim configurations to enable FocusLost and FocusGained autocommands for instances running under iTerm 2:
Used for the GUI or for systems where this can be done in the console (Win32).īased on searching for callers, that statement seems accurate (it is only automatically called (asynchronously) from the GUI code for various platforms and (synchronously) from the non-GUI Windows code).Īn answer to a related question (“Can I make Tmux tell Vim when its pane loses focus?”) over on Unix & Linux pointed out a new Vim plugin called Vitality. Poking around in the code revealed the function ui_focus_change whose comment says: Only for the GUI version and a few console versions where this can be detected.
