到目前为止，您的Mac支持您机器上任何应用程序的所有版本。无论是 32 位还是 64 位，您都可以在您的机器上运行一个应用程序，而不会出现任何问题。但是，这会随着 macOS 10.15 版本而改变。
将Mac更新到最新版本的 macOS 后，您将无法再运行任何使用 32 位架构的应用程序。macOS 将停止对所有 32 位应用程序的支持，现在正转向仅 64 位应用程序环境。
对于像你我这样的最终用户来说，这意味着我们需要将我们的应用程序升级到 64 位版本，否则我们将无法访问最新的 macOS 更新中的应用程序。当然，我们知道你们中没有多少人精通技术，而且您可能不知道应用程序是 32 位还是 64 位(whether an app is a 32-bit or 64-bit)。
因此，我们整理了本指南，告诉您如何在Mac上查找 32 位应用程序，并为您提供有关如何使用这些应用程序(what you can do with these apps)的建议。在本指南的最后，您将了解如何在Mac(Mac)上的最新 macOS 更新中运行您的应用程序。
使用系统报告(Use System Report)在Mac上查找 32 位应用程序列表(Apps)
System Report是(System Report)Mac上一个超酷的实用程序，可让您找到有关机器上硬件和软件元素的大量信息。虽然它的主要目的不是帮助您在Mac上查找应用程序，但它确实可以帮助您找到计算机上的所有 32 位应用程序。
以下是访问 Mac 上安装的所有 32 位应用程序列表的方法：
- 单击(Click)屏幕左上角的Apple标志，然后选择(Apple)About This Mac。在以下屏幕上，单击Mac 详细信息下方的系统报告按钮。(System Report )
- 默认情况下，您将位于报告实用程序的“硬件”选项卡中。(Hardware)单击左侧栏中的软件(Software)，然后单击应用(Applications)程序，展开应用程序列表。
- 您将看到Mac上安装的所有应用程序的列表。向右滚动(Scroll)并查看64-Bit (Intel)列。如果某个应用程序显示“否(No)”，则表示您正在查看的应用程序是 32 位应用程序。
通过这种方式，您可以轻松找出应用程序是 32 位还是 64 位。
使用活动监视器(Use Activity Monitor)在Mac上查找 32 位应用程序(Apps)
在Mac(Mac)上查找 32 位应用程序的另一种方法是使用活动监视器(Activity Monitor)工具。该工具确实可以让您确定应用程序是否为 32 位，但在您尝试查找此信息时该应用程序必须正在运行。如果应用程序未在您的Mac(Mac)上运行，您将找不到任何信息。
- 在您的Mac(Mac)上启动有问题的应用程序，但不要对其执行任何操作。从启动板打开活动监视器。(Activity Monitor)
- 右键单击(Right-click)任何列名称（CPU Time、Threads等）并选择Kind。它将在现有列的右侧添加一个新列。
- 新添加的Kind列会告诉您当前在Mac上运行的应用程序是 32 位还是 64 位。
上述两种方法都可以帮助您轻松找到Mac上可用的所有 32 位应用程序。
如何处理 32 位应用程序？
如果您发现您的某些应用程序仍然使用 32 位架构，您可能希望尽快将它们升级到 64 位版本。如果您不这样做，这些应用程序将无法在 macOS 10.15 及更高版本上运行。
大多数开发人员都知道Apple对 macOS 所做的这一更改，他们可能已经发布了 64 位版本的应用程序。有几种方法可以检查您现有的应用程序是否有适用于您的Mac的 64 位版本。
从Mac App Store更新应用程序(Apps)
如果您的 32 位应用程序是从Mac App Store下载的，则很可能开发人员已将 64 位升级推送到商店。在这种情况下，您只需(all you need to do is update the app)像往常一样更新应用程序，然后它将与较新版本的 macOS 兼容。
- 要升级您的应用程序，请在 Mac 上启动Mac App Store。
- 单击顶部的更新选项以访问更新面板。(Updates)
- 如果您的应用有可用更新，您会在它们旁边找到更新按钮。(Update)
- 单击(Click)按钮，应用程序将升级到其较新版本。
从官方网站(Official Website)获取最新(Latest)版本
您在Mac上使用的 32 位应用程序可能来自 Internet 上的网站(Internet)。在这种情况下，您可能需要查看该应用程序的官方网站，看看是否有 64 位更新可用。
只需(Simply)
前往应用程序网站并寻找更新版本的应用程序。如果可用，请下载并将其安装在您的计算机上。您现有的应用程序将更新到最新版本。
从应用程序内更新应用程序
许多应用程序允许您从应用程序菜单中获取更新。这适用于 iTunes、Chrome、AppCleaner等应用程序。
在大多数应用程序中，您可以通过单击顶部的应用程序名称并选择检查更新(Check for updates )或类似选项来获取新更新。如果您发现有可用更新，请选择它以将其安装到您的计算机上。
结论
如果您还没有这样做，如果您仍然希望这些应用程序在最新的 macOS 版本中运行，请继续将所有 32 位应用程序升级到 64 位版本。不这样做会使您的应用程序功能失调。
How To Find & Upgrade 32-Bit Apps On Your Mac
Up until now, your Mac suрpоrted all the versions of any apps on yоur machine. You could run an app whethеr it was 32-bit or 64-bit without anу isѕues on your machine. Howevеr, that changes with the macOS 10.15 version.
Once
you update your Mac to this latest version of the macOS, you’ll no
longer be able to run any apps that use a 32-bit architecture. macOS
is ceasing support for all the 32-bit apps and is now moving towards
the 64-bit-only app environment.
What that means to end-users like you and me is that we need to get our apps upgraded to the 64-bit versions or we’ll lose access to the apps in the latest macOS update. Of course, we understand that not many of you are tech-savvy and you may not know whether an app is a 32-bit or 64-bit.
Therefore, we’ve put together this guide that tells you how to find 32-bit apps on your Mac and offers you advice on what you can do with these apps. At the end of the guide, you’ll know how you can run your apps even in the latest macOS update on your Mac.
Use System Report To Find a List Of 32-Bit Apps On Mac
System Report is a super cool utility on your Mac that lets you find out lots of information about the hardware and software elements on your machine. Although its main purpose is not to help you find apps on your Mac, it does help you find all the 32-bit apps sitting on your machine.
Here’s
how to get to the list of all the 32-bit apps installed on your Mac:
- Click on the Apple logo at the top-left corner of your screen and select About This Mac. On the following screen, click on the button that says System Report beneath your Mac details.
- By default, you’ll be in the Hardware tab in the report utility. Expand the apps list by clicking on Software followed by Applications in the left sidebar.
- You’ll see a list of all the apps installed on your Mac. Scroll right and take a look at the 64-Bit (Intel) column. If it says No for an app, it means the app you’re looking at is a 32-bit app.
This
way you can easily find out whether an app is 32-bit or 64-bit.
Use Activity Monitor To Find 32-bit Apps On Mac
Another way to find 32-bit apps on your Mac is to use the Activity Monitor tool. The tool does let you find out if an app is 32-bit but the app must be running while you try to find this information. You won’t find any information if the app isn’t running on your Mac.
- Launch the app in question on your Mac but don’t do anything with it. Open Activity Monitor from the Launchpad.
- Right-click on any of the column names (CPU Time, Threads, etc) and select Kind. It’ll add a new column to the right of existing columns.
- The newly added Kind column will tell you whether the app currently running on your Mac is 32-bit or 64-bit.
Both
of the methods described above should help you easily find all the
32-bit apps available on your Mac.
What To Do With The 32-Bit Apps?
If you’ve found that some of your apps still use 32-bit architecture, you may want to upgrade them to the 64-bit versions as soon as possible. If you don’t do it, these apps won’t run on macOS 10.15 and later.
Most
developers are aware of this change that Apple has made to macOS and
they may have already released the 64-bit versions of their apps.
There are a few ways to check if your existing apps have 64-bit
versions available for your Mac.
Update The Apps From The Mac App Store
If your 32-bit apps were downloaded from the Mac App Store, it’s likely the developer has pushed a 64-bit upgrade to the store. In that case, all you need to do is update the app as you would normally, and it’ll then be compatible with the newer versions of macOS.
- To upgrade your apps, launch the Mac App Store on your Mac.
- Click on the Updates option at the top to access the update panel.
- If an update is available for your apps, you’ll find an Update button next to them.
- Click on the button and the apps will be upgraded to their newer versions.
Get The Latest Version From The Official Website
It
may be that the 32-bit app you use on your Mac came from a website on
the Internet. In that case, you may want to check out the official
website for the app to see if a 64-bit update is available.
Simply
head over to the app website and look for a newer version of the app.
If it’s available, download and install it on your machine. Your
existing app will be updated to the latest version.
Update The App From Within The App
Many
of the apps allow you to get updates from within the app menus. This
is true for apps like iTunes, Chrome, AppCleaner, among others.
In
most apps, you can get new updates by clicking on the app name at the
top and selecting Check for updates or a similar option. If
you find an update is available, select it to install it on your
machine.
Conclusion
If you haven’t already done so, go ahead and get all of your 32-bit apps upgraded to the 64-bit versions if you still want these apps to run in the latest macOS versions. Not doing so will make your apps dysfunctional.
