Windows 32 bit or 64 bit mac os

Совместимость 32-разрядных приложений с ОС macOS High Sierra 10.13.4 и более поздних версий

Узнайте о переходе на 64-разрядную технологию и его влиянии на 32-разрядные приложения.

Компания Apple начала переход на 64-разрядное оборудование и программное обеспечение более десяти лет назад. Все современные модели компьютеров Mac теперь оснащаются мощными 64-разрядными процессорами, способными выполнять современные 64-разрядные приложения. Эти приложения поддерживают существенно больше памяти, повышают производительность системы и используют преимущества исключительных технологий Mac.

Компания Apple проработала с разработчиками перенос приложений и в 2018 г. уведомила их, что macOS Mojave будет последней версией macOS, поддерживающей 32-разрядные приложения. Начиная с macOS Catalina, 32-разрядные приложения больше не совместимы с macOS.

32-Bit vs. 64-Bit and Why It Matters

Chances are high that you’re running a 64-bit/x64 operating system, application, or CPU—and you don’t even know it.

With macOS Catalina dropping support for 32-bit, some users may find themselves without their favorite applications. Now, macOS will warn users prior to upgrading to macOS Catalina and showcase the incompatibility:

In order to continue using your favorite 32-bit applications on macOS Catalina, the software developers will need to update the software to support 64-bit. If the software developer chooses not to do this, users can utilize a virtual machine with Parallels Desktop to run their favorite applications on their Mac.

What is a bit?

By means of Lifewire’s definition, a bit is shorthand for binary digit. In laymen’s terms, this is where you see units of measurements regarding 1s and 0s and can apply to computer networking or memory. Sometimes you’ll see the formatting as “32-bit” or “x32.” These two formats represent the same thing.

32-bit and 64-bit operating systems

The 32-bit processor was the most popular processor used by computers until the early 1990s. Both Intel Pentium and AMD processors were 32-bit, which means Microsoft’s Windows 95, 98, and XP are all 32-bit operating systems. However, a slight shift occurred in 2003 when Microsoft released a 64-bit version of Windows, and then in 2005 shifted the internal processor to a 64-bit AMD processor.

Microsoft Windows utilizing a more powerful processor in combination with a more powerful operating system unlocked a lot of potential with improved security, better game performance, and the ability to allocate more memory as needed. Why does this matter? Every personal computer (whether a Mac® or PC) has a 32-bit OS or 64-bit OS, and this dictates the user experience. The OS and the software used is the underlying foundation for our productivity.

Difference between 32-bit and 64-bit CPUs

Simply put, a 64-bit processor is more capable than a 32-bit processor because it can handle more data in any given moment.

The most popular consumer reference to a x64 processor in CPUs or hardware is the Nintendo 64. Hence, the name. Personally, I always thought this was due to 64 games being released with the Nintendo 64 (haha). Nope, it’s due to the processor. Additionally, through a popular HowStuffWorks article, I’ve learned that this specific processor was a customized chip system that was named the 64-bit R4300i “Reality Engine.” (Insert an oooh and an ahhhhh here.)

What’s the difference between 32-bit and 64-bit software?

HowToGeek outlined a very helpful article: “Why are most programs still 32-bit on a 64-bit version of Windows.” It provides useful information about why users should care about the difference and how it effects their productivity.

The biggest and most simple way to answer what the difference is between 32x and 64x software is that the 64x version will be more secure and reliable.

How to check if a macOS application is 32-bit or 64-bit

If you’re on macOS® Mojave, it’s quite easy to see if any application on your Mac is either 32- or 64-bit. Follow this pathway:

Apple menu > About This Mac > System Report

From the System Report, scroll to Software > Applications> Select your desired Application

Depending on the applications on your Mac, you may see mostly 64-bit, some 32-bit, or all 32-bit. This is entirely dependent on your personal setup.

How to run older 32-bit operating systems and applications on your Mac

Running older 32-bit operating systems or software on your Mac is quick and easy. With Parallels Desktop® for Mac, you can virtualize any 32-bit operating system in a virtual machine and run your needed application. 32-bit operating systems could be either macOS or Windows. For example, this is what a 32-bit macOS virtual machine looks like in Parallels Desktop:

Running a macOS virtual machine on the macOS with Parallels Desktop may seem a bit redundant, but it is absolutely necessary for users who need older 32-bit operating systems or applications. It’s also necessary for developers to code, test, and deploy without buying secondary machines.

Downloading a free trial of Parallels Desktop is easy! Simply download the .dmg, create a new virtual machine with the operating system needed, and run the application to get started.

How to check if your Mac’s software is 32- or 64-bit

MacOS 10.14 Mojave, the version of the Mac operating system before the new macOS Catalina, is the last version that supports 32-bit software. With Catalina, only 64-bit software will be supported.

Catalina is here and if you decide to upgrade to the new macOS, you need to do a bit more than usual to prepare your Mac. You need to make sure your apps are 64-bit versions. If your app is a 32-bit version, it will not work.

Apple actually started to warn people about the change with macOS 10.13 High Sierra. If you launch a 32-bit app in High Sierra, an alert pops up to tell you that your app needs to be updated. The alert appears only once in High Sierra, and in Mojave, it appears every 30 days.

If you can’t recall whether an app needs to be upgraded or not, there are a couple of ways to find out besides the launch alert. Here’s how.

Use Go64 to find 32-bit apps on your Mac

St. Claire Software has a teriffic app called Go64 (free, donations accepted) that scans the software on your Mac and tells you whether the each app is 64-bit or not. Go64 is fast and it also provides web links to the app developer’s website, so you can go see if the developer has an update. Learn more about Go64.

Go64 provides a more detailed look at which apps need updated or deleted before installing macOS Catalina.

Find 32-bit apps on your Mac through System Report

1. In the Finder, click on the Apple menu and select About This Mac.

2. In the Overview section, click on the System Report button.

3. In the left column of the System Report, scroll down to the Software section. Then select Applications.

4. The section on the right may go blank for a moment. This is because your Mac is compiling a list of software on your Mac. When the window appears, it will have two sections. The top section is the list of software. The bottom section shows more details about an item if you click on it in the list.

If you click and hold the dot in the divider between the two sections, you can resize the window so you can see more of the list, or more of the details.

5. In the list, there is a column called “64-Bit (Intel)” that is located to the far right of the top row. If you don’t see it, try expanding the window by clicking and dragging the right edge, or you can scroll the window to the right. Once you see the 64-bit (Intel) column, you can click, hold, and drag it to the left to reposition it closer to the app names.

6. Now you can see if a particular app on you Mac is 64-bit or not. If it’s listed as Yes, it’s 64-bit. If it’s No, it’s a 32-bit app, and you need to upgrade it before using macOS 10.15.

Find 32-bit apps on your Mac through Activity Monitor

There’s an app called Activity Monitor that you can use to identify if an app is 32-bit or 64-bit. But it only works when an app is launched and running.

1. Launch Activity Monitor, which is in Applications > Utilities.

2. In the CPU section, you see a list of apps running on your Mac. Right click the top row of categories. In the pop-up list that appears, select Kind.

3. At the right end of the top row, a new column called “Kind” should appear. You can click, hold and drag it to a new location if you wish. Like, say, next to the application names.

4. The Kind row will tell you if a running app is 32-bit or 64-bit. You’ll need to upgrade 32-bit apps before using macOS 10.15.

How to upgrade 32-bit apps to 64-bit

Once you’ve identified a 32-bit app, you need to upgrade it, or it will not work in macOS 10.15. Upgrading it usually involves downloading an update created by the developer.

If you bought the app in Apple’s App Store, check it for any updates. Click Updates in the left column of the App Store app. Available updates appear in the larger window on the right.

Check the developer’s website for an update.

Some apps can look for updates within the app. Launch the app, and look for “Check for Updates” or something similar in the Help menu, or in the menu named after the app (for example, the Safari menu in Safari), or in the app’s preferences.
