You are watching the sunset era. One after another, companies refuse to support the 32-bit architecture and only migrate to 64-bit applications. Follow for Apple.
This should make it easier for developers, many of whom now support both options. They will be able to concentrate on one architecture and make software on its basis more simple and stable.
We strongly recommend that you look for alternatives for 32-bit applications on your Mac today. In this material, let’s talk about this in more detail.
Apple refuses 32-bit applications in 2 steps
As early as the summer of 2017, Apple officially announced that it plans to abandon 32-bit software. In this case, macOS High Sierra will be the last OS on which it will work.
Of course, the company notified the developers that it’s time for them to stop beating the buckets and get a little podnapryachsya.
“New programs in the Mac App Store must support the 64-bit architecture from January 2018, updates and existing applications – from June 2018”
And the other day the company reminded developers about the time of C. She specified that macOS 10.13.4 will start to notify users that soon with 32-bit software it will be possible to say goodbye.
When these applications are launched, they will receive the appropriate notification:
“This application is not optimized for Mac”
Now the OS scolds, but it launches such programs and games. But in the future will stop doing it.
Apple will abandon 32-bit applications in 2 steps: first it will not launch it in the Mac App Store, and then it will prohibit running on current versions of macOS.
Than 32-bit programs differ from 64-bit programs
Speaking purely technically, the difference between 32-bit and 64-bit architectures lies in the length of numbers with which software and hardware solutions can work. The second must deal with large amounts of information faster.
32-bit applications can use no more than 4 GB of RAM, but 64-bit similar restrictions do not exist. This is especially noticeable when it comes to the use of media content from the network via HTML5.
Simplify, 32-bit applications work better on 32-bit systems, and 64-bit applications work better on 64-bit systems. Since modern macOS has long since entered exactly in the second channel, with the echoes of the former, one must resolutely say goodbye.
This is decided to do in Apple. Therefore, at first macOS will sometimes remind you of compatibility issues, then it will start doing it with more intensity, and in the end it will simply stop running the inappropriate software. It’s time for such applications to look for a replacement.
How to find 32-bit applications on Mac and remove
Find 32-bit applications among the installed on your Mac is very simple:
Step 1. Open the macOS system menu by clicking on the Apple logo in the upper left corner of the screen.
Step 2. Go to “About This Mac”.
Step 3. Launch the “System Report …” menu.
Step 4. Find the “Programs” section in the menu on the left.
Step 5. In the last column on the right, “64 bits (Intel)”, find the value “No”.
Step 6. Remember all the applications that you need to replace.
Step 7. Find the alternative and delete.
For example, it turned out that the refusal to support 32-bit architecture would catch me from the printers. At the university, where I sometimes lecture, I have an old Canon LBP6020. Its drivers do not support 64 bits.
In theory, developers should rewrite the drivers for the device. They released updates for new macOS a week or two after the release of the official OS versions. But you can not be 100% sure of that.
Moreover, there is a sea of software, the development of which has already been abandoned, so I definitely have to find an alternative for them . And I’m sure you have a similar situation.
What it takes to stay without support 32 bits
I return to work with the printer. I really really often have to print materials on it for students, and I just can not give it up.
In this case, I will simply not have to update further macOS High Sierra, on which I am now. Nevertheless, it will be easier for me to buy a new printer at my own expense, even for public use.
In general, on macOS, the situation with the rejection of 32-bit applications is less acute than on iOS. With iOS 11, this software does not work, and it almost does not remain in the App Store, without which you can install neither programs nor games.
It turns out, even if you stay on iOS 10, you will lose access to many applications. But in the case of macOS High Sierra, you can simply install distributions from alternative sourcesinstead of the Mac App Store.
However, this is no reason not to abandon 32-bit applications. I’m sure that until now have not translated into 64 bits only frankly flawed software. This is exactly what you need to look for a replacement.
How do you feel about the rejection of 32-bit software?
I have a dual attitude towards Apple’s refusal from 32-bit programs and games. On the one hand, it’s a ballast that only pulls the system down. On the other hand, the company simply forbids me to use a conventional printer – that’s horror.
Your opinions are divided similarly. There are positive:
“Well done – throw out of the system too much. Not that the Windows, where the garbage from the time of DOS. Not to mention the dibilnoy system with two Program Files folders and a dozen curves of HiDPI support methods of which none really works. “
There are negative:
“Well, why throw out support for 32 bit applications? Little whether any old application can come in handy, it’s a computer, maybe anything. It’s good that Microsoft does not suffer from such delirium with Windows. “
And where is the truth? I think she’s somewhere in the middle. I think Apple really should push the developers to the transition to 64 bits, but it has no right to restrict users.
