If macOS no longer supports 32-bit programs, you can try the following methods: 1. Use a virtual machine (such as Parallels Desktop or VMware Fusion to install the old version of macOS to run 32-bit programs. You need to prepare a Mac, virtual machine software and legacy system image with good performance; 2. Find a 64-bit updated version of the software or use alternative software, such as using GIMP or Affinity Photo to replace the old version of Photoshop; 3. Install Windows through Boot Camp on Intel Mac to run 32-bit applications, but the operation is complicated and the driver may be incompatible; 4. If the software is no longer maintained, you can only keep the old Mac running. Each method has its own advantages and disadvantages, and appropriate solutions should be selected based on technical capabilities, equipment type and usage needs.
Apple's macOS has gradually moved to a 64-bit architecture in recent years. Since a certain version, the system no longer supports 32-bit applications natively. If you still have some old software, old tools or classic games that can only run in 32-bit environments, you will find that they cannot be opened on the latest macOS at all. What should I do? In fact, there are still several ways to try.
1. Run legacy macOS using a virtual machine
This is one of the most commonly used and reliable methods at present. Through a virtual machine (such as Parallels Desktop or VMware Fusion), you can install an older version of macOS (such as High Sierra or earlier) in the current macOS system, and then run a 32-bit program in this "virtual computer".
- You need to prepare :
- A Mac with good performance (more than 8GB memory)
- Virtual machine software (Parallels is more suitable for beginners)
- A compatible old macOS image file
- Operation suggestions :
- Remember to select "Customer" as macOS during installation and allocate enough hard disk space and memory
- After the installation is completed, just copy the old program you want to run in.
Note: Although this method is effective, it requires a certain operating basis and occupies a lot of system resources.
2. Find alternative software or newer versions
The reason why some old programs are still using 32 bits is because they have not been updated. You can first go to the official website or developer page to see if there is a 64-bit version launched. If it has not been updated, you can also find out if there are any modern alternatives with similar functions.
For example:
In the past, some people used the 32-bit old version of Adobe Photoshop CS5, but now they have basically been upgraded to the 64-bit version of Creative Cloud. If you don't have a budget to buy new software, you can also try open source or low-priced alternatives such as GIMP and Affinity Photo.
3. Install Windows using Boot Camp (Intel Mac only)
If your Mac is an Intel chip instead of Apple Silicon (M1/M2 series), you can also consider installing Windows with Boot Camp and then running these 32-bit applications under Windows. However, this method has several limitations:
- Only available for Intel Mac
- Requires additional partition to install Windows, which is a bit complicated
- Some drivers may be imperfect, especially new Macs
So if you don’t have a special need, this method is generally not recommended.
4. Wait for the developer to update or give up use
Sometimes reality is so cruel: some niche software developers have stopped maintaining it, and no one has taken over it. In this case, there is really no good way to continue to keep an old Mac to run these programs.
Basically these are the methods. Each has its pros and cons, and which one is chosen depends on your technical capabilities, device type and dependence on old programs. If you don't care about the hassle, virtual machines are the most flexible choice; if you only use them once a while, it may be easier to find an alternative software.

To share files between two Macs on the same network, first make sure that the two devices are connected to the same LAN, then enable file sharing on the host, set shared folders and access permissions, and then connect from another Mac through the access sidebar or manually enter the SMB address, and finally you can browse, copy or transfer files. Common problems include waiting or restarting the network when the device cannot be discovered. If the permissions are incorrect, you need to check the username, password and sharing settings. If the connection fails, you can try the SMB address. If the firewall blocks, you can temporarily close the test.

PrivateRelay is a privacy protection feature launched by Apple that hides user identities and browsing content through encryption and segmentation of network requests. The specific operation is divided into two steps: one is to encrypt the data and forward it through two relay servers. The first is to know the IP and the second is to know the content that does not know the user's identity; the second is to realize privacy isolation, and even Apple cannot obtain the complete record. Supported devices must meet: iOS15/iPadOS15/macOSMonterey and above systems, log in to AppleID and subscribe to iCloud services, and are only available for Safari browser. Its benefits include preventing ISP tracking, no additional settings are required, default activation, etc.; the limitation is that it does not support the wall surfing and only protects Safar.

To adjust the Dock on Mac according to usage habits to improve efficiency, you can follow the following steps: 1. Adjust the size and position: Go to "System Settings" > "Desktop and Dock", check "Automatic Show and Hide Dock", slide the bar to adjust the icon size; select the left, bottom or right place in "Dock Position". 2. Add or remove apps and folders: Drag the app from "Applications" to the Dock, and drag out the outside of the icon to remove the item. 3. Customize behavior and animation effects: Set click icon to display recent documents, window thumbnail previews, and use dividers or empty launchers to improve organization and quickly return to the desktop. Turning on the auto-hide function helps save screen space and make your work more focused.

iCloudDrive's Desktop & Documents folder feature enables cross-device synchronization by migrating desktop and document folders to iCloud. 1. After turning on, the system automatically moves the file to iCloudDrive to maintain local display and access experience; 2. When connected to the network, the file can be edited and synchronized to other devices at any time; 3. When Mac storage space is insufficient, the files will "slim down" with great use, only icons and names are retained, and the content will be downloaded as needed; 4. Set the path to macOS settings→AppleID→iCloud→check "iCloudDrive"→click "Options" and enable "Desktop and Document Folder"; 5. Notes include: First uploading requires stable

When deleting a file, simply throwing it into the wastebasket and clearing it will not completely clear the data. The default deletion operation of macOS only removes the file index, and the actual data remains on the hard disk until it is overwritten by new data. For sensitive information, a safer method of deletion is required. 1. Use the "Safe Delete" terminal command srmfilename, suitable for mechanical hard disks (HDD); 2. Use "Disk Tool" to erase blank space and clean up deleted but residual data; 3. Enable FileVault encryption to make ordinary deletion equivalent to safe deletion; 4. Use third-party tools such as EraserDrop to perform convenient and secure deletion. Choose the appropriate method according to the type of hard disk and privacy needs to effectively prevent data recovery.

Apple computers can format the USB disk to FAT32 or exFAT through Disk Tools. 1. Open "Applications → Utility Tools → Disk Tools", and select it after inserting the USB disk; 2. Click "Erase", customize the name, and select the format (FAT32 is highly compatible but a single file does not exceed 4GB, exFAT has no such limitation and is suitable for large files); 3. Generally, select "GUID Partition Map" for partitioning schemes. If you encounter problems, you can try "MBR"; 4. After confirming the settings, click "Erase" to complete. If the FAT32 option cannot be found, you can choose "MS-DOSFAT" instead. If it is still not feasible, it may be because the system version is old or the USB drive is abnormal. You can try restarting, changing the device, or formatting it on Windows before bringing it back to your Mac for use. suggestion
