These days, just about everyone has at least two or three computer devices. Whether it’s a laptop, tablet, desktop, or phone, you’ve probably got data stored in a few different places. However, a lot of people assume that the only way they can keep updated between devices is by manually transferring data, ensuring that everything has the same information. This is time-consuming and completely unnecessary. In reality, there are plenty of ways that you can keep devices synchronized without having to do the work yourself. By doing this, you can SMS synchronize and keep contact details and message history the same between your phone and computer. You can also ensure that all photos are shared across devices, and even keep your music and film library synchronized.

I. What is Synchronizer Software?

Synchronizer software refers to programs that are designed to update files between various different devices. There are a number of different variables that define how these programs are used. The most obvious one is whether or not a device is designed to update files automatically. For instance, some users might want all devices to share the same files, but other users might specify one device as a work device (for instance a laptop) and not need the files kept there on their other devices.

Another defining feature of a synchronizer is whether it uses one-way synchronization (also called mirroring) or two-way. With one-way, all devices copy the content of one master device. In two-way, when files are changed on any device, all devices are automatically updated with the new files. With all synchronizer software, it’s important to take into account the storage space of the devices you’re using. Mobile devices obviously have far less storage space than computers, so if you’re using an automatic synchronizer, it will be very easy for you to take up all space on your portable device without realizing it.

II. Top 10 Mac Synchronize Software Tools

We’ve put together a list of ten of the best Mac synchronizer tools on the market. As we’ve mentioned above, there are a few main differences between different tools and how they work, which need to be taken into account when making your choice. On top of that, other factors such as ease of use, compatibility, price, and a number of different features are all things you’re going to need to consider. This list will give you a quick overview of a load of different tools, taking into account their good and bad features, and make it easy for you to pick the best synchronizer for your needs.

1. SyncMate

SyncMate Expert

Requirements: OS X 10.10. 50.9MB free space. Version 8.1.475. (30 Mar, 2020). 4.9 Rank based on 374+ users, Reviews(978)
Category: System Utilities

If you’re looking for a reliable synchronization software, SyncMate is a great choice. This program has really good compatibility in OS terms, meaning that you should be able to synchronize folders no matter what devices you are using, or how many.

File Synchronizer

It’s also great with cloud storage and can sync with Microsoft storage programs. It can handle just about any kind of file that you would want to be synced between devices.

Supported devices: macOS, Android, iOS

Pros and cons: SyncMate is versatile, and can handle a wide range of files, including music, video, and contacts. You can also directly manage content on your devices from your computer, rather than having to manually delete from the device. Everything is backed up directly to the hard drive, and you can also sync multiple different Macs. You do need to upgrade to Expert edition if you want the most out of it, but it’s an affordable choice.

Conclusion: We reckon this is probably the most impressive out of all the options we looked at. It can handle pretty much any device or operating system you’re likely to have. With high usability and plenty of different options, it’s a great choice no matter what your sync needs.

2. FreeFileSync

This file synchronizer’s main selling point is the fact that it is open-source, and completely free of charge. This means that it is available to pretty much anyone looking for a way to synchronize folders. In this case, the definition of syncing devices is somewhat limited, but this program is still good for someone looking for a straightforward tool that will keep their files safe in case of damage, loss, or accidental deletion.

Supported devices: Mac, Windows


Pros and cons: Obviously, one of the best things about this software is the fact that it is free and open-source. However, to be honest, there are many programs out there that have more to offer than this. For starters, the program isn’t compatible with portable devices - it’s solely designed for backing up files on computers. That means that there are limited uses. It is also not capable of two-way sync, as this is obviously not what it has been designed for.

Conclusion: If you want the basics, this program delivers, and you don’t need to spend anything. Other than that, you may want to check elsewhere for programs that can deliver more features. It is more than capable of doing basic tasks, but anything more complicated will not be an option.

3. GoodSync

GoodSync is a popular synchronization program with a lot to offer. The program is versatile, running on all major operating systems, and compatible with portable devices as well. There are two different options, personal and business, each one specifically designed for slightly different uses. If you are looking for a capable sync program that can be used across a range of different systems and products, this is probably a pretty good choice for you.

Supported devices: Mac, Windows, Linux, Android, iOS


Pros and cons: GoodSync can be used with all the most widely used operating systems and devices. The automation option makes it easy to ensure that your files are always safely saved somewhere and that your devices are in sync. However, online reviews mention that some people have had difficulty with tech support. Also the program is constantly updating, which can have some impact on its usability, and take up unnecessary time. Another issue pointed out is that the program can struggle when you update your hardware.

Conclusion: GoodSync is a reliable and versatile program, with plenty of useful gear to offer. You can get it in free or paid options, meaning that you’ll need to spend some money if you want to get the most out of it. You can synchronize calendar info and other files. And there are a few minor issues, such as problems with support. But all in all, it’s a pretty reliable option.

4. Unison

Unison is, at first glance, a straightforward file synchronizer, but it actually has a lot more to offer than you might think. The website may look outdated, but once you check what it is capable of, it becomes clear that Unison is actually a pretty good option. Another plus point for the software is the fact that it is available completely free. It is also a versatile choice of file synchronizer.

Supported devices: Mac, Windows, Unix


Pros and cons: The first obvious advantage of Unison is that it is free - it is open-source code. It almost seems like it has been developed more as a project, than as a money maker. Another big benefit of Unix, and something that sets it out from other programs, is that it is a two-way sync program - changes are copied to both versions of a file. However, some users have pointed out that it cannot handle international characters in file names, and also that the GUI regularly crashes on Mac.

Conclusion: Unison has a lot to offer, especially considering that it is free. The main drawbacks are the slightly dated, and not especially user friendly, way the program runs. And as has been mentioned, the GUI is prone to crashing on Mac. But it’s still a good choice, and definitely, one to consider.

5. Sync Gateway

This program has a lot to offer to anyone looking for a reliable synchronization tool. It has a lot of versatility, working with a wide range of different platforms and device types. It is also free, which is not a common feature for software with this much to offer. A number of other features make this program stand out from the competition, though it does also have a few drawbacks.

Supported devices: macOS, Windows

Sync Gateway

Pros and cons: The first thing to say about this program is that they’ve made an effort to include a lot of useful features in there. It is capable of two-way sync, meaning that you can keep updated between devices with minimum difficulty. In fact, you can program it to run multiple different sync schedules between devices and folders, or just keep everything updated together. Unfortunately, if you want to get the most out of it, you will need to upgrade to the paid version. Also, it’s not always as fast as you’d expect it to be.

Conclusion: All in all, a pretty good choice. Unfortunately, while there’s a lot on offer, you do need to pay to unlock it, so that’s something worth considering if you just want a straightforward solution. However, Sync Gateway definitely has a lot to offer.

6. Syncovery

This program has a lot of features, making it a useful choice for pros or anyone looking for a tool with more variables. They’ve included an interesting Exact Mirror feature that lets you update new files with earlier versions of themselves, something that would probably be of greater use for businesses. They’ve also included the usual selection of features that you’d expect on the software of this kind, making them a pretty versatile option.

Supported devices: macOS, Windows


Pros and cons: The great thing about Syncovery is that they’ve included a really wide range of features. The program is compatible with support for a huge range of online cloud systems, making it a good choice for anyone using a number of different online backup and storage tools. The one thing we will say is that, while having this many features is a good thing, it may be too much for the average user. If you’re just looking for a straightforward sync tool, you may want something simpler.

Conclusion: All in all, if you’re a professional looking for something that gives you a lot of options, this is a great choice. There are a lot of different options, and a wide range of supported tools is a great help. But if you’re looking for something straightforward, you may want to consider a different option.

7. Resilio Sync

Resilio is a pretty comprehensive folder synchronizer software, available in a range of different versions depending on your situation and how much you want to pay. You can invest in a business version, or even a family one if you have many different people and devices in your home. It’s a versatile tool with many different options and a few added bonuses that set it out from other similar solutions.

Supported devices: macOS, Windows, Linux, Android, iOS

Resilio Sync

Pros and cons: It’s great that you can pick a different package depending on your needs. For instance, the Family version can support up to 5 different users. There’s also a useful option to encrypt and decrypt files. Unfortunately, Resilio isn’t the cheapest option out there. While you can purchase some versions with a one-off payment, it’s still quite an expensive choice.

Conclusion: Resilio definitely has a lot to offer. Customized packages mean that you can ensure you get the features most useful to you, such as synchronize contacts or other details. It’s also an easy-to-use program, and once it’s up and running, you can pretty much leave it to ensure that everything is synced perfectly. If you’re willing to pay extra, this is a good choice.

8. ChronoSync

This program has quite a lot going for it. One of the most notable features is the option for a bootable backup - you can save it to a drive, and if your entire system crashes, you have the means to get it back up and running. Beyond that, there are plenty of syncing options, including cloud storage, and the detection of deletions between different devices. It can run in the background without interrupting any ongoing processes.

Supported devices: macOS and iOS


Pros and cons: Obviously, if you’re looking for a way to do Mac synchronization, this is a pretty good bet. It’s got everything you need, and you can easily set schedules for automatic backups. The bootable backup is also a great feature. However, this program is aimed squarely at Apple customers - if you have any non-Apple devices, it won’t be compatible.

Conclusion: For someone who only buys Apple products, this is probably a good bet. However, if you have Android or Windows in use, you’ll need to find a different option. While this has some great features, the lack of compatibility on multiple platforms is a big stumbling block.

9. Syncplicity

This is a cloud-based sync solution that has quite a lot of good features and is a folder synchronization mac users can do. One of the best things about it is the fact that it’s comparably cheaper to many other options out there. It makes use of two different desktop tools, a virtual network drive, and a multi-folder sync mechanism, to carry out straightforward syncing tasks. You can easily dictate which folders are to be shared, and where they are to share.

Supported devices: macOS, Windows, Android, iOS


Pros and cons: The good thing about Syncplicity is that it can easily carry out the most basic sync tasks, and the two desktop apps are efficient and easy to run. It’s also a fairly cheap program. However, there are a few issues with it. The portable apps aren’t great, and for some reason, sharing data from a device to a computer is more complicated than it should be.

Conclusion: This program is a pretty good choice, especially if you don’t want to spend too much money. However, it does have some drawbacks. There’s not a huge amount of space on offer, but given the low price, it’s not a bad option for personal use, if you aren’t expecting to sync huge amounts of data.

10. SugarSync

SugarSync offers users with everything they need to back up their files and share between devices on clouds. The number of devices is unlimited, so if you’ve got a lot to connect, you’ll have no problems with this tool. They’ve got custom-developed apps for Android and iOS phones and tablets, making it easy to keep things synced up on all your portable devices. SugarSync also ensures that your file security is never compromised, thanks to encryption.

Supported devices: macOS, Windows, Android, iOS


Pros and cons: The good thing about SugarSync is that it’s all pretty easy to use. The apps are straightforward, and file synchronization is simple. One of the main issues is that it doesn’t support programs such as Office Online and Google Docs. Given that these are very widely used programs, it’s quite a big drawback.

Conclusion: This is a great synchronizer for anyone with a lot of different devices and operating systems. It’s pretty easy to use, and has all the basic features. The lack of compatibility with certain online programs is a problem, but if you don’t use Office or Google Docs, you won’t be affected.


A synchronizer works by checking the files on various parts of a network, and ensuring that they are always up to date. That means deleting files, updating them, and moving new files from place to place. It can be done either manually, or automatically.
Transfer software is simply concerned with moving files from one place to another. While this is obviously a major aspect of synchronizing, the greater part is about ensuring uniformity across different storage - so also deleting and updating.
People use file synchronization software for many different reasons. One aspect is backing up - ensuring that a copy of files is kept somewhere safe in case the original files are damaged or deleted. Another function is sharing data with others via a cloud. They are also used to make sure the same contacts and files are available on both portable devices and computers.
Many people use a mac file synchronizer to make sure they have the same music files on their computers and the portable device. The same can be done for videos. For professionals, syncing is a useful way of making sure contact details and calendars are kept up to date between devices, or to email synchronize so your messages are up to date. You can even make use of a firefox bookmarks synchronizer. You can also create bootable data, in case you need to reboot your computer from scratch.
This depends on many things - the power of your CPU, your internet connection, and the kind of synchronizer you use. Some are faster than others, and there are different methods of syncing. In general, once you have synced devices, future synchronizations will be much quicker, as you will only be updating new files as they are created or changed.

As you can see, there are a ton of different options out there. Depending on what you need syncing software for, you may find some of these choices more attractive than others. Regardless of your needs, we recommend SyncMate as our pick of the lot. It’s versatile, affordable, and can carry out just about any task you might need.
