Stellar Data Recovery for Mac is an app designed for when you’ve deleted or lost files out of your flash drive or Mac machine, and you didn’t have a backup. During my test, the app successfully located all the pictures I had erased from a 32GB Lexar drive (Scenario 1), and it also found many recoverable files from my internal Mac hard drive (Scenario 2).

Therefore, I think it’s a powerful Mac data rescue software that works to do what it has to offer. But it’s not perfect, as I found that the disk scanning process tends to be very time-consuming, especially if your Mac has one large volume (most users do). Also, due to the nature of data recovery, it’s likely that you may not be able to retrieve all your lost data unless you act quickly before those files get overwritten.

Note that once you find files missing from your Mac or an external drive, stop what you’re doing (to avoid generating new data that might overwrite your old files), then give Stellar Mac Data Recovery a try. Of course, do this only when you don’t have a backup to use.

What I Like: It offers many recovery modes to deal with different data loss scenarios. ​The app supports a large number of file formats and various storage media. Preview ​allows you to gauge whether files are recoverable or not. The “Create Image” feature is useful and convenient.

What I Don’t Like: The scanning process is ​time-consuming ​in some recovery modes. The “Resume Recovery” feature is buggy (more details below). It’s a bit pricey.


Have you ever experienced this: you were looking for some files on your Mac computer, only to find that they have been trashed, and you wondered whether there was a way to recover them. Losing valuable data can be upsetting, even devastating especially when you don’t have a Time Machine backup at hand. Fortunately, there are data recovery software that could help.

Stellar Data Recovery for Mac is one of the popular solutions in the market. In this review, I’ll show you its pros and cons, so you get an idea of whether the app is worth trying or not. If you decide to try, this article also serves as a tutorial to guide you through the recovery process.

Stellar Data Recovery for Mac: Detailed Review & Tests

Disclaimer: the review below is a fair reflection of what Stellar Mac Data Recovery claims to offer and the results I got after using the program. It is not intended to serve as an official or professional examination of the software. Because Stellar Data Recovery for Mac is a powerful app that actually includes a handful of smaller features, it’s unrealistic yet impossible for me to test all the features since I’m unable to prepare those data loss scenarios.

My testing principle is: I try my best to mimic common data loss scenarios, i.e. deleting a list of photos from a 32GB Lexar flash drive – similar to a situation when you accidentally deleted some photos from a digital camera and wanted them back. Likewise, I emptied the Trash on my Mac hoping to test Stellar’s recovery capabilities on internal Mac hard drives.

Download and Installation

Step 1: After downloading the application to your Mac, drag it to the Applications folder. Double-click on the software icon. You’ll see a message window pop up asking for permission. Choose “Open” and you’ll be prompted to input user login password.

Step 2: Browse and read the license agreement. Click “I Agree” to continue. Stellar Mac Data Recovery initializes…

Step 3: Finally, the program launches. Here’s how its main interface looks.

The main interface of Stellar Mac Data Recovery

Two main user scenarios for data recovery software are recovering data from Mac’s internal drive (HDD or SSD), and recovering data from an external drive. I’m here to use my Macintosh HD and a Lexar flash drive as the testing media.

After connecting my Lexar drive, Stellar shows the disk on the left panel immediately, together with information like disk volume and the file system associated with the disk drive.

Scenario 1: Recovering Data from an External Storage Media

Preparation: I first transferred 75 pictures from my Mac to my Lexar USB drive, then deleted them from the disk. I wanted to see if Stellar Data Recovery would find them.

Step 1: I highlighted the Lexar drive. The program asked me to select a scanning method. As you can see, there are four options listed:

Stellar Data Recovery detected my Lexar drive, and asked me to select a scanning method.
  • Recover Data: Good for scanning storage media to recover lost data — but you don’t know how the data is lost.
  • Deleted Recovery: Good for recovering accidentally deleted files like photos, music, videos, archives, documents, etc. from a storage media that is still working properly.
  • Raw Recovery: Good for recovering data from severely corrupted storage media — for example, when your camera SD card is corrupted or external hard drive crashes.
  • Create Image: Used to create an exact image of a storage drive. This can be used when the device isn’t available during the scanning process.

Step 2: I selected the Deleted Recovery mode, then Quick Scan, and hit the “Start Scan” button to continue. Pro tip: You can also choose Deep Scan if Quick Scan didn’t find your deleted photos. But remember that Deep Scan takes more time to complete.

I selected the “Deleted Recovery” mode…

Step 3: Scan…the process was very quick. It only took the software about 20 seconds to finish scanning my 32GB Lexar drive — seems very efficient!

Stellar Data Recovery was scanning my 32GB Lexar drive…

Step 4: Boom…scan completed! It says “Total 4.85 MB in 75 files in 8 folders.” Looks good. But wait, are they really the photos I deleted?

Step 5: As I said in the summary above, one thing I like about the app is its file preview ability. To check whether the found items are what I deleted, I double-clicked each file to preview the content. And yep, they are all there.

Stellar Mac Data Recovery found all of my deleted pictures!

Step 6: Well, you can preview the photos, but to save them you’ll need a registration key. How to get it? You have to buy from Stellar official store, and a key will be delivered to your email instantly.

Here’s the limitation of the demo version, it allows you to scan a disk but not to save the found files.

My personal take: The “Deleted Recovery” mode is very powerful, and it successfully located the 75 pictures I deleted from a 32GB Lexar flash drive — 100% recovery rate. Thus I believe this is the first recovery mode you should try, if you have accidentally erased some files off a digital camera card, external drive, or other storage devices. The scanning process is lighting fast, and chances of recovery are high as long as you act quickly.

Scenario 2: Recovering Data from Internal Mac Hard Drive

Stellar claims on its official website that the app is able to identify 122 different file types. In the following test, I’m trying to figure out what types of files it can retrieve from my Mac (solid-state drive with a single volume 450 GB in size). Before I did so, I emptied the Trash on purpose.

Step 1: To start with, I opened the software, then highlighted the Macintosh HD it detected.

Step 2: It asked me to select a scanning method. There are four options there (which I have introduced in Scenario 1). I chose “Deleted Recovery” to proceed. Pro tip: If you formatted a Mac partition, select “Recover Data”; if one of your Mac partitions is corrupted or lost, select “Raw Recovery.”

Step 3: Now’s the time-consuming part. Since my Mac has only one partition with 450GB in capacity, it took Stellar Data Recovery about an hour to finish only 30% (see the progress bar). I estimated it would take more than three hours to complete the entire scanning.

Step 4: Since it has already found 3.39GB data, I decided to stop the scan to get an idea what these files look like.

– Graphics & Photos: all found items were categorized into six different folders based on file types, i.e. PNG, Adobe Photoshop, TIFF, JPEG, GIF, BMP…all pre-viewable.

– Documents: the three folders included Adobe PDF, MS Word, MS Excel. To my surprise, I could also preview partial content in these documents. Bonus!

– Applications: The emails were what interested me, as I’d deleted some from the Apple Mail app. Aside from those, the program also found a list of application files including Adobe Illustrator, iCalendar, etc.

– Audio: These were mostly songs I’d deleted in AIFF, OGG, MP3 formats.

– Archives: BZ2 Compressed Tar and Zip archives were found.

– Video: It found some .MP4 and .M4V files. Another surprise, I could preview videos as well. Double-click one, and it automatically played via QuickTime app.

– Text: Many RTF files. They can be previewed as well.

My personal take: Stellar Data Recovery for Mac did a pretty good job in identifying many types of files deleted from my Mac. They included the types of photos, videos, audio, documents, apps, etc. that I deal with almost daily. In this regard, I think it’s very powerful. Another perk is the software allows me to preview the content in these files. This feature saves me time gauging whether the files are what I actually deleted. One thing that I’m not quite satisfied with is the scanning process, which is very time-intensive. But another feature that I appreciate is “Resume Recovery,” which is designed to save scan results if you’re partway through, then resume the process when it’s convenient for you. See Scenario 3 below for more details.

Scenario 3: Resume Recovery

Step 1: I clicked the back button. A new window popped up asking me if I wanted to save the scan information. After selecting Yes, it directed me to choose a destination to save the scanning process. Note: here it shows a “Total 3.39 GB in 17468 Files in 34 Folders.”

Step 2: I then went back to the main screen and selected “Resume Recovery.” It loaded the saved scan result to continue.

Step 3: Soon, the “Scan Completed!” message appeared. However, it only loaded 1.61 GB data. Remember initially it showed 3.39 GB? Surely some parts of the results were missing.

My personal take: It’s nice to see Stellar offering this Resume Recovery mechanism so we can scan the Mac drive whenever we want. Like I said, if your Mac has a big size partition, the scanning process tends to time consuming. It’s boring simply waiting for the program to finish the entire scan, especially on a large drive. Therefore, the Resume Recovery feature is very useful. However, during my test, Resume Recovery didn’t cover all the results from the previous scan result. It only returned “Total 1.61 GB in 17468 Files in 34 Folders”, while previously it was “Total 3.39 GB in 17468 Files in 34 Folders”. Where was the missing 1.78 GB data? I have to wonder.

Limitations of The App

First of all, Mac file recovery software isn’t universal. It can’t recover files that have been written over. For example, if you deleted files from a digital camera and continued using the same memory card to save new photographs, the storage space your initial files occupied could have been overwritten. If that happens, it’s impossible for third-party data recovery software to retrieve any data. So, you have to act as soon as possible to maximize the chances of recovery.

Another scenario that Stellar Data Recovery software probably won’t help is: If your Mac is using a TRIM-enabled SSD (Solid State Drive), chances to recover deleted files are slim-to-none. This is due to the difference between how TRIM-enabled SSDs and traditional HDDs manage files. Simply put, deleting a file using normal methods like emptying Trash will result in a TRIM command being sent, and a solid-state drive will eventually remove the data for good. Hence, it’s extremely difficult for any recovery software to scan and collect the lost data. That’s also why SSDs matter when you attempt to permanently delete files on Mac.

Also, Stellar Macintosh Data Recovery doesn’t support data recovery from storage media enabled by iOS or Android operating system. It only supports HFS+, FAT, NTFS based storage devices. That means you can’t use it to recover data from iPhones, iPads, or Android devices. Instead, you may have to use third-party apps like PhoneRescue which I reviewed earlier.

Is Stellar Data Recovery for Mac Worth It?

The software managed to recover all of my deleted photos on a Lexar USB drive and found a large variety of recoverable items on my internal Macintosh HD. But it isn’t perfect, as I pointed out above. Priced at $149, it certainly isn’t cheap, but if you have accidentally removed an important file on your Mac or a precious photo from your camera, you know that something is priceless.

Also, don’t forget the price that data loss causes — I mean, the anxiety, panic, etc. In this regard, it’s good to have a data rescue app like Stellar that can at least give you some hope, even if it’s not 100% guaranteed.

Compared to professional data recovery services which could cost you a few hundred or thousand dollars, Stellar Mac data recovery app isn’t expensive at all. Don’t forget that the app offers a free trial you can take advantage of. It’ll scan your drive, preview found items, and check to see if your lost files are still recoverable.

Therefore, I think the program is worth it. Once again, make sure you download the demo version for a try first. Only consider purchasing the license when you are sure your data is recoverable.


We live in the digital age; it’s sometimes easy to accidentally delete files from our devices with a few clicks or taps. And once that precious data is gone, it can be a nightmare if you don’t have it backed up.

Fortunately, a Mac app like Stellar Data Recovery for Mac may assist you to get back that lost information — as long as you take proper precautions and act quickly. The software isn’t perfect. I found a few bugs during my test; the scanning process tends to be long if your Mac has a large volume. But, the software does live up to what it aims to do — bringing back the data you deleted or lost from the dead. The program is safe, easy to use, and offers a free feature-limited demo. I’d be happy to put the app into my rescue list, just in case.

The last thing I want to remind you about is the importance of data backup. It may sound old-school, and you probably hear it all the time. But it’s still the most effective and efficient way to prevent data loss disasters. Think about that feeling: “Oh no, I deleted something by mistake! Oh yes, I have a copy saved on my external hard drive…” So, you get my point. Backup is always king.
