Mastering Your Feather SSD

If at first you don’t succeed, fly, fly again!

Key facts to know:

1. If you ordered an M13 Feather SSD, you have an NVMe SSD, which means several important things:

    a. This is the fastest, newest SSD technology- #takeflight

    b. Apple allows compatibility with NVMe SSDs starting with High Sierra (and now Mojave), which means that any MacOS before High Sierra is not compatible with your drive.

    c. Your Mac must have the appropriate firmware installed to be able to read our drives. This firmware was released with High Sierra, and your current version is known as your Boot ROM number.

How do I install my drive?

For MacBook Installation, you will need the following:
-    1x Feather SSD
-    1x T5 Screwdriver (Included on request)
-    1x #2 [P5] Screwdriver (Included on request)

1.     Using the #2 screwdriver, remove all of the screws off the back of the MacBook. There will be two screws from next to the black hinge that are either longer than the rest (MacBook Air) or shorter (MacBook Pro). Keep track of these.
2.     Check that all screws are removed.
3.     Pop off the back panel of the Mac, starting right next to the hinge.
4.     Use the T5 screwdriver to remove the screw holding the SSD
5.     Swap out the old SSD for the new Fledging Feather SSD, then follow steps 1-4 in reverse to put the Mac back together.

*Need instructions for iMac, Mac Pro, or Mac Mini instead? We suggest reading over our standard installation above and looking up YouTube videos for comprehensive guidance (there are really awesome ones out there!). Please contact us if you need further assistance.

How do I transfer data to my drive?

*Note: Your M13 Feather SSD uses NVMe SSD technology, which is supported by MacOS High Sierra and beyond (Mojave), but is not supported by MacOS versions below High Sierra. Please do not attempt to erase your M13 Feather SSD and restore to an older version of MacOS. Also note that if you are trying to restore from a Mojave Time Machine Backup, please first update your M13 Feather SSD to Mojave and then proceed with the Time Machine transfer.

To transfer data from your old SSD to your new SSD, you need:
-    1x External Hard Drive
-    1x Personal old drive
-    1x Feather SSD


1.     Make sure your old drive is in your machine
2.     Plug in the external hard drive
3.     Launch Time Machine (in Applications), select the external drive as the backup disk
4.     Choose "Back Up Now" and wait for the backup to finish.
5.     Replace your old drive and physically install your Feather SSD in your machine (refer to the "How Do I Install My Drive?" prompt at the beginning of this form)
6.     Power on the Mac, pressing Option until the chimes are heard
7.     Select "Restore from Time Machine Backup" and follow the on-screen steps, or use Migration Assistant located in Applications if you have already set up your computer.

* If you are having trouble with restoring from your time machine backup using the directions above, please proceed with the following data transfer method:

You need:
-    1x External Hard Drive
-    1x Personal old drive
-    1x Feather SSD
-    1x Installer USB (if not included in your package, please make a USB Installer by following the directions at the unaffiliated website here


1.    Plug in the external drive with your old SSD mounted internally.
2.    Launch Time Machine, and select the external drive as the backup disk.
3.    Choose "Back Up now" and wait for the back-up to finish.
4.    Install your Feather SSD
5.    Plug in the Installer USB and external drive.
6    Power on the Mac, pressing Option until the chimes are heard.
7.    Select the USB from the boot menu.
8.    Select "Restore from Time Machine Backup" and follow the on-screen steps.

My computer can’t recognize my SSD- what do I do?

1. Find your Boot ROM version using one of these two methods:

    a. If you have an old working SSD on hand, boot up your computer. You can locate the Boot ROM version number by clicking the Apple icon -> “About this Mac” -> “System Report”. It is listed towards the bottom of the hardware overview. Record this number.

    b. If you do not have a working SSD, you can use recovery mode to find your Boot ROM number: * 1. Press the power button * 2. Immediately after, hold down command + R for several seconds until you see the internet recovery globe appear on your screen * 3. Choose your internet, wait for it to load, and select your language * 4. Go to utilities (tab at the top of the screen), and click on Terminal * 5. Type these words into the Terminal: system_profiler SPHardwareDataType * 6. Press enter * 7. Record your Boot ROM number 

2. Check to see if your Boot ROM is up to date using our compatibility chart.

3. If your firmware is out of date, update your Boot ROM

    a. If you have an old Apple OEM SSD or can borrow one from a friend, do the following:

        i.     You need:
            1x Apple Drive
            1x USB (8 GB or more)
            **IMPORTANT NOTE: Both will be erased in this process, please backup the drives before proceeding

        ii.     Boot up your computer with your apple drive inside. Please make a USB Installer by following the directions at the unaffiliated website here
        iii.     Make sure you have backed up your data on the USB and on your old drive!
        iv.     Turn Mac off
         v.     Power on the Mac, holding down Option until you hear chimes
        vi.     Select the USB from the boot menu.
        vii.    Select "Reinstall your Mac" and follow the on-screen instructions
        viii.    Re-install your Feather SSD and see if it is recognized now!

    b. If you do not have an old Apple OEM SSD, contact us for details about receiving an installation kit!

My computer has problems waking up from sleep.

This is a known issue that occurs when using NVMe SSDs with MacBooks from 2013 and 2014. However, you can circumvent this issue using the following steps! This will still allow for regular sleep, just not deep "hibernation" mode.

1.     Open up Terminal (open your Applications folder, then open the Utilities folder. Open the Terminal application.)
2.     Type in the following code in the Terminal:
sudo pmset hibernatemode 0 standby 0
3.     Press enter (return). 

If that didn't work, try also doing the following:

1.     Open up Terminal (open your Applications folder, then open the Utilities folder. Open the Terminal application.)
2.     Type in the following code in the Terminal:
sudo pmset autopoweroff 0
3.     Press enter (return).

My drive was working, but now is not.

Try doing a clean install of MacOS on your Fledging Feather SSD to get it up and running again.

1.     (about 30 min): If you have not already done so, please make a USB Installer by following the directions at the unaffiliated website here

2.     Follow the instructions and the video to install a clean copy of MacOS onto your Feather SSD, making sure your Feather SSD is installed in your machine when you boot it up with the USB Installer.

**If you are still having trouble, this is probably a case where your drive has become "unmounted." Please go to disk utility while booted from the USB, select the drive, and hit the erase button in the top-middle of the disk utility window. Reformat as MacOS Extended (Journaled) with GUID Partition Map. Try erasing up to ten times if you are getting an error- sometimes it just happens to work on the ninth try.

***If you still can't get the drive to erase and reformat, try ADDING a random partition to the drive that is different than the current partition, and then going back and erasing it as described above. This is a trick that we have used to get it to reformat in rare circumstances.

Enabling trim.

You can enable trim on your SSD for future performance. It is super simple:

1.     Open Spotlight search by pressing command and the space bar together.
2.     Type "terminal", then press "return".
3.     Copy and paste the following command to terminal:
            sudo trimforce enable
4.     The system will warn you about data loss, but we have never experienced that, so do not worry! Press Y, then return.
5.     The System will reboot, and trim will be enabled.

Why was Fledging founded?

Fledging was founded because we believe that premium electronics, starting with replacement SSDs for Mac, should be accessible to everyone. Thank you for supporting our cause!

How can I make my computer boot up faster?

When you put a new SSD in your computer, your MacBook no longer natively recognizes your SSD. This means that it takes longer for your MacBook to boot up. However, there is a nice workaround called "blessing" your drive that we discovered in order to make your MacBook boot up just as fast as its original OEM drive. You can find the step-by-step details here
