# Symphony Studio firmware Update flash

## If you have been instructed by Apogee support to re-flash the firmware of your Symphony Studio, this is how to do it.

#### Although it is unusual, sometimes the firmware in your Symphony Studio has to be re-flashed. Under normal circumstances firmware updates are a part of the Control 2 / Symphony Studio update package, and there is no need for a stand alone firmware updater application - It just runs as part of a normal update.

NOTE: This does not change the version of the firmware. It is only a means of refreshing the existing firmware should there be problems.

- First, change the contents of the ***SymphonyStudioVersion.txt*** file on your Mac to a version number that is higher than the currently installed version of firmware.

NOTE: You cannot change the text file while it is ***in place***. The next few steps walks you through the process.

- From Finder use the “Go to folder” feature: ⇧ shift + ⌘ command + G and paste in
  
  ```
  /Library/Application Support/Apogee/Firmware
  ```
- Drag **SymphonyStudioVersion.txt** to the desktop. It will NOT “move” it, it will create a copy.
- Open the copy on your desktop. You will see the version number of the current firmware. Your version may be different, this is just an example.

![](https://knowledge.apogeedigital.com/hs-fs/hubfs/SymStuVersion-png.png?width=453&height=189&name=SymStuVersion-png.png)

- Change the last number to a number that is at least 1 number *higher* and SAVE the text file. For example you would change 0.0.35 to 0.0.36 and SAVE. Your numbers may be different.

![](https://knowledge.apogeedigital.com/hs-fs/hubfs/SymStuVersion2-png.png?width=454&height=208&name=SymStuVersion2-png.png)

- Back in */Library/Application Support/Apogee/Firmware,* **DELETE** the original **SymphonyStudioVersion.txt** file. You will be prompted for your password.
- Drag the copy you just altered from your desktop back into */Library/Application Support/Apogee/Firmware.*
- If you have your desktop set to be backed up to iCloud, you will see a warning asking *“Are you sure you want to remove “SymphonyStudioVersion.txt” from iCloud Drive?"* Click MOVE. (*If you don’t have your Desktop set to be backed up to iCloud you won’t see this*)

![](https://knowledge.apogeedigital.com/hs-fs/hubfs/AreYouSure-png.png?width=301&height=306&name=AreYouSure-png.png)

- You will be prompted for your password.
- Go to your Utilities Folder ⌘command + ⇧shift + U and open **Activity Monitor**. (/System/Applications/Utilities/Activity Monitor.app)
- **1**-Search for **Apogee** in the search bar, **2**-select **ApogeeGlue** and **3**-click the **Stop button**.

![](https://knowledge.apogeedigital.com/hs-fs/hubfs/ActivityMonitor3-png.png?width=688&height=260&name=ActivityMonitor3-png.png)

Click on **Force Quit** from the prompt.

![](https://knowledge.apogeedigital.com/hs-fs/hubfs/ActivityForceQuit-png.png?width=688&height=265&name=ActivityForceQuit-png.png)

- In just a moment after force quitting Apogee Glue, you will see the “New firmware is available” prompt. Your numbers may be different.

![](https://knowledge.apogeedigital.com/hs-fs/hubfs/NewFirmware-png.png?width=481&height=242&name=NewFirmware-png.png)

- Click Update.
- On your Mac you will see the ***initial*** progress bar for the Firmware update indicating the ***transferring*** of the file to your Symphony Studio.

![](https://knowledge.apogeedigital.com/hs-fs/hubfs/firmware%20in%20progress%2001-png.png?width=490&height=247&name=firmware%20in%20progress%2001-png.png)

- Next you will see “Please Wait”

![](https://knowledge.apogeedigital.com/hs-fs/hubfs/PleaseWait02-png.png?width=491&height=247&name=PleaseWait02-png.png)

- At this point the **front panel** of your Symphony Studio will display a progress bar. (This is the ***secondary*** progress bar, indicating the ***writing*** of the file, this time displayed on the front panel of your Symphony Studio.)

![](https://knowledge.apogeedigital.com/hs-fs/hubfs/UpdatingFirmware-png.png?width=431&height=316&name=UpdatingFirmware-png.png)

- When this process is finished your Symphony Studio will shut itself off.
- The firmware has been successfully re-flashed.
- Turn the Symphony Studio back on.
- After a moment you will AGAIN see the “New firmware is available” prompt. This is normal.

### **THIS CAN NOW BE IGNORED - Click Close**

### **![](https://knowledge.apogeedigital.com/hs-fs/hubfs/NewFirmware-png-1.png?width=439&height=221&name=NewFirmware-png-1.png)**

NOTE that from this point forward you will see the “New firmware is available” prompt every time you power cycle or hot plug your Symphony Desktop - this is normal. To remedy this or “put things back to normal”, repeat these steps:

- Go to */Library/Application Support/Apogee/Firmware*
- Drag **SymphonyStudioVersion.txt** to the desktop. It will NOT “move” it, it will create a copy.
- Open the copy on your desktop. You will see the version number that you created earlier. 0.0.xx. Change the last number ***BACK*** to what it was before you changed it.
- So, if you changed 0.0.35 to 0.0.36 to force the flash update, you will now **change it back to 0.0.35**.
- Back in */Library/Application Support/Apogee/Firmware* delete the **SymphonyStudioVersion.txt** file.
- You will be prompted for your password.
- Drag the copy you just altered from your desktop back into */Library/Application Support/Apogee/Firmware.*
- If you have your desktop set to be backed up to iCloud, you will see a warning asking “Are you sure you want to remove “SymphonyStudioVersion.txt” from iCloud Drive?
- Click **MOVE.** (*If you don’t have your Desktop set to be backed up to iCloud you won’t see this*)

**![](https://knowledge.apogeedigital.com/hs-fs/hubfs/AreYouSure-png-1.png?width=313&height=318&name=AreYouSure-png-1.png)**

- You will be prompted for your password.
- That completes the process. Your firmware has be refreshed.
