Razer Synapse 4

This should not happen, but I have found that the beta version of the bugged mess known as Synapse 4 is actually more stable than the released version. It is still a bugged mess, and with no way of going back to Synapse 3, it is the best of a bad choice. After performing a clean install of Synapse 4 released version, it has frequently crashed, and had to be restarted.  This on every computing session, without fail.  To see what is being selected, I have Synapse open at all times.  When it disappears, I know that it has crashed. The beta version has not once crashed.  It has other annoying habits, such as not recognising when I am using a web browser, or Microsoft OneNote.  However that is also present in the released version. Quite honestly, I do not understand their rationale of restricting Synapse to only recognising certain programs.  It will cost them sales.

Hello! Is synchronisation between Nanoleaf and Synapse 4 currently available? I keep getting an error message. Has anyone else encountered this? 

For a while now Razer Synapse 4 was working great and I had no issues with it but today I opened it and it started to crash over and over a few seconds after opening - at one point it looked like it was going to try to install an update but then it said installation failed and crashed. I tried restarting my laptop and also uninstalling synapse and going to the website to download the latest version of the installer and reinstalling it but this also failed. I am running on a razer blade 18 (2024) with rtx4090 and intel core i9 14900hx on windows 11 latest udate

The latest Synapse update (I had one yesterday I think) disabled the automatic profile switch for some applications. The profiles do not switch automatically for Google Chrome or VSCode, but they do work for others like Visual Studio or some games.I tried everything that was suggested in some support threads regarding the faulty profiles switch (there are lots of them apparently, meaning Synapse is quite buggy).Razer, please debug the latest release or give me a link to an older version of Synapse 4.

Hi.I’m inviting all to conversation about never ending list of bugs in Synapse 4.Let’s open beers or more voltage alcohole like Razer DEV team and chat about issues with this app if we can call it an app.So last time I spent more time on Synapse 4 fighting with lights and synchronization with MSI app and gear than on playing or doing something more productive. What I learned is that application working like trowing a dice, each clean installation generate different problem :) fixing one but giving you new one.From what I notice there a 4 common issues:   Chroma app stopped turning on automatically with the system after login to windows account (to make lights on you need to turn on manually the Chroma app) Sometimes there is an issue where you can’t add games to Synapse 4 I notice also when you have set profile with lights for some specific game keyboard (huntsman elite in my cas

Hi, i am unable to disable auto-updates. In the old razer snypase, there was a setting for me to disable this, however, in this new razer synapse 4, I am unable to do so. When I open the settings, there is no option for me to disable auto updates. I have attached a screenshot below  

Hello,I got tired of trying to figure out stuff on my own, since everywhere I look seems to say the same things about the horrible synapse software. I tried the 4 but had profile syncing issues right out of the box (brand new peripherals and installation), went back to synapse 3 since everyone said to do so (macros where disappearing left and right, I had to export the profile and re-import every time it did...), and now I’m back on the 4 which seems to have fixed the syncing issues, but now adding other issues...I need answers to my issues.When remapping Function keys to my Naga’s side buttons. Not macros, only the basic function you could ask from this software… I have noticed that it will work for a while, but the more you use them the more delays it will create between the button press and the actual action in game. It was particularly evident when using a cursor movement macro. The macro would start and move the cursor very fast until the move

Hello, after installing Razer Synapse 4 and uninstalling Synapse 3, I encountered an issue where the Chroma profile does not switch to the one set in the Linked Games tab/module when launching a game. Have someone else encountered this problem or is that just me? And do you have solution for it?Thanks! 

I just cannot fight version 4 anymore, its absolute trash. Went back to 3 and will deal with any issues after Jan. 20th 2026 or just replace all my gear.

I’ve already sent this to support but I thought I’ll put this here too.This is an issue I have only on Synapse4.Basically, when ever I cycle keymap(I use 1 as main and 2 for some obscure shortcuts) and use it, Synapse can randomly overwrite the 2nd keymap with the mapping of 1st’s.Here’s a video of me reproducing this issue by spamming keys while cycling, but this has happened multiple times when I’m using Tautarus normally and I don’t spam keys.My temporary solution for this is to dupe the preset so I can switch to it when it happens, delete the original and dupe the dupe for next time...

fresh install time. synapse says i need to update firmware for my nommo v2’s. i make it to the page that says “push he power button, make sure the light is green,” which its on, but the “update” button is dim and unclickable. 

Ok so I’ve had the Kraken BT KItty edition headset for so long (the completely wireless one without a mic). Sadly after so long one of the ear cushions stretched out and keeps coming off and the cushion for the head has really torn. So I had gotten a new one. My old one never worked with synapse 4 when that came out so I had downgraded back to 3 (Always came up “Device is switched off”). When I not the new one, assuming it may be more compatible I upgraded back to 4 and same issue went back to 3. No issues. Recently got a new PC earlier this month and was sad to know synapse 3 is no longer available to download. If the headset is off it doesn’t show, which is normal. Once I turn the headset on my pc connects with no issue and it lists in Synapse 4 as “Device is switched off” however since I try not to wear the newer headset while my hair is wet I use the old one since it’s messed up anyway. That one now works in synapse 4 (even though it previously didn’t on the old pc) but the new

I’m here simply to advocate for Linux support. I have 3 Razer devices, headphones, keyboard and mouse and they struggle to work with Linux. Us Linux users should not have to settle for third part software like OpenRazer. While I respect their work it should not be on them to have to make these tools. We paid money for our devices, we expect support on Linux. 

Before upgrading to Razer Synapse 4, I could hold the volume up button to increase the volume continuously. Now I have to keep pressing it repeatedly. However, when I close the Razer Synapse app, holding the button works normally again.Is there a way to keep the app open and still be able to hold the volume up button to increase the volume, without having to spam the button?

Hi everyone,My device: Razer Blade 18 (2024) – Intel i9-14900HX / RTX 4080 / Windows 11 Home I’m having an issue where Razer Synapse doesn’t start automatically with Windows, or if it does, it launches very late after the system boots. Until Synapse finally loads, my keyboard shows random lighting effects instead of my saved Chroma profile. Here’s what I’ve already tried (without success): Enabled “Start Razer Synapse on system startup” in the settings. Checked Task Manager → Startup tab (Synapse is enabled). Made a custom Task Scheduler entry to start Synapse at login (with and without delay). Set Synapse to run as administrator. Verified that Razer Synapse Service and Razer Central Service are set to “Automatic” and running. Reinstalled Synapse completely (including deleting leftover Razer folders from AppData and Program Files). Despite all this, Sy

Three years ago, I discovered that Razer Synapse's macro recording was completely unable to record in-game mouse and keyboard actions. Even today, after purchasing a powerful desktop computer, the latest Razer mouse and keyboard, and installing the latest Razer Synapse, this problem still hasn't been resolved!I'm forced to manually edit my macro scripts line by line outside of the game window, which is incredibly inefficient.If I can't record any actions within the game, why would I even use Razer Synapse's macro?😡

Aside from the profile not automatically switching, even manually setting the profile as default results in it not working in the game. It keep using the default one.Anybody else experiencing this? Problems started appearing after following instructions to uninstall Synapse in regards to another issue. Double checked settings. Even did the trick of installing Chroma app to disable the apps. 

I've got a basilisk v3 and I can't even use the sensitivity clutch on it. It's the one and only reason I got this mouse. But synapse takes a full 10 seconds to recognize that I've pressed it and then it just stays on indefinitely after I've pressed it. So it's a dysfunction at best and an absolute blockade of a hiderance at worst.

Using Razer Blackwidow v3 I have two profiles on my keyboard. The first one has 'x' and 'd' keys running a macro while pressed. The second is a basic normal keyboard.Whenever i use profile 1 (Macro) and switch to profile 2 (Normal), I am unable to hold the the 'x' and 'd' keys. It will only trigger the keypress once and stop after that even though i am holding down the the 'x' or 'd' keys. It has been affecting my gameplay, hence, why I am bringing this issue up.Example, after switching back to profile 2 (Normal), presses 'x' key and hold down, presses left arrow key, 'x' key stops registering.The other keys which doesn't not have any macro registered to it does not seem to have this issue.I did not have this issue when i was using synapse 3. It was only after i updated to synapse 4 did this starting happening.

I have several razer pheripherals. By defualt I have chroma set up so that a wave colour gradient from left to right goes across my devices. Since upgrading to Synapse 4, the way the wave travels is no longer smooth. I can visibly see the colours stepping from one shade to another as the gradient moves across the devices. The effect this produces is not nearly as pleasing as it looked when the gradient was smooth. I switched back to Synapse 3 and the problem is not there. Unfortunately it looks like the Wolverine v3 Pro isn’t compatible with Synapse 3 or I would stick with that. I don’t really understand how razer have managed to ruin this effect, but I’m wondering if anyone has the same experience or if we can expect a fix.

I recently had uninstalled razer synapse 4 and reverted to razer synapse 3 after hours of trying to troubleshoot issues with razer synapse 4 crashing over and over again but I decided to try to give it one more chance and for some reason I thought, what if I try continuing as guest when logging in? FOR SOME REASON, THIS SOLVES MY CRASH ISSUE. I tried logging in again and IMMEDIATELY the program crashes over and over again. I uninstall and reinstall and  but log in this time to find that, sure enough, it still crashes on startup repeatedly. Uninstall and reinstall and continue as guest- NO CRASHES. So weird I don’t understand why this would be the case, maybe there is a bug with the profiles syncing or somehow my profiles got corrupted or something, I don’t know,… I also don’t know if this will solve the issue long term, and would like to be able to sync profiles or have access to my old profiles saved to my account, but for now at least it seems to work as a temporary fix for the cr

Hi everyone,I downloaded a macro script from Razer Synapse 3 and tried to use it in Razer Synapse 4, but it doesn’t seem to work.I noticed that normally the macro icon should show a red slash symbol when it’s active, but mine doesn’t show that icon at all. The macro also doesn’t execute when I press the assigned key.Has anyone experienced this issue before?Is Synapse 4 incompatible with macros created in Synapse 3, or do I need to reconfigure everything?Any help would be appreciated. Thanks! 

Blackwidow V4 Pro and Synapse 4 installed.If Synapse is running and I run other certain apps, like a music streaming app, multimedia keys don’t work there and volume control stops working. As soon as I exit the music streaming app, volume control shows up reacting to the roll bar with significant delay. But sometimes it stops working at all. Only if I exit Synapse, it’ll be working.I tried all the steps proposed by support documentation, like rei-installation of the keyboard driver, Windows update and clean re-installation of Synapse, but they didn’t work.
