Razer Synapse

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 crash

Ok, so this is probably a dumb question but how do I associate a Chromo Studio profile with a keyboard profile on my Blackwidow v4 Pro Keyboard in Synapse v4? I used to be able to do it really easily in Synapse v2 (I skipped v3). To be clear when I change to keyboard profile 1 I want to display  only the QWERTY keys in green and everything else in blue. When I change to profile 2 I want it to display only the QWERTY keys in blue and everything else in green. Simple (and not real) example but I can’t make it work. I don’t want the change to be linked to a specific game, the only thing changing is the keyboard profile. I can make it work if I select quick effects in the lighting tab but when I select Advanced Effects it doesn’t save different choices under the Chroma Studio dropdown. I’m sure I am missing something obvious but for the life of me I can’t see what. Thanks in advance for any help you can give

Hello.I'd like to suggest a feature for Synapse 4 regarding the Razer Huntsman V3 Pro 8KHz.I also own a Razer BlackShark V3 Pro headset. On the headset, the physical volume wheel controls both audio devices at the same time: Razer BlackShark V3 Pro - Game Razer BlackShark V3 Pro - Chat This works perfectly.However, on the Huntsman V3 Pro keyboard, the volume wheel only controls the Game (by default in the system) channel. The Chat channel is completely unaffected. This is inconsistent — both are Razer peripherals with volume wheels, but they behave differently.My request:Please add a "Game+Chat (sync)" mode for the Huntsman V3 Pro volume wheel in Synapse 4, so it can control both channels simultaneously, just like the BlackShark V3 Pro headset does.This would make volume control much more convenient and consistent across Razer devices.Thanks!

So i just bought a new Razer Basilisk V3 today. When i tired to connect it to Razer Synapse, it wouldn’t show up. I have an M1 MacBook Air (2020) in good condition and the mouse works well. It’s way better than my old mouse. But it comes with RGB and an extra button, which I would like to customize. Is there any possible way for me to do that with my Mac? ( I’ve seen different versions of this mouse like the pro one, but the box doesnt seem to say pro or any numbers next to it, just Basilisk V3 )

Hello,I have just installed Razer Synapse 4, I had the 3 before, and now it refuses to install the drivers for my devices, it downloads in a loop, any idea how to adjust it ? and if I stop the infinite download and it refuses to start again 

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, Synapse still doesn’t appear in the system tray after boot, and the lighting only applies if I manually open the app. Is there any reliabl

So, I’m obviously not the first person to say this, which makes it even more infuriating, but Synapse 4 is the worst experience I’ve ever had with a software in my life. I don’t understand how a supposed “upgrade” to Synapse 3 is STILL a broken and buggy mess this long after it’s been launched, when Synapse 3 worked perfectly fine. If I could, I’d just stay with Synapse 3 indefinitely, but of course, Razer is forcing everyone to switch over within the next few months. I’ll just start with the main minor inconvenience I’ve dealt with: Synapse 4 takes absolutely forever to start up. So instead of seeing the custom profile that’s stored in my keyboards’ onboard memory, I see the generic ugly solid orange, green etc., until I fully log in and wait 10-15 seconds. This isn’t the end of the world, but definitely an annoyance, because with Synapse 3, it was pretty much instant and even started up when I was still on my computer’s log-in screen. What is even the point of having the onboard memo

Hi everyone,I’m posting this because I would like to know if anyone else is experiencing the same issue with Razer Synapse 4 and the Razer Kraken V3 Pro. For almost a year, I have been dealing with an audio-related issue on my Kraken V3 Pro. After trying many possible fixes, I have found that the problem only happens when Razer Synapse is installed and running.When Synapse is removed or you disable audio signal enhancements ( video example, at the end ), the issue disappears. The main problem is that volume changes are delayed across the whole system.When I lower or increase the volume, the actual audio level does not change immediately. Instead, the volume change is applied after around 1–4 seconds.This happens when changing volume through:Windows volume slider Spotify volume slider Other app volume controlsThe audio itself is not delayed. Only the volume adjustment is delayed.This becomes very annoying and sometimes painful because when a notification plays or a new audio source star

This used to work fine, but for the past few weeks (probably following an update), Synapse now opens to the desktop after Windows starts.I’ve checked the setting in Synapse, and turned it off and back on.I’ve also checked the Run registry setting which appears to be correct."C:\Program Files\Razer\RazerAppEngine\RazerAppEngine.exe" --url-params=apps=synapse,chroma-app --launch-force-hidden=synapse,chroma-app --autoStart=1Generally, Synapse 4 has been more stable this year and having release notes at long last is a welcome improvement. Just a shame I now have this new bug.

razer synapse 4 i download it and press launch but the crosshair loads for 1 sec and nothing happen  i just got new razer mouse and i can use it because software problems (:

Hello everyone, I would like to share a situation to see if you have ever experienced this. I have constantly noticed that sometimes my devices do not turn off the lights when the monitor turns off, I use this setting because when I am away the screen turns off. I could see that Synapse conflicts with the Chroma module, as there is an option for each device in Synapse to individually configure the lights as you wish, including turning off the lights when idle for some time and when turning off the screen. However, this option also exists in the Chroma RGB module, and I noticed that even when checked in Synapse, when we restart the PC, the option in Chroma RGB remains unchecked, causing the lights on my mouse (Naga Trinity) to not turn off most of the time, and others on my keyboard (Huntsman V2 Analog) as well, forcing me to go to the module and check the option "Apply to other Chroma-enabled devices", and check the box "Turn off when monitor is off" again.   

  I have made some screen-shots to make it easier to explain to me, because I have no idea what to do.

The latest update to Chroma RGB has caused my Chroma Connect to disconnect and lose my MSI motherboard everytime my computer goes to sleep and wakes up.  I end up having to restart the computer to get Chroma Connect to see my MSI motherboard and MSI Mystic Light Again.  I have verified that the MSI software is set to Razer and it is every time.  

I am experiencing a critical issue with Razer Synapse 4 where the software completely refuses to write or apply any custom configurations, macros, or keyboard rebinds down to my wired Razer DeathAdder V3.When I assign a macro (e.g., an automated "E" key loop) or a basic keyboard function directly to Mouse Button 4, Synapse 4 visually displays the change as saved and linked on my monitor. However, the physical hardware continues to act strictly as standard Mouse Button 4, ignoring the profile.Here is everything I have checked and done to isolate the issue:Verified that the Macro module is fully installed and up to date under the Synapse 4 "Devices & Modules" management dashboard. Checked active Windows background processes: RzActionSvc (Razer Central Service) and companion engine assets are running normally. Cleared local app configurations by deleting both the %localappdata%\Razer and %appdata%\Razer temporary profile cache folders to resolve any corrupted migration states. Execute

I formatted my PC a few minutes ago and wanted to install Razer Synapse, but when I try to open it, I get an error (RazerSynapseInstaller.err). Inside the folder, it says (Failed to write installer file (Permission denied)).I’m running Windows 11 and have already disabled the firewall and antivirus, but it still isn’t working.I look forward to a reply.

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.

Hi Razer team,I'd like to request support for the Razer Basilisk V3 X HyperSpeed (model RZ01-04870100) in Synapse for Mac.My setup:- Device: Razer Basilisk V3 X HyperSpeed- Model: RZ01-04870100- Mac: MacBook Pro (Apple Silicon)- Synapse for Mac: latest version installed- Connection tested: both HyperSpeed wireless dongle and BluetoothCurrent situation:The mouse works as a basic pointing device, but Synapse for Mac does not detect it. This means I cannot configure:- Side buttons (Mouse 4, Mouse 5)- Middle click- Sensitivity Clutch (third side button)- DPI settings- RGB lighting- On-board profilesI see that Basilisk V3 Pro, V3 35K, and V3 Pro 35K are already supported. Could you please add the V3 X HyperSpeed (RZ01-0487) to the supported devices list as well? It's a current-generation product and many Mac users own it.Thanks for the work on bringing Synapse to macOS — looking forward to broader device support in future updates. 

I was attempting to organize macros into folders and once I click on a folder within a folder the entire macro tab turns grey. It won’t properly show the macro tab again until I close is and reopen it. However, now I cannot see any of the macros I’ve placed into the folders.Before clicking the folder:Here is what it looks like after I click the folder:Please advise on how to fix.

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.

I tested.## SummaryI have identified a fully reproducible regression in Synapse 4 affecting both the Tartarus V2 and Tartarus Pro.When the D-Pad is configured as **8-Way**, pressing any D-Pad direction while **HyperShift** is active causes the D-Pad to ignore its configured bindings and instead generate the default Arrow Key inputs.This issue does **not** occur when the D-Pad is configured as **4-Way**.The exact same hardware and workflow worked correctly in Synapse 3.---## Environment* Windows 11* Synapse Version: **4.0. [removed by moderator] *** Guest Mode (not signed in to a Razer account)* Clean installation using the official Razer Driver Clean-up Tool* Default profile only (no imported or cloud-synchronized profiles)Devices tested:* Tartarus V2* Tartarus ProThe issue is reproducible on both devices.---## Steps to Reproduce1. Install Synapse 4.2. Launch Synapse in Guest Mode.3. Configure the D-Pad as **8-Way**.4. Set **every D-Pad direction** on both the Normal layer and the Hype

Please add support for the Razer Orochi v2 on Razer Synapse for Mac. I would love to be able to control my mouse on my Mac. It would really help me with playing GeForce Now and other games that I need to use the high dpi and other settings that are only available in Synapse like Hypershift.

As the title says, the Chroma Visualizer keeps turning off automatically when I boot my computer back up, which makes me go to the Chroma App and activate it every time I use my system. I also tried reinstalling both the Chroma app and the Synapse app to no avail. If anybody has a fix to this I would be very glad.Thank you in advance.
