Razer Synapse

I ordered the new Razer Naga V3 Pro, and it showed up yesterday.I was disheartened to see that it's not recognized in the Razer Synapse for Mac software (Version 4.0. [removed by moderator] ).So I decided to use a technique that I've used with previous Razer mice that have onboard memory.I'm posting this here on the chance that it helps some of you.The only major downside is that you need access to a Windows machine that can run the current Razer Synapse software. Luckily, I have an old laptop that works great for this.Connect the Razer Naga V3 Pro to the Windows machine.Install/open the Synapse software on that Windows machine.Use Synapse to configure all of the mouse buttons, scroll wheel & tracking options.These settings will automatically be saved to the onboard memory of the Razer Naga V3 Pro.Connect the mouse to your Mac and all of your settings should be present and functioning natively.A bonus discovery that I made yesterday: I have discovered that you can use the Windows k

Hey, Razer PLEASE add support for the DeathAdder essential mouse on Synapse for Mac Preview. Thanks!Love you!

Hi everyone,A few weeks ago (I believe right after a Windows update), I started noticing brief mouse "stutters" during the first minutes after startup — it would happen once or twice, then stop, with no crash. I had never experienced this before.A few days ago, this escalated: the mouse stuttered, then both my monitors went completely black and the system became fully unresponsive — mouse frozen, no input at all. I had to force a shutdown via the power button.I checked Event Viewer afterward and found a Kernel-Power Event ID 41 (Critical) with BugcheckCode 0, meaning no clean BSOD or crash dump was written — just a full hard freeze. I also ran a complete hardware diagnostic (UserDiag) right after: 0 WHEA errors, 0 incidents, everything nominal on temps/voltages/components. So the hardware looks completely healthy.I'm on Windows 11 25H2, using a Razer DeathAdder with Synapse. I just did a full clean uninstall/reinstall of Synapse (using the official CleanupRazerDrivers tool) to see if i

I was using synapse 3, although it can’t open for long time, the profile still works. Then i upgrade it to synapse 4, the profile not work.Is there any way to reinstall working synapse 3 to export the profile or get the synapse 3 cloud backup profile?I cant find a working synapse 3 installer, and the one i have says cant connect to server :(

DId this update change anything in the Razer Chroma API?I may not be wording it correctly, but my issue is several of the devices I was lighting in my development project have suddenly stopped working.I am using Razer Chroma SDK for Unity installed from https://github.com/WyvrnOfficial/Unity_ChromaSDK.git and all WAS working well until this update.. Now I am only getting lights on mousepad, mouse and mouse dock. Keyboard, Seiren, Tartarus, Aether strip have all stopped responding to requests to light up.I think the problem might be in ChromaAnimationAPI, specifically ChromaAnimationAPI.SetEffectCustom2D(int device, int[ ] colors) is no longer working.To be clear, I’m not asking if the github repo changed, I'm asking about the underlying chroma service that this github repo would be interacting with.Can anyone confirm if this update changed this API?Is anyone else suddenly having issues using this API or lighting some devices?

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

I ran into an issue with Razer Synapse 4 not showing wireless battery percentage for 2 different wireless models. Both are listed as officially supported and backwards compatible with Synapse 3 and both had the same exact issue with no battery percentage displaying. I uninstalled Synapse 4 and reinstalled Synapse 3. BAM! I can now see all wireless mouse battery percentages. I attempted to troubleshoot with support but it took way too long to get valuable responses and I’m not interested in downloading a software log capture tool. Will check out Synapse 4 at a later date perhaps.I thought I’d post this for anyone who has a similar problem as all of the threads I’ve seen are requesting PM’s and don’t show a resolution status or troubleshooting steps.

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. 

Hi Razer, I recently bought your wolverine v3 TE 8k, i love this controller a lot, but i find the software very limited. I used to be able to apply anti-dead zone settings to my controller to counter the fairly high dead zone in older games, as well as customize the aiming curve using Bézier curves, for example. Unfortunately, your software doesn't offer all these options, including the ability to adjust the dead zone more precisely, in increments of 1 instead of 3, as was possible with the Vader 5 Pro software. I think implementing this in your software would greatly improve its quality and credibility with many gamers. It would also offer a complete controller experience (which is excellent) that I unfortunately find somewhat hampered by the software, or at least not used to its full potential.Thank you for your attention !! 

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

After a recent update Synapse and Chroma the backlight on the device stopped working (only in visualizer). Everything else is working:I believe this is some kind of bug in the code.Has anyone encountered the same problem?

Hi,I’m having a persistent microphone issue with my Razer BlackShark V2 HyperSpeed when using Razer Synapse 4 on Windows.Environment Headset: Razer BlackShark V2 HyperSpeed (wireless dongle, 2.4 GHz) Software: Razer Synapse 4 (latest version as of today) OS: Windows 11 (fully updated) Connection: Dongle plugged directly into the PC (rear USB port) Default input device in Windows: “Microphone (Razer BlackShark V2 HS 2.4)” Issue summaryWhen Synapse 4 is running, using the physical mic mute button on the headset causes my microphone input volume to be forced to 0 and it stays at 0 even after unmuting. In Synapse 4, on the “Mic” tab, the mic toggle switches ON/OFF correctly, but the mic input level slider stays locked at 0 after I mute once. In Windows sound settings, the input device is set correctly and the volume is normally at around 80. After the issue occurs, the Windows input volume also drops to 0 and stays there, as shown in the screenshots. Because of this, even when

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

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.

I was wondering if razer is planning to add their V3 pro to synapse web driver support anytime soon. looking forward to try it :D

Given the BIG AMOUNT of problems that synapse 4 has, specially with my Tartarus pro, I mistankely trusted on the new version Synapse 4 and now I MUST return to synapse 3 to preserve my previous functionality, how can I return to that version? I cannot see a place to download synapse 3 installer for windows, any ideas?

Razer Synapse not connected to the internet even though my computer is. That is making my mouse's macros not work. Of course it is hard to know for certain if that is the case but I don’t see anything else being wrong.

I’m experiencing an issue with my BlackShark V3 Pro after performing a firmware update through Razer Synapse.After the update:The USB dongle no longer lights up The dongle is not detected by my PC There is no audio when using wireless modeHowever:The headset still works normally when connected via USB (wired mode)I have already tried the following:Using different USB ports Restarting my PC Reinstalling Razer Synapse Attempting to re-pair the headsetThe issue started immediately after the firmware update, and it seems the dongle may have failed during the process.What can I do?Thank you.
