Razer Synapse

Dear Razer Team,Hi, I need to know why my mouse is not working. Let’s look at the picture. Do you see extra buttons that the mouse allows to change anything keyblind? It works when the mouse is moving, click and drag, but the extra button won’t work on Synapse 4. However, my mouse works fully on Synapse 3, unlike Synapse 4.Please let me know if you plan to add the list to this mouse or fix it. I’m really disappointed that I used Synapse 4. I hope you will understand this. Thank you.Best regards,keehin2002

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...

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’ve used the Razer skill to set up lighting routines for a couple years.  It suddenly stop working in Synapse3.  Went through the steps of reconnecting the amazon and razer accounts, and it completes as usual but the skill never enables in Alexa.  Installed Synapse4 with same results.

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

im on firmware 1.0.2.0 and my sidetone has a really annoying delay and it sounds badhas anyone found a fix?ive tried things other people tried on different headsets but nothing worked

When using the microphone sidetone option on Synapse, my microphone has what seems like half a second delay, which makes it unusable, sounds like im speaking over myself. And it´s not a hardware issue since when connecting via bluetooth to my phone, the sidetone is perfectly fine. I noticed this first when i changed from Synapse 3 to Synapse 4. I just rolled back to Synapse 3 and the issue is still there. Guess none of the versions work fine. Closing/reinstalling synapse doesn´t fix this issue. And when connecting to my PS5 the sidetone is still as lagged.I also had a problem with my Razer Raptor 27 not being detected on Synapse 4. And i could´nt get the option list for the different THX and EQ modes on the Blackshark for one of my games (PUBG), while the rest showed the options, PUBG had no options to tune EQ or THX profiles.Please fix Synapse 3 before releasing yet another bug infested version...

For many years in synapse 3 I had Excel linked to special profile. After migrating to synapse 4 few months ago I was unable to do so, so had to roll back to S3. Now, few weeks ago I tried S4 again and it worked this time. But today it stopped working. In the linked games tab excel was shown with comment "game not found". I deleted it from the list and tried to re-add it. For some reason when I choose Excel.exe with "brose" menu nothing happens, and it returns to the menu of linked games.That is very frustrating for me, since Excel profile is the most important function in synapse for me.

Hey all, Synapse 4 was working perfectly fine until I decided to give it a refresh by closing it from the system tray. I relaunched it, it automatically updated, and now my laptop (Razer Blade 16 2025) is not being detected. It’s listed as ‘disconnected’ under connected devices.I have uninstalled it, repaired it, performed a windows update, and rebooted my laptop multiple times to no avail.  It seems like a random update to synapse caused this issue, since it was working perfectly fine until I restarted synapse. I use synapse for smart battery charging, etc, so I am kind of reliant on it working properly.  Coming here to see if anyone else is experiencing this issue. 

I am curious, are there plans or any existing workarounds to support the Deathstalker V2 Pro keyboard on macOS (latest version, e.g. macOS Sequoia v15.1.1 at time of this writing)? Looking forward to your replies!  

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.

So I can’t get my Razer naga V2 pro to show up on my synapse for MAC despite being on the supported items list. is this a common issue, or is there something commonly missed in dealing with synapse for macos? 

Hello, i have Kraken Ultimate and yesterday i performed a clean Windows 11 installation on my computer in a attempt to fix the audio issues caused by the latest Razer Synapse update, even after format the computer and install the Windows again and the latest Synapse update from nov 16th i'm still facing audio issues, the quality of audio is good but when i go to watch videios or listen any songs on my computer, they have a little delay from the audio in the start of the video or music, i noticed that this issue is more frequently when i go to watch some videios on the youtube, i hope Razer fix this soon.

USB plugged in and case lights up, both THS and underglow but Synapse won’t recognize it. Tried uninstalling and reinstalling, nothing. Case is listed as supported and even trumpets that fact on product page.Called support, btw, after 8-10 minutes going around and around woman helping me said she’d be right back to walk me through some things then the line went dead. Tried calling back in several times but my number must have been flagged as only ever went to hold music after that, then “heavy call volume” announcement and then disconnected. Incredibly shoddy customer service for “premium” products.

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

Hello. I bought the Kraken V4 X headset. Now I've set everything up and THX spatial audio is working fine, but when I look in BF6 and in the app, I can only select Stereo or THX spatial audio as my profile.But BF6 has other profiles. How can I activate them?

After 6 months of the preview, I have uninstalled the application on macOS. Below is a list of continued issues (that have been reported numerous times on this forum) with no resolution. Application does not run in the system tray. While there is a system tray icon for Synapse, if you “Quit” (CMD+Q) Synapse, to get rid of the window, the system tray icon (and thus background process) quits. If the window is closed, then it should disappear from the “ALT-TAB” window listing and run like every other macOS app that has a system tray icon. Razer Naga V2 Support The only way my custom keybinds work is to close the synapse app compltelty. When open, my side buttons do not execute the action assigned in the profile. So in order to modify and test it I need to open syanpse, modify the profile, quit Synapse, test the key bind. Keys sticking Of you alt tab out of your current application while also pressing a c

I am using the Razer Blackwidow V4 low-profile TKL keyboard and the Synapse 4 software. When I try to allocate the hypershift-function to a custom key the hypershift option does not appear (I have seen videos on YouTube with other keyboard, where the hypershift option (arrow) appears when clicking on a custom key). So right now, the only way to activate Hypershift is the FN key, which is too far away for my purposes. I want to use the CapsLock key to trigger hypershift. Can we expect to get this functionality in future Synapse and/or keyboard firmware updates? This is actually an essential function I need to have using this keyboard.

Hypershift still does not work on Synapse 4 for my Deathadder V3 pro. It does work on my Huntsman kayboard. The only way to make it work on my mouse is to close down synapse completely then it starts to work again. I’ve been reporting this for around a year now please get it sorted or I will be forced to switch eco systems where I know the features I need work properly.

Hi.Probably all know that macro on synapse 4 not working the same as in synapse 3.I just created support ticket and report an issue, this will be probably the most curved road but maybe I will handle that.I notice that macro from synapse 3 moved to synapse 4 is played once even if option is set “play while assigned key is pressed”There is an option to set a loop for but if I add this option I give a information in synapse 4 that’s it required razer synapse…I have walkaround but it’s impacting on lighting on all your razer devices which might be dangerous for them.When I have installed both synapses - 3 and 4, Im able to use macro from synapse 3 and lighting from synapse 4 but there is some sort of glitch on the lighting, its turning off for a second randomly. If someone will use this walkaround you are using on your own risk.I will update the thread when I will have some information from

The THX Game Profiles just don’t work at all, first there’s no games or apps recognized automatically, second when I try to add a executable and confirm it literally does nothing a the list continues empty, I just upgraded to windows 11 and the issue also happened in windows 10, so reinstalling synapse don’t work, pls help

How to close a topic or Mark a question as solved? 

After upping to Synapse 4 and buttons not working and uninstalling and reinstalling and sending support logs I decided to go back to Synapse 3.  Did the full uninstall according to the Razer webpage and lots of restarts. Reinstalled Synapse 3 and could not get my NAGA Hyperspeed recoginized, the Tartus was.  I finally got it recognized and tried some macros and they do not work. Tried to go to the Macro module and click on it the header buttono and nothing.  Go to the Modules window and it’s there as an installed module.  Try to go to it from an actual key assignment, the “Manage Macros” button and again it clicks but nothing, it does show the word “Marco” in the grey strip at the bottom.   Any ideas? Win 10. All latest versions of everything.
