Razer Synapse

i want to test signalrgb for some time and also keep synapse running. how can i remove light control from synapse ?

Are there any plans for Synapse 4 or 3 to be ported to Mac OS? I am planning on buying another Razer mouse and keyboard to be used with my MacBook but the lack of synapse is something that worries me.

Linked Games and Auto Profile Switch no longer works after an Synapse Update (Jan 2026), profile switch doesn't affect the apps i'm using. i did a clean install to the software, the linked games now takes forever to scan games and i can't even add programs to it.

A few days ago I was prompted to update Synapse, including a reboot for a driver update, if I’m remembering it correctly. Later, when I went to play a particular game through Steam, it started immediately crashing on launch. After trying several things to fix it, I remembered the Razer update. After quitting out of the Synapse app, the game launched without issue.Going through my library, I found four games that crash immediately on launch when Synapse is running (with or without any devices connected) but work fine if it’s not. The games that are crashing are Epistory, Kind Words, Kind Words 2, and Squeakross, and the only thing I can find in common between them is that they’re all built with Unity, but other Unity games I tried work fine.[I’m on an M1 MacBook Air running macOS 26.2 and Synapse for Mac 4.0.86.2601140839 with a Basilisk V3 Pro.]On a positive note, hiding Synapse from the Dock finally works! Yay!

Whenever my mouse is inactive for a short period, and I then move it, the light turns on green, then turns red after a second, then back off. I have all the lighting options set to “off”.

Hi, I would like to create a macro (or an other way if possible) to have shift + scroll click pressed down as long as I am pressing the mouse button that is assigned this macro. I would use this to pan around in blender and other 3D programs. But at the moment I am only able to have this key combo loop (shift down - scroll click down - shift up - scroll click up looping constantly) when keeping the button pressed, which results in stuttery behavior. Is this at all possible to do this? Sincerely I have a Naga 2 Pro mouse

Hi,yesterdays I shutdown my computer and an error happened related to Razer Synapse.Now the program won’t start.Tried unistalling and re-installing. Error remains.

Queria entender porque o Chroma não reconhece o meu mouse razer se o synapse 4  reconhece

Hi,I have a suggestion regarding the Razer Synapse software concerning macros.It would be great if we could add an action to switch the DPI directly in a macro (to decrease or increase the DPI level relative to the DPI levels set in the mouse settings).This is a feature I appreciate on my Logitech mice, and I would love to have the same feature on my Razer mice.Thank you for your support.

Razer please bless us with the ability to switch DPI with macros

How do i get my left click to work as intended? i cant get my left click to work, no matter what i sign it too. why cant it be simpel as other mouse’s. its stupid to not be able to use left click without anny fuss.

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.

Hi,Have an issue where my mouse's (Naga) extra buttons get pressed continuously until it's disconnected from my computer, then after that, the whole auto profile switching goes out the windows, this is all happening after the latest update. This is across multiple devices, as on my Firefly V2 Pro, if mouse gets plugged into the mousepad USB port, it starts to work intermittently when it was fine a week ago.Can we get a fix for this and a way to stop future updates?Thanks in advance.

Hey everyone,First off, big thanks to the Razer team for finally bringing Synapse to macOS.I recently bought several Razer products, but I just realized that not all of them are currently supported in the Synapse for macOS. Here’s what I’m using on my setup:MacBook Pro M3 (macOS 15.5)Kiyo Pro Webcam (RZ19-0364)Seiren V3 Chroma (RZ19-0506)Goliathus Chroma Extended Mousepad (RZ02-025003)BlackShark V2 X (RZ04-0324)Basilisk V3 Mouse (RZ01-04000)BlackWidow V4 Keyboard (RZ03-0469) I really hope these devices will be supported very soon as well.  Thanks.

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

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.
