# ISSUE: Very Slow Launch When Brave is NOT Running I am experiencing the same exact issue as reported here: > [@Slow launch when no instances of Brave are running](https://community.brave.app/t/slow-launch-when-no-instances-of-brave-are-running/83155): > > Description of the issue: Every time I start up Brave when there are not instances of Brave active it takes about ~25 seconds to launch. When there is already an instance running Brave is running smoothly (new tabs etc.), it only happens on startup. \*\*Steps to Reproduce (add as many as necessary): Close every instance of Brave (or reboot the System) Launch Brave Actual Result (gifs and screenshots are welcome!): The app is launched after 26 seconds. Expected result: Launch the app within… > Description of the issue: > Every time I start up Brave when there are not instances of Brave active it takes about ~25 seconds to launch. When there is already an instance running Brave is running smoothly (new tabs etc.), it only happens on startup. ### Differences with my setup 1. I’m running the latest version of Brave: Brave Browser 78.1.0.1 (100.1) 2. I’m running macOS 10.14.6 (Mojave) 3. It takes ~20 seconds before Brave is fully loaded. 4. ALL extensions are **disabled**. ### This is totally unacceptable 1. This issue has been reported for months 2. It does NOT occur with Google Chrome, Vlvaldi, or any other Chromuin-based browser 3. It makes Brave Browser unusable So, until it is fixed, I am switching to Vivaldi, and maybe I’ll find I even like it better. Thanks for your prompt attention to this issue. ---

Yes, it did NOT help, just as it did NOT in all of the other cases. This is NOT an issue with me or my Mac. It is an issue with Brave Browser. Please investigate. ---

I’m having the same problem. When the scanner is turned on, it slows down as if loading something. I think Brave sync or Brave adblock is causing it. ---

@JMichaelTX, If your device is part of a Sync chain, go to `Menu --> Sync --> Leave Sync chain`. If not, try launching the browser from the macOS Terminal with the `--disable-brave-sync` flag. The full command would be (in terminal window): `open -a Brave-Browser.app --disable-brave-sync` ---

@JMichaelTX, You don’t see this option at the bottom of the page? ![image](https://global.discourse-cdn.com/brave/original/3X/e/6/e684b9fcf339827a24f4dcb8d101c045ebfdd22f.jpeg) Also sorry about the Terminal command, it should actually be: `/Applications/Brave\ Browser.app/Contents/MacOS/Brave\ Browser --disable-brave-sync` ---
