Matlab 2023b Apple Silicon每次打开都需要重新登陆

Matlab 2023b Apple Silicon每次打开都需要登陆，有一个这样的弹窗提示：无法保存登陆信息。您当前已登陆，但下次启动此应用程序时会提示您再次登陆，不知道是怎么回事？在linux上没有遇到这一问题。

Approximate translation:

Matlab 2023b Apple Silicon needs to log in every time it is opened. There is a pop-up window prompting: Unable to save login information. You are currently logged in, but the next time you launch this application, you will be prompted to log in again. What's going on? I haven't encountered this problem on linux.

[波]

我也遇到了一样的问题，请问你解决了嘛，我重装了matlab还是有这个问题

Hi Sheng,

If this error occurs when attempting to start MATLAB, there is a possibility of conflict between the MATLABConnector ServiceHost and the MathWorks Service Host.

A possible way to resolve this is to reinstall MathWorks Service Host, please refer the following answer thread to know how to uninstall and reinstall MathWorks Service Host:

https://www.mathworks.com/matlabcentral/answers/1815365

 

If this does not work, please try resetting your local credentials with the following steps:

• Shutdown any running MATLABs, MathWorksServiceHost and MATLABConnector processes.
• Delete their credentials storage folder. It can be found at the following path in MAC OS:

"~/Library/Application Support/MathWorks/credentials"

• Try running MATLAB again.  

If this error occurs when attempting to start up MATLAB Drive Connector on macOS, there may be an issue with the secrets file contained with the credentials directory, which may have been deleted or modified. To resolve this issue with secrets file refer the following steps:

• Delete the following directory: /Users/$USER/Library/Application Support/MathWorks/credentials
• Delete the "MathWorks Key" key found in your login keychain in the Keychain Access app under UtilitiesRestart MATLAB Drive Connector.

Hope it helps!

我的是Windows系统，按照操作重装了MathWorks Service Host，没有用，打开Matlab 2023b时依然提示“无法保存登录信息”，每次都需要重新登录，不知道credentials storage folder在Windows系统中的哪里

因为这个目录 AppData\Roaming\MathWorks\MATLAB 缺一个R2023b_licenses文件夹（里面是license）才每次都要登录的，如果你之前安装过的话把之前文件夹的名字改成这个就行啦

厉害的

[康健]

请问这个文件在哪儿找啊

[Frankie]

感谢感谢！

感谢！

问的是apple silicon, macOS版本; 你这个目录是windows

[Chengxi]

很对

我自己笔电装的是matlab 2025b，学校买的正版的，在重启之前，登录一次之后，出现图中的提示，关掉MATLAB，然后再次打开，没有提升需要再登录，能打开。但是电脑关机重启后，再次打开MATLAB，仍然会出这样这样的提示。我在其他电脑上尝试装过这个版本，打开软件能登录，也没有出现无法保存登录信息的提示，但是在有关文件目录下，也没有找到相应的R2025b_licenses文件夹，也能正常启动使用，电脑重启再打开也不会。就很奇怪了！

我用的win11和2025a，把APPDATA%\MathWorks\credentials删了，不行。然后建了一个AppData\Roaming\MathWorks\MATLAB\R2025a_licenses，虽然并没有在里面生成任何东西，但是真的不会报错了，能记住登录状态了
