SEGGER Embedded Studio multiple instances on OSx Catalina

[lbe]

Hello everyone,

I already posted this on the Segger Forum, but rarely I get answers there, so I hope someone have a solution to this hellish problem!

I have been happily using SES for a few years now to work on Nordic devices (NRF52). So far I worked in a Linux environment, and I used to open a few projects at the same time to copy code fragments or to compare source codes in case of problems.
I recently switched an a MAC running OSx Catalina, and I am not able to open more than a single project....whenever I have an open project, if I try to open a new one, the latter is opened in the existing windows so there is no way for me to have 2 (or more) projects side by side.
I already tried activating the proper option in the SES options (Tools-->Options-->Environment--> Allow Multiple SEGGER....), as suggested in other threads (or as I did in Linux), but this does not seem to have any effect. I tried to put the option both to YES or NO (to check if there was maybe a mistake there), but still I can open only a single project.
This is pretty annoying especially when I have to check for project settings, included files, source code and so on, so it would be great if someone can suggest me a possible solution to this issue.
These are the details of the SES version I am running


SEGGER Embedded Studio for ARM
Release 4.30a Build 2019110506.40491
macOS x64

Thanks for the help!

Hi.

I haven't seen this problem before.

As you haven't gotten a response on the Segger forum yet, I'll take a look and see if I can find some more information about this.

I won't have access to a macbook to test this before monday, so I'll need to get back to you then. Meanwhile I'll ask around if someone have seen this before.

Best regards,
Joakim Jakobsen

To open a new instance of an App on OSX, open the terminal and enter the following at the prompt:

open -n /Applications/YourApp.app

Hello,

thanks, this is somehow what I did. I created an alias in my bash profile so that whenever I write "ses" it opens the studio from the command line with the -permit-multiple-studio-instances option, just in case.

I would still prefer an easier solution, like double-clicking on the .emStudio file as I used to do before, but for the moment I can live with this workaround. I'll wait for an answer from Joakim, if he can propose a better solution before closing the discussion.

The -n is important force new instance.  Without that is will just send you to the currently opened one.  It is the default behaviour of OSX.

Hi again. 

I talked to SEGGER about this. They are aware of the issue and are working on a fix. 

From what I understood this issue was introduced in Catalina due to some access right management.
The only current workaround is to either run different versions of SES or open a new instance of SES using "open -n". 

Best regards, 
Joakim
