After installing sage-9.0-OSX_10.15.2-x86_64.app.dmg, doubling clicking the Sage icon immediately results in a window popping up with the message: "Jupiter Server fails to start. For some reason the Jupiter server ailed to start. Please check the log for clues, and have that information handy when asking for help." The log shows:

Rewriting paths for your new installation directory
===================================================

This might take a few minutes but only has to be done once.


(Indeed, log ends in "patching /Applications/SageMath-9.0.app/Contents/Resources/sa").

I confirm that Jupyter does not start. My log shows the following output

Try running the following commands in a terminal:
    
    APP=/Applications/SageMath-9.0.app
    xattr -dr com.apple.quarantine $APP

If it says you don't have the permissions for that,
try the same with "sudo" as follows:

    APP=/Applications/SageMath-9.0.app
    sudo xattr -dr com.apple.quarantine $APP

I separately reported the same behavior -- the Jupyter server not starting with SageMath-9.0 -- and so tried the suggestion of 

APP=/Applications/SageMath-9.0.app 

xattr -dr com.apple.quarantine $APP


reportedthe latter both as shown and with "sudo". 


This does not fix the problem!

I also gave Sage Full Disk Access (in Security -> Privacy preference pane), as well as using xattr, as it seemed unable to access certain directories.
 
Sage now does start Jupyter.

Same behaviour, with the same log, also after giving Sage Full Disk Access as suggested by Ralf Martin.

Giving SageMath-9.0 full disk access works for me, too.

It seems like a rather blunt solution for getting around Catalina's increased security!

Is it full disk access that's really required? Or just the ability to launch a terminal process?

Same as Martin for me too...

There is more to it: after doing all of the above, plus removing both ~/.sage and org.sagemath.Sage.plist, the jupyter did start. Unfortunately I don't know if the critical step in my case was the removal of ~/.sage or of the plist file.

I did not have ~/.sage. Removed org.sagemath.Sage.plist, but no difference for me.

I have the same problem and log as Martin. After giving Sage Full Disk Access as well as using xattr and sudo, it still does work.

Is there any other way to launch it?

maybe trying the terminal version:
http://www.mirrorservice.org/sites/www.sagemath.org/osx/intel/sage-9.0-OSX_10.15.2-x86_64.tar.bz2

is a better idea. After the installation, one can
run, in terminal, in the place where you have it installed,

./sage -n

to launch Jupyter

I had the same problem as the OP. Jupyter Server would not start after install of the .app.dmg package. 

I can report success launching Sage from the Applications icon after the following steps:

1) Grant Full Disk Access in System Preferences->Security->Privacy (as suggested previously)

2) Launch Sage from the command line in the executable's installed directory. In a terminal window:

cd /Applications/SageMath-9.0.app
./sage -n



3) The executable should "patch" or rewrite all of the required paths to match their actual locations in your particular Catalina install. 
    After that, it should open a Jupyter tab in Safari.

4) When you see the Jupyter tab in Safari: 
     click the Quit button. This will stop the Jupyter Server, but that's ok. 

5) Launch Sage using Applications->SageMath-9.0. 

All should be well at this point, but your actual mileage may vary. Hope this helps.

I had the same problems and it worked only after following Dan Brooks suggestion. Note that I could launch the jupyter server with MathSage working properly through the terminal with sage -n jupyter. Only launching through the MathSage icon was not working and was leading to the message reported by Eric Martin.
