@yuanshizhan , try to watch those cases. but if you still have the problem you can ask us down below.

[elijahtsai]

also, the password is your login password, but you need to choose "Always allow" to prevent it keeps asking you multiple time.

hi

@yuanshizhan , try to watch those cases. but if you still have the problem you can ask us down below.

hi the answers in other issues didn't quite help. I tried deleting the the sketch.app in /Application, and use ./sketchcrapp.sh -m but got the following errors.
Downloading sketch manually and unzipping the install file give me the same error as before.

$$$ ./sketchcrapp.sh -m

Hi @yuanshizhan ,
I've fixed the problem in magic function. Can you re-download our script from our repository and try again with same command ./sketchcrapp.sh -m and according to the description, I assume the window you seem is like the following image.

Remember the password is your login password, and don't forget to press the "Always Allow" button.

[yuanshizhan]

hi thanks for answeriing! I followed your insturction, and it ran successfully, but when I tried opening Sketch app either in Application or launchpad, nothing happens, not even the prompt saying the app can't be open. It only showed me that prompt when i tried opening sketch in spotlight search. Any idea why this would happen?

[yuanshizhan]

and ono top of that, im not really sure how to go to Settings -› Security and allow opening Sketch.app application.. I went to the Security & Privacy tab, and dont really know what to do there.

[elijahtsai]

@yuanshizhan I really don’t think the script has this many unseen problem in order to patch your sketch, can you tell me your OS version and sketch version and post entire debug message in your terminal here(included whatever command you type in), I really need to make sure the patch process in your OS environment was successfully completed.

[yuanshizhan]

OS: macOS Catalina Version 10.15.7

SketchCrapp process completed. Sketch.app has been patched :)

I don't see anything wrong with the SketchCrapp. It should work as-is (patched).

[elijahtsai]

@yuanshizhan , there is a problem in your keychain, the script couldn’t sign the sketch with exist “sketchcrapp” self-sign certificate, since this is not script side error, you should figure it out by your self. but if there have many people meet the same problem as yours, we can reopen the issue and start the investigation anytime, I agree with @duraki decision to close the issue.
