in Installation by
I am using MacOSX Catalina.
I dragged "InstallMGTools_WrittenByMiguel.mel" and dropped it into the Maya viewport.
I then click my way to "Install", and then things start loading, but halfway through a message pops saying it can't be installed as the source isn't verified.

This has been fixed and is available for download here

Starting from MGTools_Release_MacOS.v3.5.releaseDate2022-05-17, the plug-in bundle files have been notarized by Apple.

But due to the nature of the Maya plugin .bundle extension as it is used as an executable Mach-O file, the notary ticket cannot be stapled, so when you install the tool, make sure your machine is connected to the internet so that the macOS gatekeeper will go online to check the notary and cache it. This is a one-off process, and all you need to do is if the gatekeeper warns if you want to load the downloaded .bundle file, press the "Yes" button.



I have released the dmg format for the macOS package. It is notarized and stapled, so even if it is offline, the user should be able to install it without any problem.

Same download entry here.

MGTools can run in osX Catalina.
It is just MacOSX Catalina started to force every app or plugin developer to sign up to Apple as a developer, and have their app and plugin notarized by Apple.
The overall process is not easy (and not free), in the long run, I will manage to get that done, but before that, please follow this one-off process to make it work.

Ps. I missed the chance to snapshot for MGTools Plugin, so I tried it on the bundle plugins of cam2dViewer just to demonstrate the process. So in the user machine, it will be "MGTools_2020x64.bundle" instead of "cam2dViewer_2020x64.bundle" in each pop-up dialog. 

  • When you install MGTools, a dialog will pop up which is similar to the pic as shown below:

  • Click cancel and close the installation dialog, no need to exit Maya. 
  • Go to Security & Privacy in Preferences:

  • Go to General, it will show the bundle was blocked.
  • Click the lock button at the left of "Click the lock to make changes" label.
  • Enter the password to unlock the settings to allow the change.
  • Click the "Allow Anyway"
  • Go back to Maya, drag and drop the InstallMGTools_WrittenByMiguel.mel to start the installation again.
  • This time, it will still pop up a dialog, but with an extra "Open" option:

  • Click the "Open" button and the installation will go on.

Unfortunately, you have to repeat the rough process for all 4 MGTools bundle plugins: MGTools, animRescue, cam2dViewer and MGautoSave, same when you a new MGTools version that changes these plugins. sad


If when you try to launch the app, the dialog popped up was different, like this:

Then you follow this ANSWER.

The workaround are no longer needed as the new release has been apple-notarized.
