) has brought increased security settings that may prevent the loading of unsigned 3rd party externals. On Mac OS 10.15, when a file like this is downloaded from the web, it is marked with 

 via extended file attributes (xattrs), which then prevents loading in Max. The longer term solution will be for third party developers to sign their externals, however there are many safe-to-use externals that are no longer in active development, but still relied on by many. In the meantime, there are several workarounds that can be used. All of these options involve bypassing Apple’s security infrastructure, so make sure you have downloaded the externals from a trusted source.

The current best option is to run Terminal’s ‘xattr’ utility using the ‘-d’ option to remove the ‘com.apple.quarantine’ xattr entirely. Open the Terminal utility and type:

xattr -d com.apple.quarantine [path/to/extern.mxo]

If you have a number of externals that you wish to perform this on, you can use the ‘-r’ option to the xattr command, which acts recursively on a directory or bundle. Open the Terminal utility and type:

xattr -d -r com.apple.quarantine [path/to/extern/directory]

In an upcoming version of Max, we hope to add better notification when the com.apple.quarantine xattr is present on a file that Max attempts to load, and will be exploring other options for improvements in this area.

Please note that the "right-click" to overcome Gatekeeper no longer appears to work on 10.15+.

This is not working I've tried several times and still have program error thtis is the error list, what can I do?

Has anyone had this work on their Catalina machines? It hasn't worked on mine either. Thank you.

You can pull the mxo. file into the terminal )

截圖 2020-02-24 19.45.04.png

Open the Terminal utility and type:
sudo xattr -rd com.apple.quarantine / Your software path.app（You can  pull the mxo. file  into the terminal )

xattr: /Users/josemanuelberenguer/Documents/Max 8/Library/iCube_Max-410_macos: No such xattr: com.apple.quarantine

Pulling the .mxo file into the terminal itself did the trick, thank you!

Terminal seems to complete the command but I still get an error loading externals. Any suggestions?

How do I pull the .mxo file into the terminal? Thanks!!

Drag the object into the terminal window. It will show you the right path.

Thanks a lot MP the thingis that I can’t find the object or .mxo file in my Mac anywhere. I had already deactivated the quarantine in my Macbook and the Max 8 app is opening fine, but when I try to open it in Ableton through Preferences->File/Folder->Max app my Ableton closes/crashes instantly. I don’t know if it’s still because of Catalina

Hello... I've sucessfully used the xattr -d and xattr -d -r commands to cancel the quarantine flag of some third party externals or folders. Nevertheless, some of them (as "shell" external, revised some years ago by Jeremy Bernstein) resists this command and max refuses to load them due to security policy. This is because I tried xatter -c. It works when Max is open during the execution on the terminal. If max is closed, when opening it after the execution of the command, max doesn't accept to instantiate shell. The quarantine atribute seems hasn't been completely removed.

Any Ideas about what to do in such cases? Many thanks!

After trying individual to remove the quarantine on individual files I took the nuclear option. This cleared up everything for me:

sudo xattr -rd com.apple.quarantine /Applications/Max.app/Contents

Many thanks ... Tried it. Unfortunately it does not apply to "shell" in my system ....

Bummer. I'd experiment with running the command on increasingly higher directories containing those files.

you have to run that command on the directory where your shell external is stored. shell is not a factory external, and therefore won't be in the Max app, but in some other directory in your Max search path.

Max 8.1.2 was working fine. I just updated to 8.1.3 and now I'm getting a bunch of errors (see attached). If this was a catalina issue, shouldn't I have seen this issue with 8.1.2 as well?

I tried the nuclear option as described above and that worked for me as well.

screenshot_4071.png

I have tried everything now but it does not work there is someone who can explain to me exactly which commands I have to execute in the terminal of Catalina

sudo xattr -rd com.apple.quarantine add space at the end !

xattributes in the current user directory.

there is nothing wrong removing ALL xattributes from the user directory

Permanent freedom from apple restrictions would be to

deactivate SIP and disable gatekeeper all together

and finally stop updating system if it's not really necessary.

in terminal type:
sudo xattr -rd com.apple.quarantine    add space at the end !
drop directory to remove com.apple.quarantine
hit enter, type admin password, enter.
or type :
sudo xattr -rd com.apple.quarantine ~/
hit enter, type admin password, enter.
that would wipe all com.apple.quarantine xattributes in the current user directory.

My experience is similar to Source Audio's. But I don't clear all xattr for the home directory, only the files/folders that I need... For instance, an AU or VST plugin that hasn't been updated residing in /Library/Audio/Plugins...

sudo xattr -cr "and drop the offending folder/file"

It clears all xattributes recursively and usually works.

I also disable SIP (System Integrity Protection). I'm still on Mojave (and for the foreseeable future).

I understand the need for security but Apple's tendency lately in this regard has been too much...

I would advise against running the command on everything in your user (~/) directory. These security measures are in place for a reason. I agree with Pedro to only perform this action against files and directories that need it.

Dietmar, can you share screenshots or log messages so we can help?

Thank you for your answer, yes I cannot work with the patch because Catalina's security settings do not allow it. I have MacOS Catalina version 10.15.3

One of these two commands should work for you depending on where you installed Max:

sudo xattr -rd com.apple.quarantine /Applications/Max.app/

sudo xattr -rd com.apple.quarantine ~/Applications/Max.app/

Can you run both of them in the terminal and share the output?

there should be absolutely no need to run xattr on the Max app itself. instead you should run xattr on the folder that contains the 3rd party externals that you are trying to load. if it's a package, especially one that contains support libraries, run it on the entire package folder.

If you've put the orchidea in the Packages folder, it should be something like this:

sudo xattr -cr /Users/"You"/Documents/Max\ 8/Packages/orchidea

If you've put the orchidea in the Packages folder, it should be something like this:
sudo xattr -cr /Users/"You"/Documents/Max\ 8/Packages/orchidea

Thank you for your support but I solved the problem. I had an apple antivirus scanner that I deleted, everything works fine now. Maybe this is also a possible solution for all who have similar problems)

I'm getting the same issues and nothing here is working for me. Any other ideas?

It seems to me that your sigmund~object does not match your Max version. I Belice this has nothing to do with Catalina Security policies.

That might be the issue, it worked for my professor who is still on 8.1.0, and I'm on 8.1.3. Is there a way to "revert" back to an earlier version of Max to see if that would work?

Hi. I am having the same problem with the latest version of fiddle from here (https://github.com/v7b1/fiddle_64bit_version/releases). It was working all fine on Catalina until I upgraded to Max 8.1.3. I have tried everything including going back to 8.1.2 but no luck. It seems to be a real issue for many Max users using "unsigned" externals. Any help appreciated.

I still cannot run a basic external (RTC library)... I've tryied everything you've mentioned without results... can anyone give me a help? :)

FWIW, I'm getting this error on jit.gl.syphon after a fresh update in the Package Manager and I'm NOT running Catalina, but 10.14.6 Mojave. Max 8.1.3.

Quick followup: turned out Max didn't yet have access to the camera in the Security: Privacy settings. Once I instantiated a jit.grab and gave it permission, jit.gl.syphonserver was also able to instantiate.

With Max 8.1.3 it's helpful that the name of the external causing the error is printed in the console. I do wish it showed the full path to the external though. That would be similar to the "you have multiple files in your search path" conflict messages that include full path names.

(I had installed some externals for both Max 7 and Max 8 and initially removed the com.apple.quarantine xattr from the ones being read in the Max 7 path, which, as you might suppose, did not improve life when using Max 8.)

The Shell External don't work in my max after the Catalina update.

Hey Guys, I have the same problem encountered by JOSÉ MANUEL BERENGUER.

Hey All,
I encountered the same problem as JOSÉ MANUEL BERENGUER  with the Shell object in max8.1.3  after the Catalina update.

JOSÉ MANUEL BERENGUER: did you find a solution to the problem?

Dear Fabrizio Saiu : No. I didn't. I was considering try with Node.js. The problem is that with Node.js any code will only work in Max 8...

You must absolutely avoid installing this update because the external ones will be blocked again.

Thanks José! 
I downgraded to high Sierra...
But, be careful!

This is really annoying. None of the above mentioned workarounds functions .... 

I was having this issue when I was using my Documents directory which I have syncing to iCloud. When I made a new directory outside of Documents and pointed my File Preferences to the new directory, everything worked just fine.

Be careful if you directly copy projects or mxo builds over from the Documents folder though because it may still not work then.

Thank you Source Audio for your help, I have another question , I am not sure where to place the actual .mxo file ? like does it have to go in a specific folder ? I am using MAX 8

Thanks, Source Audio, I am new to MAX, and could anyone help me with theinstallation of this external object into max 8 ? I am not sure should I download all 3 or just the top one ? and which folder they need to be placed?

Screen Shot 2020-08-27 at 11.29.54 pm.png

if you download that top one and extract it, you'll get external.

You can place it anywhere in Max search path,

but maybe best place would be to replace 32 bit external

From the screenshot it is in your Documents/Max 8/Library.

thank you Source Audio , do i still have to use sudo xattr ?? and which version of it is useful ?

It will not harm to remove any xattr from that external.

 (add space at the end) into terminal and drop it, hit enter.

So there is no info I could read about what device this external is supposed to support.

in terminal type "sudo xattr -d com.apple.quarantine [path-to-external]"

but instead of typing your path in by hand, drag the external directly into the terminal window(just after the space you type which follows 'com.apple.quarantine')...this will insure you have the correct path, and then enter your admin password(for 'sudo' operations("super user do") requires admin level permission).

i just tried the above exact method on the .mxo zip download found here:

it works for me(alternately, when i first tried dragging the external onto Max icon to load it without removing quarantine, Max itself asked if i'd like it to try to remove the quarantine, i told it to 'proceed' and it worked... maybe something new as of Max8.1.7? but then after deleting the external,redownloading,reloading,etc. to check if i can reproduce the same success, MacOSX now intercepts before Max can even do anything and I have to use the terminal method again from now on 😂)

[Edit: the article said this wouldn't work, but i just upgraded to 10.15.7 and it does seem to work for me]

oh, i just found another way around this:

1) right-click on the external to choose from the contextual MacOSX/Finder menu to open with Max

Screen Shot 2020-10-21 at 9.34.24 PM.png

2) (if this second step doesn't show the following window, try hitting 'cancel' and then repeating the first step, sometimes it rejects it, other times the following dialog shows)... click "Open" in the dialog that follows to confirm:

Screen Shot 2020-10-21 at 9.34.58 PM.png

and from there(load a patch or create one that uses the external as normal), the external can be moved anywhere and it remains available for that system anytime you want to use it again afterwards without having to go through the process again.

i believe there are 2 distinct issues being discussed. the gatekeeper issues are separate from the issue Micron had with the external not loading on earlier versions of the macOS.

apologies, completely my fault (i ran into this issue with my own external, but then couldn't reproduce the quarantine(didn't realize after an update to XCode, that it hadn't installed additional 'debug'related things yet(probably some things that allow me to build/test without quarantine under same admin account?), until I ran XCode a second time, got the dialog to install additional stuff, rebuilt, and no longer have any quarantine-issue), so i decided to try the steps out on micron's external to learn how to remove quarantine for sure, and was excited to find my solutions posted above).

still related to the thread, though: i'm looking at signing my external, but $99 seems steep just to sign one external to release for free. (i might do it, though), if there are any other options or solutions(upcoming or otherwise known), anyone with any information please feel free to link me... and i assume the starting information for how-to-sign can be found here, let me know if others have better sources:

If external is 32 bit only, your only chance is to use max 800 : the initial build of max 8.
