I'm following this tutorial for debugging a sideloaded Excel add-in on Mac:
https://docs.microsoft.com/en-us/office/dev/add-ins/testing/debug-office-add-ins-on-ipad-and-mac
And using Mac OS 10.14.4 and Office 365 Excel version 16.24 (19041201). After adding:
defaults write com.microsoft.Excel OfficeWebAddinDeveloperExtras -bool true in the terminal, and rebooting: "Inspect Element" does not appear in right click menu inside my Office add-in, in Excel.
Is it because I have a newer OS than High Sierra? Any Ideas?
Inspect Element should appear in right click menu so I can access the inspector on mac and be able to debug. This is for an add-in/manifest that works as expected in Windows 10.
Inspect Element does not appear in the right click menu.
Would like to be able to debug on mac (mainly view the console)
The same happens to me

@keyur32, Can you please take a look?
Please see the documentation:https://docs.microsoft.com/en-us/office/dev/add-ins/testing/debug-office-add-ins-on-ipad-and-mac#debugging-with-safari-web-inspector-on-a-mac
@akrantz This should the correct configuration right?
> defaults read com.microsoft.Excel OfficeWebAddinDeveloperExtras

With that setting I can't open Inspect Element. I think this issue started after a macos update (i'm on 10.14.5)
Yup, we are investigating this. We will respond once investigation completes. Have added a bug label to this issue. Thanks!
Hey folks, sorry! we haven't been able to repro this across multiple machines on 10.14.4 and 10.14.5 -- it all works, when we set it. We may need to jump on a call. + @JuaneloJuanelo / @akrantz to help coordinate that..
Hi @keyur32, any update here? I'm on macOS 10.12.6, word 16.27, and I have the same problem. I'm happy to help you with debugging if you need anything.
edit:
My mistake didn't saw High Sierra requirement, after updating macOS to 10.13.1 it works. 馃憤
_At the same time, I also cleaned cache._
I'm also having this problem with mac OS 10.14.5 and outlook 16.27
Hey folks, can you verify your writes command was set:
https://docs.microsoft.com/en-us/office/dev/add-ins/testing/debug-office-add-ins-on-ipad-and-mac?
thanks!
Still doesn't work

MacOS 10.14.4 (18E226)

Update: We think this is specific to the Mac App Store Build of Office, which currently doesn't support these flags. To workaround this, you will need to get a non App Store build. You can get one by signing up for the developer program and getting a tenant: https://aka.ms/o365devprogram.
Closing this issue, as it seems like @keyur32's most recent comment explains root cause and identifies a work-around. If you need further assistance with this issue, please comment here and we'll re-open it. Thanks!
Hi, I have the same issue this time on macOS: 10.15 and word: 16.29
Did you install Office from the App Store? You will need to install it from https://www.office.com to get access to debug capabilities.
@keyur32 can confirm using non app-store version shows the inspect element. Would be nice to have docs updated regarding this :)
Re-opening and tagging @keyur32 and @RuoyingLiang
Yes, (sorry didn't see this one). Non app store version should have the ability to debug.
