Downloaded Visual Studio installer from https://visualstudio.microsoft.com/vs/mac/ first and started the download and install process.

At the end of the installation process, it came up with the following error. all things were run with admin permissions.

Installation of 'Visual Studio' failed with exception.

For now, I have been struggling a complete day trying to set up this with different combinations.

Dev environment

OS version : Mojave (10.14.5)
xCode version : 10.2.1
Visual Studio for mac v8.5.2 (build 13)
.NET Core SDK : 3.1.201
.NET Core Runtime : 2.1.16

Things did so far

removed all the partially installed files and did a clean install. https://social.msdn.microsoft.com/Forums/en-US/6a94b169-82c3-4ace-8de1-0c090e67a198/cant-install-mac-visual-studio-2019-community?forum=vssetup
Installing by removed different component combinations(Android, iOS SDK, .netCore)

referred links

none of above is worked for me, any suggestions would be appreciated.

I came across the similar problem. Because macOS needs a permission to copy files while installing but for some reasons a popup doesn't show, it's failed to copy. Therefore, click retry until a pop up appears to type the password of logged user.

Solution 2:^[2]

Found a workaround for this.

Visual Studio for Mac installer will download all the components needed to install Visual Studio once you pass the following screen, Which will be stored in your /Users/user-name/Library/VisualStudioInstaller/downloads

You can directly navigate here using shortcut cmd+shift+g

Then run the installation and waited for failing. find the Log report at /Users/user-name/Library/Logs/VisualStudioInstaller and that contains all the steps passed and failed. Depends on the failing point you can choose what to do.

Read the reason for the failure in log report clearly. In my case issue is moving files with NSFileManager and the log file shows that the rest of the components are installed correctly.

So manually installed the visualstudioformac-8.5.2.13.dmg from the downloaded directory explained in step 2. that worked for me.

Solution 3:^[3]

Same issue installing Visual Studio 2022 for Mac (Preview)

What worked in my case was mounting the downloaded .dmg as sudo and running the installer as usual via Finder.

sudo hdiutil attach lalala.dmg

Solution 4:^[4]

this is quite weird, I encountered the same issue and what I did was keep clicking the "retry" button every time till it popped up the window that required you to enter password for permission. And then it won't fail anymore...

Solution 5:^[5]

I actually found out that the app was copying anyways into Applications, so just waited for it to finish the copy and then the password dialog popped up and clicked retry and worked. The problem with keep clicking retry was that it created a copy of the app every time
