macOS Unable to install Quixel Mixer
Completed
Hi, I initially started installing and downloading all the content with the Quixel Mixer 1.5 Beta, during install I forgot to leave my MacBook Pro (late 2019 Mac OS Catalina Version 10.15.7) on charge so the battery died before the install was complete.
I tried finding any temp data and directories downloaded and made by the installer but I can't find them. I got to this screen and this happens 
I was able to get around this by running the launcher directly with sudo from terminal but again got stuck when trying to re apply /QuixelMixer (mixer path)
I would advice to have a Uninstall program in the installer that can remove any privileges and directories made by it to avoid this happening int the future.
Any idea how I can resolve my issue?
You guys are awesome!
Best regards

Hey Chazz1284
In order to solve this issue, kindly follow the steps mentioned below:
First of all, we need to check if there is any cache data present for Mixer. The temporary cache folder in ios is a special folder that maintains the cache. We need to make sure the cache is removed before installing Mixer again.
To access it:- Open Finder.
- Press Command+Shift+G to open the dialogue box.
- Input the following search: /var or /private/var/folders
- Now you should have temporary access, so you should be able to drag it into the Finder favourites if you want to access it again.
It would be something like:
var/folders/90/g7d3q1656151z0tvqd5fx7pc0000gn/T/Quixel/Quixel Mixer/PaintCache
-Delete the Quixel Mixer folder.This path varies from user to user. So it would not be same on different machines.
Now, moving to the next part...
There are a few paths that Mixer needs, in order to run properly in your system. These paths store the Megascans library as well as the Mixer files that you may need to launch a Mix.
So, what is a local library path?
Local Library path: It stores the Megascans Library in your system and should point to a Megascans library folder. If you are using Quixel Bridge already, then the local library path for Bridge and Mixer should be same.
Therefore, using just /Library as your library path would be pointing it to the main library folder of Mac. Which your system might not accept as it is a system folder. For example, you can create a new folder within the folder or in the users folder where you have other stuff stored and then point it there. You can name the folder as MSLibray or Megascans library or what ever suits you.
It can be created in a location like in the screenshot below as well.
What is a Mixer files path?
Mixer Files: It should point to the path where you'll store the Mixer Projects/Mix. It will store all your Mix and projects along with their essential files which will be required to launch a Mix. Afterwards, you'll be able to access your Mix through this folder in Mixer.
I'm going to attach a screenshot below that will explain the paths:
And when doing this, please make sure you are using the system with admin rights( with all the permissions required to install apps and access them) and its not a part of any server.Keeping in view all the points mentioned above, run the installer now and see how it goes. :)
In case you require further assistance, please let me know.
