The problem

If you're a Mac user and experiencing any of the following, this article is for you:


  • Seeing a fully blank screen
  • Shift is not launching
  • All email accounts have disappeared and being prompted to upgrade

Note: if Shift is not launching, it may be due to your antivirus software blocking 3rd-party applications. Try temporarily uninstalling your antivirus program, then re-launch Shift. More on this, here.


The solution

First and foremost, please check what version your Mac is using. You must be using 2.13 Version 10.11: "El Capitan" or higher. If you're using 2.12 Version 10.10: "Yosemite" or earlier, Shift will not work. You must update your Mac to a later version to continue using Shift if you're currently on Yosemite. If you're already running a version higher than Yosemite, continue reading!


If you've already confirmed you're using 2.13 version 10.11 or higher, a manual app data reset is what is usually needed and almost always helps set things right. Don't worry, your setup will be intact after a reset. You won't need to set up Shift again. The only thing you'll need to do is sign back into your emails, apps, and extensions afterward. Follow our easy steps or watch the video below! 👇



  1. Ensure Shift is fully closed and not running in your activity monitor (press Cmd Q to fully quit Shift if Shift is not in fullscreen mode)
  2. Pull up your system-wide search and look for Activity Monitor, then end any Shift processes
  3. Click on your desktop to move the focus away from any other apps, then choose "Go" from the top menu
  4. With the Go menu open, hold down the option key to reveal the hidden folder Library, then click on it to open
  5. Double click on the "Application Support" folder to open
  6. Find and delete the Shift folder from within Application Support (~/Library/Application Support/Shift)
  7. Open Shift and log in with your Primary Shift Account
