Note: The arm64 build on an Apple Silicon Mac runs natively. The x64 build on an Apple Silicon Mac runs under translation, and emulator performance drops.
System requirements
These cover the desktop app plus the Apple and Google tooling it drives. The tooling accounts for the disk and memory figures; the app itself is small.
Operating system
macOS 12 or later
Required by the Xcode versions Drizz supports
Processor
Apple Silicon or 64-bit Intel with virtualization support
Android emulators need virtualization
Memory
8 GB minimum, 16 GB recommended
Emulators, simulators and builds are memory-hungry
Storage
20–30 GB free for Android · 40–50 GB free for iOS
SDK packages, system images, Xcode and simulator runtimes
Network
Stable connection
SDK downloads, sign-in, device provisioning
Windows support
Every shipped desktop build to date has been macOS, in the two variants above. Windows is not supported.
The desktop app is not required to run tests on cloud. Drizz Cloud runs test plans in a browser, on any operating system.
Set up a device
A device is required before a test can run. The guided setup wizard installs and configures the Android and Apple tooling, and is the supported path. Open the Connect Device screen with nothing connected to start it.
Common mistakes
Download the Intel build on an Apple Silicon Mac
It runs under translation, slowly, and emulator performance is poor. Reinstall the arm64 build
Run Drizz from the mounted disk image
Updates fail, because the app can't replace itself on a read-only volume. Drag it to /Applications first
Sign in with a personal Gmail or Outlook address
Rejected at sign-in. Use your work email
Install with 10 GB free
The Android system image download fails partway through step 7 of the wizard. Free up space first
Expect the app to work with no Android or Apple tooling installed
There's nothing to connect to. Run the setup wizard
