This article lists which systems can support which versions of Scratch.
- macOS (OS X) 10.13 or later (although the Mac App store shows Scratch Desktop as being for versions 10.11 and later)
- Windows 10 or later[note 1]
- Android 6.0 or later on tablets
Scratch Desktop is not supported for Linux, however, there is a version which can run on Raspberry Pi OS and it is normally installed by default but can be installed via the recommended software menu. See the official page on the raspberry pi website.
- Chrome 63+ or Mobile Chrome 63+
- Edge 15+
- Firefox 57+
- Safari 11+ or Mobile Safari 11+
- Mac OS X — a Mac with an Intel processor
- Windows XP or later
- (GNU/)Linux — Fedora 13, Ubuntu 10.10, or openSUSE 11.3 or later
- Requires Adobe AIR
The Scratch 2.0 Offline Editor can be downloaded at scratch:download/scratch2.[note 2] For macOS 10.10 and later or Windows 7 and later, the latest version of Adobe AIR may be downloaded here. For Linux and older operating systems, the AIR 2.6 runtime may be downloaded here. In the latter case, you must download the "Mac OS 10.5 & Older" version of Scratch.
There is also an online version of Scratch 2.0, which is compatible with all devices that support Flash Player 10.2 or later. A test to see whether a device has Flash properly installed is available here. If a blank page is displayed Flash is not installed properly.
Until the release of Scratch 3.0, the online 2.0 editor could be found at projects:editor. This is no longer the case, but ScratchX, which is very similar to Scratch 2.0, or s2online, an unofficial version of Scratch 2.0, may be used instead.
- Mac OS X – Compatible with Mac OS X 10.4 to macOS 10.14.6
- Windows – Compatible with Windows 2000 or later.
- Debian/Ubuntu/Linux Mint – Compatible with Ubuntu 12.04 (Precise Pangolin) or later.
- Despite not being officially supported, Scratch Desktop does work on Windows 7.
- Alternatively, a specific version of Scratch 2.0 may be downloaded from https://scratch.mit.edu/scratchr2/static/sa/Scratch-VERSION.exe (the version shouldn't have a "v" at the beginning, so for example version 451 has a URL ending with Scratch-451.exe). Replace .exe with .dmg for macOS or .air for Linux and old macOS versions (10.5 or older)
