Sometimes, newer app updates do not work well on older devices, which can lead to installation or performance issues. It is also possible that new versions of Scratch may be faulty due to incompatibilities with some Mac architectures. While the development team works on a solution, you may consider using an older version of Scratch. For this purpose, Uptodown offers an extensive Scratch version history, where you can find the previous files available. Download previous versions of Scratch for Mac from Uptodown, virus-free and free of charge.
