Sometimes I am hitting the limits (for example when running an iOS simulator and having too many other programs running at the same time), however I am always able to just close the ones I am not using right now and get everything to run fluently again.

iOS 7 or later ROM image from Mac Plus, Mac II and/or Mac 128K Disk images with Mac software. In general I am very happy with it, everything works fine (not super fast, but not too slow either). This is my port of the Mini vMac emulator to iOS 9. Just wanted to give future visitors an update: I spent a few hours to test macinacloud, however since it felt pretty slow and a bit overcomplicated, in the end I decided to get a used Mac Mini from late 2014 with 8 GB RAM. I'm happy about any comments about RAM, Processor, manufacturing year or anything else. This is REAL emulation on iPad Pro thanks to QEMU and UTM. I know this has been asked before, but it's been a few years since then, that's why I ask again. Quinn runs Windows, macOS, Android, and more on his iPad Pro. The app I want to develop is mostly running in the background, so there will be no heavy graphics or computations. I do not have a high budget, which is why I would prefer to buy a (used) Mac with the minimum required specifications that is able to run the latest version of Xcode and iPhone simulator. I need to buy a Mac to run Xcode for iOS app development. I'm planing to develop an app with React Native for Android and iOS.
