Quick-fire questions
Can macOS check iOS backups for malware?
> No it can’t. As far as we know, no Apple or third-party malware scanning software looks through your iOS backups. As they’re required to be encrypted if they’re to contain sensitive data such as health information, that puts them even further from the reach of any malware scanning.
Why should a new app warn it’s short of memory?
> Unlike macOS, iOS and iPadOS can’t use ‘swap’ memory to extend the physical memory in the device. When an iPhone or iPad starts running short of memory, all it can do is quit other apps running in the background to free up as much as it can, and that’s when you’ll see this warning.
