my 2021 desk mac has an M1 chip running OS14.5 will it update to 17.1 or later?

You are confusing IOS and IOS for iPad with Mac OS! Both IOS versions are on 17.x. Mac OS is currently on 14.x which your iMac can certainly run. You’re Mac will NOT run IOS and vice versa.

Hi,

As far as I know, your iMac upgradable to macOS 15 Sequoia which is coming soon.
