how to update from high sierra to mojave

I will, of course, have a backup from Time Machine before I start anything. Am I really looking at an overnight upgrade?Īt the moment those are my main questions. I think it took about 1.5 hours to upgrade from Sierra to High Sierra and a typical ‘point-update’ takes about an hour. I’ve read a bit on the Apple support site about upgrading to Mojave and to Catalina, and they suggest starting the upgrade in the evening so that it can run overnight if it needs to!! That seems like a very long time and although the internet connection and electrical power is pretty stable, it’s certainly within the realm of possibility that either or both could fail even if only very briefly. The current major user of this computer is highly reliant on two installed printers and a bunch (maybe 20 to 30?) of programs. I did that when the machine was only a month old and hardly any programs and no printers had been installed. I’m assuming that at least in principle all the current programs and printers will get carried over to the new Mojave installation? The only other major macOS upgrade I’ve ever done was on this computer going from Sierra to High Sierra.

But, the icon has been there for at least several months (I’m not the primary user of this computer, all I do is keep it updated), so I’m wondering if I’ll get the latest version of Mojave, or if you will, the latest up-to-date version of it? I’m assuming that clicking on this is an easy way to install Mojave. When I open the Launchpad I see an icon entitled ‘Install macOS Mojave’. There are some 32 bit programs on this machine that I don’t think Catalina or higher will run, and I’ve also not been terribly impressed with what I’ve heard about Catalina. Sometime in the next few weeks – before Big Sur comes out and High Sierra is no longer supported – I’ll be upgrading an iMAC from High Sierra to Mojave.
