Re: Upgrade OS from High Sierra on 2018 iMac
|
I was trained to do a clean install and always did it till this computer. But now I'm really afraid of trying it. What are the dangers if I don't? I do want to do a complete backup. I'm afraid of that too, but afraid not to. I'll buy a hard drive, probably locally at a Canadian retailer. They're a whole lot cheaper than they used to be! I have just about 100 GB on a 1.03 TB internal drive. And I can clean part of that off. New everything will take up more space. So I was thinking of a drive around 250 GB. Patsy

But, then that¡¯s probably just me. cjc On 22 Mar 2025, at 8:44?am, Jim Saklad via groups.io <jimdoc@...> wrote:

Now that I'm retired I use my iMac only for the basics. My iMac works just fine except that many websites now tell me they don't support my browsers. I knew this was coming!
I want to upgrade my OS from High Sierra to the latest. Mactracker says that a 2018-model-year iMac can run up to the "Latest release of macOS 13 Ventura¡±, but no further. Then, of course, I'll need to upgrade my apps. And then learn how to work with the new stuff. Can I do it all myself? Can you tell me exactly what to do? Or refer me to a resource? If this has all been covered here before, tell me where/how to look.
For updating apps, I personally use, and recommend, MacUpdater: <> Of course, by now it could be that some of your apps cannot BE updated¡
