Re: Upgrade OS from High Sierra on 2018 iMac
If the problem is browsers that are not supported, perhaps all you need to to is update the browser. ?I have macs at 10.13, 10.14, 12.6 and 14.6. ?They all work fine with the latest versions of the software they can run, and with very few exceptions, the more up to date Macs are not better at anything. ?

I have a new Mac Mini, 16/256 (currently 75 GB available) with the latest Sequoia update.? Attached to it is a hard drive enclosure that I¡¯ve been using for a couple of years with a 2015 iMac, 16/1T running Monterey.? With the iMac the hard drives would spin up and stay running while the iMac was in use.? With the Mac Mini the drives spin up when I wake the Mini but are regularly spinning down and then almost immediately spinning up again. I have turned to OFF ¡°Put hard disks to sleep when possible¡±. Any idea as to how to stop the drives from spinning up/down so frequently? ?I am hoping this may be due to the small internal storage, which I have ordered a 2TB replacement, and maybe this will solve the problem with the external drive.?

Thanks in advance to responses.?

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

Re: Upgrade OS from High Sierra on 2018 iMac
Thanks for replies so far. I'm keeping some to ponder.
I don't think I've ever purchased any software for this iMac. The most important apps I use: Browsers: Brave, Safari, Chrome (when nothing else works) Preview Notes LibreOffice Numbers Grab iTunes (nothing of note downloaded on my computer) For email I use my ISP's webmail. And that's where I back up some important files. Pretty basic! I still use old versions of Photoshop & Illustrator on my old iMac when I really need a feature. And I still occasionally use other apps (e.g., PageMaker) on my old iMac to update some docs.

And you may have to again purchase some of that when moving past that. That will minimize your expenses on new versions of software licenses and subscriptions.
Last year, I moved to Catalina, to try to keep the browsers working, but I am limited again as to which browsers are available and which are still accepted on certain sites.?
I suggest that you only jump one or two OS at a time to minimize the hassles. There are some converters buried in the upgrades, that convert your docs and data as you move up the line for both built-in and third-party software. I believe there is a ¡°catch¡± in moving from Mojave to Catalina for MS Office for the purchase version, rather than the subscription. Mail is another. The stuff in iTunes becomes several different apps, and there is a learning curve of both vocabulary and workflow changes that need to be learned. I would definitely research upgrading the 2 or 3 most important apps that you use, before advancing.?
Oh, btw, there is no 2018 iMac, so I assume you have one of the four 2017 versions.

Re: Upgrade OS from High Sierra on 2018 iMac
My copy of MacTracker (7.13.5) shows four versions of 2017 iMac, and the next entry is 2019, similar to what Bev said. The four versions had different maximum OSes.?
MacUpdater is a good idea, but how does it handle paid versions? I also like you comment about future proofing in a another reply you made, if the person has the finances to do so. Don¡¯t forget the cost of some replacement software, accessories (say if the printer stops working, and new cables and adapters, or case for things like phones or laptops,
