I have a 21.5” iMac purchased 11/2017, Intel Core i5 chip. Plenty of free storage. I am still running Sierra 10.2.6 (I regret having to to say it) and want to finally upgrade. I understand that the major OS overhaul happened with Catalina and I am asking it might be safer to first upgrade to Mojave and as a second step upgrade to Big Sur or Ventura? What are the risks of upgrading this way, and likewise the risks of going directly to the most current OS? Note: I intend to buy a new iMac in a year, 2 years latest. Better to wait on upgrading until then?

Show more upgrade from Mojave I have an early 2015 MacBook Pro with 264gb storage (60gb available) and 8GHz Ram. I updated it to Mojave 10.14.6 some time ago. Last year my wife got a new mac that had Catalina installed but quickly upgraded to Big Sur. I looked at possible upgrades for my MBP, seemed, at that time, my system requirements were not up to the upgrade. But now I see that Catalina, Big Sur and Monterey are all compatible. I use photoshop and Lightroom, both now requiring Catalina or newer for current and future upgrades. My question is, which upgrade should I go for? Pro's and con's Thanks in advance and be gentle, I'm a software novice Cheers Roybosh Move from High Sierra to Mojave ?
I have a 2013 MacBrookPro, running High Sierra 10.13.6 with 16GB memory with a KINGSTON SUV500480G Media hard drive. The MacBook is solely used for home use/recreation, no work, no gaming or heavy graphics and I certainly don't use it to anywhere near what it is capable of (I find a paper clip technically challenging !) High Sierra is now somewhat dated as an OS and I was wondering if it might be a good idea/time to upgrade to Mojave ? I have never been one to jump onto the latest OS from Apple, always thinking that waiting allowed bugs to be ironed out and the OS tweaked so it is OK. So, is upgrading to Mojave a good idea ? Comments appreciated. Thanks Brian.
Hello, I would like to upgrade my MacOS from Sierra. I have a MacBook Pro (Retina, 13-inch, Late 2013) with about only 60 GB free space. I am unsure which upgrade would suit me as the Mac is pretty dated (still fully functional and fast though) and would not like to burden the hardware with a MacOS that is too new and too "loaded", thus resulting in a worse user experience for me. Which MacOS would you recommend to me, so that I have the same speed as now (or more of course) and would not take more space? I´ve been away from tech and upgrades in many years, so I need advice from more knowledgeable up-to-date users. Thank you in advance.

This is very helpful. A lot to digest. Thank you. Should have noted I have 8GB Memory and 427GB of 1T storage free (an iMac 18,1). Factoring in the 64-bit jump with OS15 (thanks for pointing that out) I'm considering upgrading to 10.14 and stopping there until I replace my iMac. And maybe offloading old apps before the new Mac.
