I have a Late 2015 27" iMac and just found out that because Apple won't let it upgrade to OSX 13 that I cannot run the current version of TurboTax. I am sure there are many more programs that will also be impacted. Now before you all get on me about this, realize that with my iMac I got the upgraded video card, have the 3TB Fusion Drive and added 32GB of RAM. I have no idea why this can't be allowed to download the newest OS. After thinking about it, I said, maybe I should just get a mini and use this iMac as a monitor, right? Wrong. Apple had a display port on the 2009-2014 iMacs and then removed it in 2015. My iMac runs perfectly and I just can't believe that with all the "reduce your carbon footprint" stuff that Apple won't even let me use this as a monitor.
Now I'm faced with just putting this in the closet to collect dust. This is such a WASTE.
I understand that Apple tests their new software with older Mac's and can see that the system may run slower or have some risks that we don't know about, but how about let us load it and give us a warning that we acknowledge that we are running it at our own risk? Or how about a version that has some of the features turned off? Or how about just using it as a monitor?
Come on Apple.
My 2017 27” iMac that cost more than three grand when I bought it in 2018 won’t run Sonoma for no good reason other than forced obsolescence. There an app for that!
OpenCore Legacy Patcher is your friend!!! Grab a thumb drive with 16 GB of disk space, download and install it on your Mac, run it, pick the OS you want to load, plug in that drive and it’ll download the version of Mac OS you want to run and it’ll create a USB based installer on that drive that lets you upgrade the OS. Just be sure to open the software annd then create a partition on the SSD of your Fusion Drive to create the partition that acts as a boot manager for the OS or you have to boot it from the USB drive every time.
You can run an even a newer version of MacOS than Apple allows you to. You might be able to install Sonoma but even if you can’t on your 2015 iMac you will be able to install Ventura (MacOS 13) and run TurboTax.
Check your make and model against the list on the website and you can see which version of MacOS you can run on it and what, if any, limitations it might have and you’ll be able to upgrade your iMac to a newer OS. Mine runs Sonoma just fine. Of course sooner rather than later they’ll stop releasing versions of MacOS that can run on Intel processors.
I believe the last Intel Macs were released in 2020 so there’s a chance the next version of MacOS won’t support Intel processors at all though I’d think to give users who bought new machines at least 5 full years of support for the latest OS that the next version of MacOS will still support Intel processors but that’ll likely be the end of road.
Either way, squeeze an extra few years out of it by going to Ventura or Sonoma. Just get a good backup of your machine in case there are issues post install but I don’t think you’ll have a problem. I haven’t had any so far. Touch ID wouldn’t work for me but I don’t have a keyboard with TouchID built into it so I didn’t care about that. Obviously Apple Intelligence doesn’t work either because it’s an Intel processor.
Also be sure to run the function that installs root patches after the new OS first boots the first time and again anytime you install an OS update to a new version. When Sonoma boots after I install a new Sonoma point release, and initially after I installed Sonoma, I had no wireless connectivity. Installing the those root patches are the key to getting the WiFi (in my case, I’m not sure what hardware you have that may not work right until you install the root patches) working again, install them, restart the computer and the hardware that doesn’t initially work will start working again.
