hi - i have a late 2014 imac. For some reason i am still stuck on the Yosemite OS and there are no updates available in system preferences and / or app store. Does anybody know why this would be and how to fix? I appreciate its an old model and might not be compatible with Monterrey but surely i can get more recent versions than Yosemite? thanks
iMac 27″, OS X 10.10
The Age of this computer will Govern what newer version of macOS it will Qualify to install. Use About this Mac from the Apple Icon on Desktop - the required Information will be there.
With the above information in-hand - follow this How to get old versions of macOS and verify what version this computer Qualifies to install. For Best results use Safari to commence the download as Others may not work.
One may consider upGrading to High Sierra first. This may better position the computer for the Drive Conversion to the newer APFS format as well as any EFI BOOT ROM required to use the newer file format.
Make Time Machine Backup is very useful and can be used to Revert to Previous Working macOS
Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina, Big Sur & Monterey supports only 64 bit and there is no workaround.
Suggest using Go64 to find 32 bit application before attempting the upGrade. Some or many of the Application already installed may required update or upGrades to 64 Bit Versions.
Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation

Thank you very much. Interestingly I tried high Sierra first but the download from the App Store was corrupted so I went straight to Mojave and that worked fine. All works fine now. thanks again
