running High Sierra and I cant down load any apps

I just picked up a computer running High Sierra and I can't download any apps.


(null) can’t be installed on “10.13” because macOS version 10.14 or later is required.


Is there any hope for this computer?

iMac 27″, macOS 10.13

Hello, gbb79.


Unfortunately that iMac (27", Mid 2010) has reached the limits of OS upgradability. macOS 10.13.6 is the end of the road. So, no, there is no hope for it.


If you must run any software that requires macOS 10.14 Mojave or newer you will have to buy a newer Mac.


From one user to another (of course) I find I can generally get about 10 years of good use from the Macs my fam and I have purchased before we ultimately give them up. And we don't give them up because they stop working, they simply can't keep up with the software.


Good luck. 🍀

User wrote " I just picked up a computer running High Sierra and I can't download any apps. " explain " Just picked up" as in purchased second hand, refurbished, private sale. Was this done before you took ownership What to do before you sell, give away, or trade in your Mac or will you have to do this the remove the previous Owners' Account from the computer ??



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. Make sure to use Only Safari to commence the download as Others may not work


Make a Time Machine Backup Before attempting. Notation - Mojave is the Last version to support 32 bit applications / extensions and Drivers. Catalina and Big Sur Only support 64 bit and there is no workaround.


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
