Hi I recently bought the new Football Manager 2019 to play on my mac. I downloaded it all fine and when I went to launch it I couldn't. Said my operating system is too old. Now Steam won't even launch on my computer anymore. Is it possible to update the hardware on my 2009 iMac to avoid having to buy a brand new one? I currently have Mavricks and i believe even the next operating system Yosemite would be enough to run the game.

My computer is
Processor 3.06 GHz Intel Core 2 Duo
Memory 4 GB 1067 MHz DDR3
Graphics NVIDIA GeForce 9400 256 MB
Software OS X 10.9.5 (13F1134)

Any advice would be great!

I do see that Steam does not support any Mac system older than El Capitan. That changed on Jan 1, 2019.
That means that Yosemite (10.10.5) would also not be supported.

You can follow the steps to upgrade to El Capitan here - https://support.apple.com/en-us/HT206886
Hi, Thanks for that. Ive just looked at that and it should be able to install on my iMac as it says 2007 or newer and I have all the relevant space needed but it says my computer can't update to this version. Any ideas?

You should install the most recent OS available for your computer. A late 2009 iMac runs macOS 10.13.6 maximum, which means you should download the High Sierra.

You may also consider upgrading the amount of RAM. This computer takes 16 GB maximum and with the prices of RAM nowadays it will cost next to nothing. Even 8 GB will do miracles in regards to usability and comfort, especially as you do not have an SSD disk.

My computer isnt letting me update beyond 10.9.5. If I try newer it says that my computer can’t update. Any ideas why that would be?

Did you try starting it up from a bootable USB installer instead of running the installer straight from the Mac OS?
What is your date, including year, and time set to?

My computer won't let me download it so i can't try and boot it from USB. Is there somewhere i can download the install?

Sorry I'm not sure what you mean by date, year and time?
thanks for your time
Richard

If your iMac is an early 2008/9 24" model it can handle El Capitan OS X.11.6.

Do you have an Apple ID in order to download from the App Store? Here is a link explaining how to do this, and under 'Learn More' toward the bottom of the page is a link to download El Capitan.

Then use DiskmakerX to burn the Installer to an 8GB thumb drive, boot from this and run the Installer. Make sure you download the El Capitan compatible version, 5.0.3.

Pics tell it's a late 2009 so High Sierra.

@sl1ppers - skip Sierra and get High Sierra right away from here: https://itunes.apple.com/us/app/macos-high-sierra/id1246284741?mt=12 No matter which Sierra you got, use https://macdaddy.io/install-disk-creator/ or DiskmakerX mentioned kindly by @nambuccaheadsau to create your installer.

If it doesn't work, crawl your way through Sierra to HS, most probably you will not need to create another installer, just install HS right away.

And yes, I was asking if your clock and date in your iMac are set properly, because if not, then funny thing happen with secure communication certificates (like they are not recognized and you can not download some stuff, including MacOS).
