Ubuntu on Apple MacBookPro A1286 Mid 2012?

[kalpana]

Hi,
I am wanting to run Ubuntu Desktop on my MacBook Pro A1286 Mid 2012.
When I download the desktop version (Ubuntu 22.04 LTS.iso) and try installing it it just gives me errors!
I have tried Ubuntu Mate as well and it gives me the same errors.
Please can someone help me?
Thanks in advance,
Calvin
