How can I altered to be able to upload the system to the latest version?
Google DosDude1 to find the patchers. Fair warning I don’t recommend running on your primary system and the needed resources RAM & Storage (besides the CPU) will be a limiter of having that useful a system. Lastly, Apple has moved to a new file system APFS from HFS+ with doesn’t run very well on older SATA based drives. You also will be limited on some OS enhancements as your system won’t have the needed hardware, so consider that as well.
