How well does MacOS High Sierra run on an unsupported Mac?


This MacBook Pro from mid-2009 officially supports up to 10.11 El Capitan, but thanks to dosdude1, I’ve had 10.12 Sierra running on it for over a year, and it worked well. Now I’ve upgraded to 10.13 High Sierra, and yes, it’s still good. It works this well because there is a machine worse than this one (MacBook late 2009) which is supported!

However, if you also have an unsupported Mac and you have no real reason to upgrade, you might want to stick with El Capitan, most modern software still runs on it.
If your Mac is supported, definitely upgrade the OS, unless you have some software that isn’t compatible.

macOS High Sierra Patcher:
Future updates, like 10.13.2 and so on, should appear normally in the App Store app when they’re released.

To enable TRIM, which improves SSD performance in the long run, open Terminal and type: sudo trimforce enable

Video about upgrades and restoration of this computer:

Something I forgot to say in the video: when running Mac OS Sierra or older, this computer could provide power over USB in sleep mode, but now, with High Sierra, it no longer works (which means if you want to charge something over USB, the computer must be turned on all the time, it can’t be in sleep mode).
However, you can fix it by opening the “Patch Updater” application (you can find it in the Utilities folder inside your Applications folder) and installing the patches it finds.

  5. Have you ever replaced thermal paste on this Mac? I've recently got an MBP mid 2009 and wanted to upgrade with SSD and Ram, but first I wanted to clean inside to make it last longer, but I'm afraid that opening and cleaning the board will make some mess. What would you do? Worth the effort?

  12. TheComputerGuy96 Hi thanks for your informative video. I wonder if you still have the same opinions about downgrading high Sierra to El Capitan after 3 years passed? Now El Capitan is not supported by apple and high Sierra’s apple support will be ending up by December 2020.

  13. Should I buy a copy disk or will it not work?

  24. Just installed Mojave on my Mac Book Pro 5.1 (late 2008). Everything works fine so far…
    If you want to keep El Capitan you could partition your SSD and install a different OSX in each partition. Then you can choose the partition you want to boot from.
