Tonight I put together some of the ideas in this thread (with some other things on the web) and got my Arduino working again on El Capitan. At the same time a kernel task would spin out of control hanging machine so it appeared to be some problem with the serial driver. My experience is if you do upgrade you may well find a few issues to solve so you will need to systematically go through all the apps you use and test them, including all your email accounts.Using El Capitan 10.11 I could not connect to Ardunio UNO - The Arduino IDE (v1.7.9) would compile my code then hang on communication with the board. Summary: Yes, you can upgrade to a later OS but may not easily be able to go back to El Capitan if you want or need to. This all being said, I give Apple a lot of credit for allowing a 10yr old computer to run very well on aging software, I mean in the high tech world, everything is pretty much obsolete in much less time. I will simply stay with El Capitan until I buy a new Mac. I upgraded to High Sierra and it destroyed my internal graphics card and due to this I was able to go back to El Capitan after replacing my graphics card. Safari under El Capitan is becoming incompatible with some websites and will exhibit strange behavior at times. Apple only supplies security patches for El Capitan and nothing else and if you contact Apple Support, they really frown upon helping people running El Capitan yet will do it as much as they can. The biggest issue with it now is that day by day its becoming incompatible with upgraded apps from third party suppliers (Microsoft, Adobe, etc) as they release newer apps made for more recent OS's. Might depend on how tech savvy you are and your level of risk acceptance.Įl Capitan, while not being very 'iOS'-like, is a very stable OS.

Ok, it can be done but you really have to search to find out how to do it as Apple is more of a one way upgrade company. Plus, you run the risk of not being able to go back to El Capitan if you want to. However, my experience upgrading to later levels of OS's on old hardware is not all that great. Of hand I think there are Sierra, High Sierra, Mojave, Catalina. Mac's running El Capitan are supposed to be able to run Catalina, which means you have a few higher level of OS's that should be able to run on your Mac Mini.
