I have a late 2015 iMac. It has run slow for a number of years, even with the OS on an attached SSD drive. I decided to restore the iMac to its original OS, but this has caused some issues.
I had to do the shift-cmd-option-R to get the OS to restore, but now I cannot move the OS further than the original which was El Capitan. I have tried to do a software update (of which it says that there are none available) and also visited the Apple download centre to try and manually download the next OS (Sierrra) but it is not available from the site. Any help with this would be much appreciated.
Thanks
