I have a late 2011 Macbook pro, 2.4 GHz Intel Core i5, with 4 GB of 1333 MHz DDR3 RAM. It is currently running version 10.7.5. According to EveryMac "... this model is capable of running macOS High Sierra (10.13), and it supports HEVC (High-Efficiency Video Coding), but it does not support hardware accelerated HEVC."
- When I open the apple menu and click 'Software Update' it says 'Checking for new software' and then 'Your system is up to date. Software Update doesn’t have any new software for your computer at this time.'
- I tried a manual update by executing a command line in terminal:
sudo sh -c “softwareupdate -ia && reboot. This should update it, but it only reboots the computer.
- I tried downloading the update from apple: https://support.apple.com/kb/DL1760?viewlocale=en_US&locale=en_US The download button is missing from the page in both Safari and Firefox, it's only an empty square with the text 'download icon' in it.
How can I upgrade to High Sierra?
