Markf028 Posted November 1, 2016 Share Posted November 1, 2016 Hey guys, I have successfully installed Yosemite on my Dell Inspiron 3521 using this guide - http://www.insanelymac.com/forum/topic/299911-dell-inspiron-3x21-5x21-clover-install-guide-dell/?hl=+dell%20+inspiron%20+3521 Massive thanks for that, too! However, I wish to now update, or fresh install Sierra using the same guide. I have tried to follow it to the best of my ability, however, I cannot boot into the installer. Is the method above no longer applicable for Sierra, or am I doing something wrong? I will answer any questions you may, or may not, have for me in a bid to solve my dilemma! I have also tried to update my Yosemite install directly, by downloading Sierra from the app store, updating clover and copying essential kexts to the other folder. This results in a circle with a diagonal line through it! I do hope some light can be shed, and I do apologise for being a bit vague - I'll add any information needed, should I be asked for it. Thank you for your time, any help will be appreciated! Link to comment Share on other sites More sharing options...
CooSee Posted November 1, 2016 Share Posted November 1, 2016 hello, i assume the CPU will not suffice for Sierra. CPU must have SSE 4.1 greetings Link to comment Share on other sites More sharing options...
