McPants Posted September 16, 2015 Share Posted September 16, 2015 Hey guys, I am having a problem when I boot the apple logo turns into a "no entry symbol" or "no smoking looking symbol." When this happens, I typically just power down and reboot and it usually works after 2-4 tries. It has been doing this for a good while and it is pretty annoying. I just want to work this out once and for all. My system is: Gigabyte z87 ud5 th i7 4790k evga 980 GTX sc 32gb ram 512 SSD (trim enabled) If you guys need any other information let me know. I greatly appreciate all of your help in advance! -McPants Link to comment Share on other sites More sharing options...
golfleep Posted September 16, 2015 Share Posted September 16, 2015 Are you using Clover as a boot loader? I have a similar setup, Gigabyte Z97X-UD7 TH with a 4790K, Crucial SSD, and have the same problems with intermittently getting the stop sign. I have a workaround, but have not a found a solution, nor do I know why my workaround works. Basically, if I wait about 3-4 seconds after reaching the Clover screen before selecting a boot drive, I can boot without getting the stop sign. If I select a drive immediately after reaching the Clover screen, I will get the stop sign 50-75% of the time, regardless of whether it's a restart or a cold boot. I initially thought it was because I never configured which hard drive to use in the clover config.plist, but setting a correct value did not change getting the stop sign. Nether did changing the timeout value, etc. I believe it's somewhat hardware related (whether it's the mobo, SSD, RAM), because I have an Asus Z97 hack as well, with the same setup, and never have gotten the stop sign. Be interested to know if just pausing before selecting the boot drive works for you, or if you make any progress. Link to comment Share on other sites More sharing options...

Needy Posted May 19, 2016 Share Posted May 19, 2016 Hello there,What does verbose boot say? Could you post some pictures?Furthermore, I'd recommend enabling the debug mode in every section of the config so it'll be easier to narrow down the problem.Best regards. 1 Link to comment Share on other sites More sharing options...
annabel82 Posted May 19, 2016 Share Posted May 19, 2016 Hi Needy, verbose shows nothing at all, just a completely black screen. i am a little lost as to what you mean by 'enabling the debug mode in every section of the config" i assume you mean config.plist?

Needy Posted May 19, 2016 Share Posted May 19, 2016 Hi Needy, verbose shows nothing at all, just a completely black screen. i am a little lost as to what you mean by 'enabling the debug mode in every section of the config" i assume you mean config.plist? Yes, clover's config.plist. If you're using clover configurator there is a debug option in acpi, boot and kext to patch. Otherwise, use clover's wiki to add the needed entries in the config. In addition, add the, -v, boot argument in the config.plist file. Best of luck. Link to comment Share on other sites More sharing options...
annabel82 Posted May 19, 2016 Share Posted May 19, 2016 Will this help if -v is outputting nothing at all? Also: thanks for your help x Link to comment Share on other sites More sharing options...
